By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + Appendix: How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) 19yy + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The +statistics are stored spread across the subdirectories of the +cache\&.

Normally the -c option should not be necessary as ccache +keeps the cache below the specified limits at runtime and keeps +statistics up to date on each compile\&. This option is mostly useful +if you manually modify the cache contents or believe that the cache +size statistics may be inaccurate\&. +.IP +.IP "\fB-C\fP" +Clear the entire cache, removing all cached files\&. +.IP +.IP "\fB-F maxfiles\fP" +This sets the maximum number of files allowed in +the cache\&. The value is stored inside the cache directory and applies +to all future compiles\&. Due to the way the value is stored the actual +value used is always rounded down to the nearest multiple of 16\&. +.IP +.IP "\fB-M maxsize\fP" +This sets the maximum cache size\&. You can specify +a value in gigabytes, megabytes or kilobytes by appending a G, M or K +to the value\&. The default is gigabytes\&. The actual value stored is +rounded down to the nearest multiple of 16 kilobytes\&. +.IP +.PP +.SH "INSTALLATION" +.PP +There are two ways to use ccache\&. You can either prefix your compile +commands with "ccache" or you can create a symbolic link between +ccache and the names of your compilers\&. The first method is most +convenient if you just want to try out ccache or wish to use it for +some specific projects\&. The second method is most useful for when you +wish to use ccache for all your compiles\&. +.PP +To install for usage by the first method just copy ccache to somewhere +in your path\&. +.PP +To install for the second method do something like this: + +.nf + + + cp ccache /usr/local/bin/ + ln -s /usr/local/bin/ccache /usr/local/bin/gcc + ln -s /usr/local/bin/ccache /usr/local/bin/g++ + ln -s /usr/local/bin/ccache /usr/local/bin/cc + +.fi + + +This will work as long as /usr/local/bin comes before the path to gcc +(which is usually in /usr/bin)\&. After installing you may wish to run +"which gcc" to make sure that the correct link is being used\&. +.PP +Note! Do not use a hard link, use a symbolic link\&. A hardlink will +cause "interesting" problems\&. +.PP +.SH "EXTRA OPTIONS" +.PP +When run as a compiler front end ccache usually just takes the same +command line options as the compiler you are using\&. The only exception +to this is the option \&'--ccache-skip\&'\&. That option can be used to tell +ccache that the next option is definitely not a input filename, and +should be passed along to the compiler as-is\&. +.PP +The reason this can be important is that ccache does need to parse the +command line and determine what is an input filename and what is a +compiler option, as it needs the input filename to determine the name +of the resulting object file (among other things)\&. The heuristic +ccache uses in this parse is that any string on the command line that +exists as a file is treated as an input file name (usually a C +file)\&. By using --ccache-skip you can force an option to not be +treated as an input file name and instead be passed along to the +compiler as a command line option\&. +.PP +.SH "ENVIRONMENT VARIABLES" +.PP +ccache uses a number of environment variables to control operation\&. In +most cases you won\&'t need any of these as the defaults will be fine\&. +.PP +.IP +.IP "\fBCCACHE_DIR\fP" +the CCACHE_DIR environment variable specifies +where ccache will keep its cached compiler output\&. The default is +"$HOME/\&.ccache"\&. +.IP +.IP "\fBCCACHE_TEMPDIR\fP" +the CCACHE_TEMPDIR environment variable specifies +where ccache will put temporary files\&. The default is the same as +CCACHE_DIR\&. Note that the CCACHE_TEMPDIR path must be on the same +filesystem as the CCACHE_DIR path, so that renames of files between +the two directories can work\&. +.IP +.IP "\fBCCACHE_LOGFILE\fP" +If you set the CCACHE_LOGFILE environment +variable then ccache will write some log information on cache hits +and misses in that file\&. This is useful for tracking down problems\&. +.IP +.IP "\fBCCACHE_PATH\fP" +You can optionally set CCACHE_PATH to a colon +separated path where ccache will look for the real compilers\&. If you +don\&'t do this then ccache will look for the first executable matching +the compiler name in the normal PATH that isn\&'t a symbolic link to +ccache itself\&. +.IP +.IP "\fBCCACHE_CC\fP" +You can optionally set CCACHE_CC to force the name +of the compiler to use\&. If you don\&'t do this then ccache works it out +from the command line\&. +.IP +.IP "\fBCCACHE_PREFIX\fP" +This option adds a prefix to the command line +that ccache runs when invoking the compiler\&. Also see the section +below on using ccache with distcc\&. +.IP +.IP "\fBCCACHE_DISABLE\fP" +If you set the environment variable +CCACHE_DISABLE then ccache will just call the real compiler, +bypassing the cache completely\&. +.IP +.IP "\fBCCACHE_READONLY\fP" +the CCACHE_READONLY environment variable +tells ccache to attempt to use existing cached object files, but not +to try to add anything new to the cache\&. If you are using this because +your CCACHE_DIR is read-only, then you may find that you also need to +set CCACHE_TEMPDIR as otherwise ccache will fail to create the +temporary files\&. +.IP +.IP "\fBCCACHE_CPP2\fP" +If you set the environment variable CCACHE_CPP2 +then ccache will not use the optimisation of avoiding the 2nd call to +the pre-processor by compiling the pre-processed output that was used +for finding the hash in the case of a cache miss\&. This is primarily a +debugging option, although it is possible that some unusual compilers +will have problems with the intermediate filename extensions used in +this optimisation, in which case this option could allow ccache to be +used\&. +.IP +.IP "\fBCCACHE_NOSTATS\fP" +If you set the environment variable +CCACHE_NOSTATS then ccache will not update the statistics files on +each compile\&. +.IP +.IP "\fBCCACHE_NLEVELS\fP" +The environment variable CCACHE_NLEVELS allows +you to choose the number of levels of hash in the cache directory\&. The +default is 2\&. The minimum is 1 and the maximum is 8\&. +.IP +.IP "\fBCCACHE_HARDLINK\fP" +If you set the environment variable +CCACHE_HARDLINK then ccache will attempt to use hard links from the +cache directory when creating the compiler output rather than using a +file copy\&. Using hard links is faster, but can confuse programs like +\&'make\&' that rely on modification times\&. +.IP +.IP "\fBCCACHE_RECACHE\fP" +This forces ccache to not use any cached +results, even if it finds them\&. New results are still cached, but +existing cache entries are ignored\&. +.IP +.IP "\fBCCACHE_UMASK\fP" +This sets the umask for ccache and all child +processes (such as the compiler)\&. This is mostly useful when you wish +to share your cache with other users\&. Note that this also affects the +file permissions set on the object files created from your +compilations\&. +.IP +.IP "\fBCCACHE_HASHDIR\fP" +This tells ccache to hash the current working +directory when calculating the hash that is used to distinguish two +compiles\&. This prevents a problem with the storage of the current +working directory in the debug info of a object file, which can lead +ccache to give a cached object file that has the working directory in +the debug info set incorrectly\&. This option is off by default as the +incorrect setting of this debug info rarely causes problems\&. If you +strike problems with gdb not using the correct directory then enable +this option\&. +.IP +.IP "\fBCCACHE_UNIFY\fP" +If you set the environment variable CCACHE_UNIFY +then ccache will use the C/C++ unifier when hashing the pre-processor +output if -g is not used in the compile\&. The unifier is slower than a +normal hash, so setting this environment variable loses a little bit +of speed, but it means that ccache can take advantage of not +recompiling when the changes to the source code consist of +reformatting only\&. Note that using CCACHE_UNIFY changes the hash, so +cached compiles with CCACHE_UNIFY set cannot be used when +CCACHE_UNIFY is not set and vice versa\&. The reason the unifier is off +by default is that it can give incorrect line number information in +compiler warning messages\&. +.IP +.IP "\fBCCACHE_EXTENSION\fP" +Normally ccache tries to automatically +determine the extension to use for intermediate C pre-processor files +based on the type of file being compiled\&. Unfortunately this sometimes +doesn\&'t work, for example when using the aCC compiler on HP-UX\&. On +systems like this you can use the CCACHE_EXTENSION option to override +the default\&. On HP-UX set this environment variable to "i" if you use +the aCC compiler\&. +.IP +.PP +.SH "CACHE SIZE MANAGEMENT" +.PP +By default ccache has a one gigabyte limit on the cache size and no +maximum number of files\&. You can set a different limit using the +"ccache -M" and "ccache -F" options, which set the size and number of +files limits\&. +.PP +When these limits are reached ccache will reduce the cache to 20% +below the numbers you specified in order to avoid doing the cache +clean operation too often\&. +.PP +.SH "HOW IT WORKS" +.PP +The basic idea is to detect when you are compiling exactly the same +code a 2nd time and use the previously compiled output\&. You detect +that it is the same code by forming a hash of: +.PP +.IP o +the pre-processor output from running the compiler with -E +.IP o +the command line options +.IP o +the real compilers size and modification time +.IP o +any stderr output generated by the compiler +.PP +These are hashed using md4 (a strong hash) and a cache file is formed +based on that hash result\&. When the same compilation is done a second +time ccache is able to supply the correct compiler output (including +all warnings etc) from the cache\&. +.PP +ccache has been carefully written to always produce exactly the same +compiler output that you would get without the cache\&. If you ever +discover a case where ccache changes the output of your compiler then +please let me know\&. +.PP +.SH "USING CCACHE WITH DISTCC" +.PP +distcc is a very useful program for distributing compilation across a +range of compiler servers\&. It is often useful to combine distcc with +ccache, so that compiles that are done are sped up by distcc, but that +ccache avoids the compile completely where possible\&. +.PP +To use distcc with ccache I recommend using the CCACHE_PREFIX +option\&. You just need to set the environment variable CCACHE_PREFIX to +\&'distcc\&' and ccache will prefix the command line used with the +compiler with the command \&'distcc\&'\&. +.PP +.SH "SHARING A CACHE" +.PP +A group of developers can increase the cache hit rate by sharing a +cache directory\&. The hard links however cause unwanted side effects, +as all links to a cached file share the file\&'s modification timestamp\&. +This results in false dependencies to be triggered by timestamp-based +build systems whenever another user links to an existing +file\&. Typically, users will see that their libraries and binaries are +relinked without reason\&. To share a cache without side effects, the +following conditions need to be met: +.PP +.IP o +Use the same \fBCCACHE_DIR\fP environment variable setting +.IP o +Set the \fBCCACHE_NOLINK\fP environment variable +.IP o +Make sure everyone sets the CCACHE_UMASK environment variable +to 002, this ensures that cached files are accessible to everyone in +the group\&. +.IP o +Make sure that all users have write permission in the entire +cache directory (and that you trust all users of the shared cache)\&. +.IP o +Make sure that the setgid bit is set on all directories in the +cache\&. This tells the filesystem to inherit group ownership for new +directories\&. The command "chmod g+s `find $CCACHE_DIR -type d`" might +be useful for this\&. +.PP +.SH "HISTORY" +.PP +ccache was inspired by the compilercache shell script script written +by Erik Thiele and I would like to thank him for an excellent piece of +work\&. See +http://www\&.erikyyy\&.de/compilercache/ +for the Erik\&'s scripts\&. +.PP +I wrote ccache because I wanted to get a bit more speed out of a +compiler cache and I wanted to remove some of the limitations of the +shell-script version\&. +.PP +.SH "DIFFERENCES FROM COMPILERCACHE" +.PP +The biggest differences between Erik\&'s compilercache script and ccache +are: +.IP o +ccache is written in C, which makes it a bit faster (calling out to +external programs is mostly what slowed down the scripts)\&. +.IP o +ccache can automatically find the real compiler +.IP o +ccache keeps statistics on hits/misses +.IP o +ccache can do automatic cache management +.IP o +ccache can cache compiler output that includes warnings\&. In many +cases this gives ccache a much higher cache hit rate\&. +.IP o +ccache can handle a much wider ranger of compiler options +.IP o +ccache avoids a double call to cpp on a cache miss +.PP +.SH "BUGS" +.PP +When the cache is stored on an NFS filesystem, the filesystem must be +exported with the \fBno_subtree_check\fP option to make renames between +directories reliable\&. +.PP +.SH "CREDITS" +.PP +Thanks to the following people for their contributions to ccache +.IP o +Erik Thiele for the original compilercache script +.IP o +Luciano Rocha for the idea of compiling the pre-processor output +to avoid a 2nd cpp pass +.IP o +Paul Russell for many suggestions and the debian packaging +.PP +.SH "AUTHOR" +.PP +ccache was written by Andrew Tridgell +http://samba\&.org/~tridge/ +.PP +If you wish to report a problem or make a suggestion then please email +bugs@ccache\&.samba\&.org +.PP +ccache is released under the GNU General Public License version 2 or +later\&.

It speeds up re-compilation of C/C++ code +by caching previous compiles and detecting when the same compile is +being done again. + +manpagesection(OPTIONS SUMMARY) + +Here is a summary of the options to ccache. + +verb( +-s show statistics summary +-z zero statistics +-c run a cache cleanup +-C clear the cache completely +-F set maximum files in cache +-M set maximum size of cache (use G, M or K) +-h this help page +-V print version number +) + +manpageoptions() + +These options only apply when you invoke ccache as "ccache". When +invoked as a compiler none of these options apply. In that case your +normal compiler options apply and you should refer to your compilers +documentation. + +startdit() +dit(bf(-h)) Print a options summary page + +dit(bf(-s)) Print the current statistics summary for the cache. The +statistics are stored spread across the subdirectories of the +cache. Using "ccache -s" adds up the statistics across all +subdirectories and prints the totals. + +dit(bf(-z)) Zero the cache statistics. + +dit(bf(-V)) Print the ccache version number + +dit(bf(-c)) Clean the cache and re-calculate the cache file count and +size totals. Normally the -c option should not be necessary as ccache +keeps the cache below the specified limits at runtime and keeps +statistics up to date on each compile. This option is mostly useful +if you manually modify the cache contents or believe that the cache +size statistics may be inaccurate. + +dit(bf(-C)) Clear the entire cache, removing all cached files. + +dit(bf(-F maxfiles)) This sets the maximum number of files allowed in +the cache. The value is stored inside the cache directory and applies +to all future compiles. Due to the way the value is stored the actual +value used is always rounded down to the nearest multiple of 16. + +dit(bf(-M maxsize)) This sets the maximum cache size. You can specify +a value in gigabytes, megabytes or kilobytes by appending a G, M or K +to the value. The default is gigabytes. The actual value stored is +rounded down to the nearest multiple of 16 kilobytes. + +enddit() + +manpagesection(INSTALLATION) + +There are two ways to use ccache. You can either prefix your compile +commands with "ccache" or you can create a symbolic link between +ccache and the names of your compilers. The first method is most +convenient if you just want to try out ccache or wish to use it for +some specific projects. The second method is most useful for when you +wish to use ccache for all your compiles. + +To install for usage by the first method just copy ccache to somewhere +in your path. + +To install for the second method do something like this: +verb( + cp ccache /usr/local/bin/ + ln -s /usr/local/bin/ccache /usr/local/bin/gcc + ln -s /usr/local/bin/ccache /usr/local/bin/g++ + ln -s /usr/local/bin/ccache /usr/local/bin/cc +) +This will work as long as /usr/local/bin comes before the path to gcc +(which is usually in /usr/bin). After installing you may wish to run +"which gcc" to make sure that the correct link is being used. + +Note! Do not use a hard link, use a symbolic link. A hardlink will +cause "interesting" problems. + +manpagesection(EXTRA OPTIONS) + +When run as a compiler front end ccache usually just takes the same +command line options as the compiler you are using. The only exception +to this is the option '--ccache-skip'. That option can be used to tell +ccache that the next option is definitely not a input filename, and +should be passed along to the compiler as-is. + +The reason this can be important is that ccache does need to parse the +command line and determine what is an input filename and what is a +compiler option, as it needs the input filename to determine the name +of the resulting object file (among other things). The heuristic +ccache uses in this parse is that any string on the command line that +exists as a file is treated as an input file name (usually a C +file). By using --ccache-skip you can force an option to not be +treated as an input file name and instead be passed along to the +compiler as a command line option. + +manpagesection(ENVIRONMENT VARIABLES) + +ccache uses a number of environment variables to control operation. In +most cases you won't need any of these as the defaults will be fine. + +startdit() + +dit(bf(CCACHE_DIR)) the CCACHE_DIR environment variable specifies +where ccache will keep its cached compiler output. The default is +"$HOME/.ccache". + +dit(bf(CCACHE_TEMPDIR)) the CCACHE_TEMPDIR environment variable specifies +where ccache will put temporary files. The default is the same as +CCACHE_DIR. Note that the CCACHE_TEMPDIR path must be on the same +filesystem as the CCACHE_DIR path, so that renames of files between +the two directories can work. + +dit(bf(CCACHE_LOGFILE)) If you set the CCACHE_LOGFILE environment +variable then ccache will write some log information on cache hits +and misses in that file. This is useful for tracking down problems. + +dit(bf(CCACHE_PATH)) You can optionally set CCACHE_PATH to a colon +separated path where ccache will look for the real compilers. If you +don't do this then ccache will look for the first executable matching +the compiler name in the normal PATH that isn't a symbolic link to +ccache itself. + +dit(bf(CCACHE_CC)) You can optionally set CCACHE_CC to force the name +of the compiler to use. If you don't do this then ccache works it out +from the command line. + +dit(bf(CCACHE_PREFIX)) This option adds a prefix to the command line +that ccache runs when invoking the compiler. Also see the section +below on using ccache with distcc. + +dit(bf(CCACHE_DISABLE)) If you set the environment variable +CCACHE_DISABLE then ccache will just call the real compiler, +bypassing the cache completely. + +dit(bf(CCACHE_READONLY)) the CCACHE_READONLY environment variable +tells ccache to attempt to use existing cached object files, but not +to try to add anything new to the cache. If you are using this because +your CCACHE_DIR is read-only, then you may find that you also need to +set CCACHE_TEMPDIR as otherwise ccache will fail to create the +temporary files. + +dit(bf(CCACHE_CPP2)) If you set the environment variable CCACHE_CPP2 +then ccache will not use the optimisation of avoiding the 2nd call to +the pre-processor by compiling the pre-processed output that was used +for finding the hash in the case of a cache miss. This is primarily a +debugging option, although it is possible that some unusual compilers +will have problems with the intermediate filename extensions used in +this optimisation, in which case this option could allow ccache to be +used. + +dit(bf(CCACHE_NOSTATS)) If you set the environment variable +CCACHE_NOSTATS then ccache will not update the statistics files on +each compile. + +dit(bf(CCACHE_NLEVELS)) The environment variable CCACHE_NLEVELS allows +you to choose the number of levels of hash in the cache directory. The +default is 2. The minimum is 1 and the maximum is 8. + +dit(bf(CCACHE_HARDLINK)) If you set the environment variable +CCACHE_HARDLINK then ccache will attempt to use hard links from the +cache directory when creating the compiler output rather than using a +file copy. Using hard links is faster, but can confuse programs like +'make' that rely on modification times. + +dit(bf(CCACHE_RECACHE)) This forces ccache to not use any cached +results, even if it finds them. New results are still cached, but +existing cache entries are ignored. + +dit(bf(CCACHE_UMASK)) This sets the umask for ccache and all child +processes (such as the compiler). This is mostly useful when you wish +to share your cache with other users. Note that this also affects the +file permissions set on the object files created from your +compilations. + +dit(bf(CCACHE_HASHDIR)) This tells ccache to hash the current working +directory when calculating the hash that is used to distinguish two +compiles. This prevents a problem with the storage of the current +working directory in the debug info of a object file, which can lead +ccache to give a cached object file that has the working directory in +the debug info set incorrectly. This option is off by default as the +incorrect setting of this debug info rarely causes problems. If you +strike problems with gdb not using the correct directory then enable +this option. + +dit(bf(CCACHE_UNIFY)) If you set the environment variable CCACHE_UNIFY +then ccache will use the C/C++ unifier when hashing the pre-processor +output if -g is not used in the compile. The unifier is slower than a +normal hash, so setting this environment variable loses a little bit +of speed, but it means that ccache can take advantage of not +recompiling when the changes to the source code consist of +reformatting only. Note that using CCACHE_UNIFY changes the hash, so +cached compiles with CCACHE_UNIFY set cannot be used when +CCACHE_UNIFY is not set and vice versa. The reason the unifier is off +by default is that it can give incorrect line number information in +compiler warning messages. + +dit(bf(CCACHE_EXTENSION)) Normally ccache tries to automatically +determine the extension to use for intermediate C pre-processor files +based on the type of file being compiled. Unfortunately this sometimes +doesn't work, for example when using the aCC compiler on HP-UX. On +systems like this you can use the CCACHE_EXTENSION option to override +the default. On HP-UX set this environment variable to "i" if you use +the aCC compiler. + +enddit() + +manpagesection(CACHE SIZE MANAGEMENT) + +By default ccache has a one gigabyte limit on the cache size and no +maximum number of files. You can set a different limit using the +"ccache -M" and "ccache -F" options, which set the size and number of +files limits. + +When these limits are reached ccache will reduce the cache to 20% +below the numbers you specified in order to avoid doing the cache +clean operation too often. + +manpagesection(HOW IT WORKS) + +The basic idea is to detect when you are compiling exactly the same +code a 2nd time and use the previously compiled output. You detect +that it is the same code by forming a hash of: + +itemize( + it() the pre-processor output from running the compiler with -E + it() the command line options + it() the real compilers size and modification time + it() any stderr output generated by the compiler +) + +These are hashed using md4 (a strong hash) and a cache file is formed +based on that hash result. When the same compilation is done a second +time ccache is able to supply the correct compiler output (including +all warnings etc) from the cache. + +ccache has been carefully written to always produce exactly the same +compiler output that you would get without the cache. If you ever +discover a case where ccache changes the output of your compiler then +please let me know. + +manpagesection(USING CCACHE WITH DISTCC) + +distcc is a very useful program for distributing compilation across a +range of compiler servers. It is often useful to combine distcc with +ccache, so that compiles that are done are sped up by distcc, but that +ccache avoids the compile completely where possible. + +To use distcc with ccache I recommend using the CCACHE_PREFIX +option. You just need to set the environment variable CCACHE_PREFIX to +'distcc' and ccache will prefix the command line used with the +compiler with the command 'distcc'. + +manpagesection(SHARING A CACHE) + +A group of developers can increase the cache hit rate by sharing a +cache directory. The hard links however cause unwanted side effects, +as all links to a cached file share the file's modification timestamp. +This results in false dependencies to be triggered by timestamp-based +build systems whenever another user links to an existing +file. Typically, users will see that their libraries and binaries are +relinked without reason. To share a cache without side effects, the +following conditions need to be met: + +itemize( + it() Use the same bf(CCACHE_DIR) environment variable setting + it() Set the bf(CCACHE_NOLINK) environment variable + it() Make sure everyone sets the CCACHE_UMASK environment variable + to 002, this ensures that cached files are accessible to everyone in + the group. + it() Make sure that all users have write permission in the entire + cache directory (and that you trust all users of the shared cache). + it() Make sure that the setgid bit is set on all directories in the + cache. This tells the filesystem to inherit group ownership for new + directories. The command "chmod g+s `find $CCACHE_DIR -type d`" might + be useful for this. +) + +manpagesection(HISTORY) + +ccache was inspired by the compilercache shell script script written +by Erik Thiele and I would like to thank him for an excellent piece of +work. See +url(http://www.erikyyy.de/compilercache/)(http://www.erikyyy.de/compilercache/) +for the Erik's scripts. + +I wrote ccache because I wanted to get a bit more speed out of a +compiler cache and I wanted to remove some of the limitations of the +shell-script version. + +manpagesection(DIFFERENCES FROM COMPILERCACHE) + +The biggest differences between Erik's compilercache script and ccache +are: +itemize( +it() ccache is written in C, which makes it a bit faster (calling out to + external programs is mostly what slowed down the scripts). +it() ccache can automatically find the real compiler +it() ccache keeps statistics on hits/misses +it() ccache can do automatic cache management +it() ccache can cache compiler output that includes warnings. In many + cases this gives ccache a much higher cache hit rate. +it() ccache can handle a much wider ranger of compiler options +it() ccache avoids a double call to cpp on a cache miss +) + +manpagesection(BUGS) + +When the cache is stored on an NFS filesystem, the filesystem must be +exported with the bf(no_subtree_check) option to make renames between +directories reliable. + +manpagesection(CREDITS) + +Thanks to the following people for their contributions to ccache +itemize( + it() Erik Thiele for the original compilercache script + it() Luciano Rocha for the idea of compiling the pre-processor output + to avoid a 2nd cpp pass + it() Paul Russell for many suggestions and the debian packaging +) + +manpageauthor() + +ccache was written by Andrew Tridgell +url(http://samba.org/~tridge/)(http://samba.org/~tridge/) + +If you wish to report a problem or make a suggestion then please email +bugs@ccache.samba.org + +ccache is released under the GNU General Public License version 2 or +later.

Don't yet + * support the exponent (e,E) and sigfig (g,G). Also, fmtint() + * was pretty badly broken, it just wasn't being exercised in ways + * which showed it, so that's been fixed. Also, formated the code + * to mutt conventions, and removed dead code left over from the + * original.

NAME

+ ccache - a fast compiler cache +

SYNOPSIS

+ +

ccache [OPTION] +

ccache <compiler> [COMPILER OPTIONS] +

<compiler> [COMPILER OPTIONS] +

DESCRIPTION

+ +

ccache is a compiler cache. It speeds up re-compilation of C/C++ code +by caching previous compiles and detecting when the same compile is +being done again. +

OPTIONS SUMMARY

+ +

Here is a summary of the options to ccache. +

+
+-s                      show statistics summary
+-z                      zero statistics
+-c                      run a cache cleanup
+-C                      clear the cache completely
+-F <maxfiles>           set maximum files in cache
+-M <maxsize>            set maximum size of cache (use G, M or K)
+-h                      this help page
+-V                      print version number
+
+
+ +

OPTIONS

+ +

These options only apply when you invoke ccache as "ccache". When +invoked as a compiler none of these options apply. In that case your +normal compiler options apply and you should refer to your compilers +documentation. +

+

-h
Print a options summary page +

-s
Print the current statistics summary for the cache. The +statistics are stored spread across the subdirectories of the +cache. Using "ccache -s" adds up the statistics across all +subdirectories and prints the totals. +

-z
Zero the cache statistics. +

-V
Print the ccache version number +

-c
Clean the cache and re-calculate the cache file count and +size totals. Normally the -c option should not be necessary as ccache +keeps the cache below the specified limits at runtime and keeps +statistics up to date on each compile. This option is mostly useful +if you manually modify the cache contents or believe that the cache +size statistics may be inaccurate. +

-C
Clear the entire cache, removing all cached files. +

-F maxfiles
This sets the maximum number of files allowed in +the cache. The value is stored inside the cache directory and applies +to all future compiles. Due to the way the value is stored the actual +value used is always rounded down to the nearest multiple of 16. +

-M maxsize
This sets the maximum cache size. You can specify +a value in gigabytes, megabytes or kilobytes by appending a G, M or K +to the value. The default is gigabytes. The actual value stored is +rounded down to the nearest multiple of 16 kilobytes. +

+

INSTALLATION

+ +

There are two ways to use ccache. You can either prefix your compile +commands with "ccache" or you can create a symbolic link between +ccache and the names of your compilers. The first method is most +convenient if you just want to try out ccache or wish to use it for +some specific projects. The second method is most useful for when you +wish to use ccache for all your compiles. +

To install for usage by the first method just copy ccache to somewhere +in your path. +

To install for the second method do something like this: +

+
+  cp ccache /usr/local/bin/
+  ln -s /usr/local/bin/ccache /usr/local/bin/gcc
+  ln -s /usr/local/bin/ccache /usr/local/bin/g++
+  ln -s /usr/local/bin/ccache /usr/local/bin/cc
+
+
+ +This will work as long as /usr/local/bin comes before the path to gcc +(which is usually in /usr/bin). After installing you may wish to run +"which gcc" to make sure that the correct link is being used. +

Note! Do not use a hard link, use a symbolic link. A hardlink will +cause "interesting" problems. +

EXTRA OPTIONS

+ +

When run as a compiler front end ccache usually just takes the same +command line options as the compiler you are using. The only exception +to this is the option '--ccache-skip'. That option can be used to tell +ccache that the next option is definitely not a input filename, and +should be passed along to the compiler as-is. +

The reason this can be important is that ccache does need to parse the +command line and determine what is an input filename and what is a +compiler option, as it needs the input filename to determine the name +of the resulting object file (among other things). The heuristic +ccache uses in this parse is that any string on the command line that +exists as a file is treated as an input file name (usually a C +file). By using --ccache-skip you can force an option to not be +treated as an input file name and instead be passed along to the +compiler as a command line option. +

ENVIRONMENT VARIABLES

+ +

ccache uses a number of environment variables to control operation. In +most cases you won't need any of these as the defaults will be fine. +

+

CCACHE_DIR
the CCACHE_DIR environment variable specifies +where ccache will keep its cached compiler output. The default is +"$HOME/.ccache". +

CCACHE_TEMPDIR
the CCACHE_TEMPDIR environment variable specifies +where ccache will put temporary files. The default is the same as +CCACHE_DIR. Note that the CCACHE_TEMPDIR path must be on the same +filesystem as the CCACHE_DIR path, so that renames of files between +the two directories can work. +

CCACHE_LOGFILE
If you set the CCACHE_LOGFILE environment +variable then ccache will write some log information on cache hits +and misses in that file. This is useful for tracking down problems. +

CCACHE_PATH
You can optionally set CCACHE_PATH to a colon +separated path where ccache will look for the real compilers. If you +don't do this then ccache will look for the first executable matching +the compiler name in the normal PATH that isn't a symbolic link to +ccache itself. +

CCACHE_CC
You can optionally set CCACHE_CC to force the name +of the compiler to use. If you don't do this then ccache works it out +from the command line. +

CCACHE_PREFIX
This option adds a prefix to the command line +that ccache runs when invoking the compiler. Also see the section +below on using ccache with distcc. +

CCACHE_DISABLE
If you set the environment variable +CCACHE_DISABLE then ccache will just call the real compiler, +bypassing the cache completely. +

CCACHE_READONLY
the CCACHE_READONLY environment variable +tells ccache to attempt to use existing cached object files, but not +to try to add anything new to the cache. If you are using this because +your CCACHE_DIR is read-only, then you may find that you also need to +set CCACHE_TEMPDIR as otherwise ccache will fail to create the +temporary files. +

CCACHE_CPP2
If you set the environment variable CCACHE_CPP2 +then ccache will not use the optimisation of avoiding the 2nd call to +the pre-processor by compiling the pre-processed output that was used +for finding the hash in the case of a cache miss. This is primarily a +debugging option, although it is possible that some unusual compilers +will have problems with the intermediate filename extensions used in +this optimisation, in which case this option could allow ccache to be +used. +

CCACHE_NOSTATS
If you set the environment variable +CCACHE_NOSTATS then ccache will not update the statistics files on +each compile. +

CCACHE_NLEVELS
The environment variable CCACHE_NLEVELS allows +you to choose the number of levels of hash in the cache directory. The +default is 2. The minimum is 1 and the maximum is 8. +

CCACHE_HARDLINK
If you set the environment variable +CCACHE_HARDLINK then ccache will attempt to use hard links from the +cache directory when creating the compiler output rather than using a +file copy. Using hard links is faster, but can confuse programs like +'make' that rely on modification times. +

CCACHE_RECACHE
This forces ccache to not use any cached +results, even if it finds them. New results are still cached, but +existing cache entries are ignored. +

CCACHE_UMASK
This sets the umask for ccache and all child +processes (such as the compiler). This is mostly useful when you wish +to share your cache with other users. Note that this also affects the +file permissions set on the object files created from your +compilations. +

CCACHE_HASHDIR
This tells ccache to hash the current working +directory when calculating the hash that is used to distinguish two +compiles. This prevents a problem with the storage of the current +working directory in the debug info of a object file, which can lead +ccache to give a cached object file that has the working directory in +the debug info set incorrectly. This option is off by default as the +incorrect setting of this debug info rarely causes problems. If you +strike problems with gdb not using the correct directory then enable +this option. +

CCACHE_UNIFY
If you set the environment variable CCACHE_UNIFY +then ccache will use the C/C++ unifier when hashing the pre-processor +output if -g is not used in the compile. The unifier is slower than a +normal hash, so setting this environment variable loses a little bit +of speed, but it means that ccache can take advantage of not +recompiling when the changes to the source code consist of +reformatting only. Note that using CCACHE_UNIFY changes the hash, so +cached compiles with CCACHE_UNIFY set cannot be used when +CCACHE_UNIFY is not set and vice versa. The reason the unifier is off +by default is that it can give incorrect line number information in +compiler warning messages. +

CCACHE_EXTENSION
Normally ccache tries to automatically +determine the extension to use for intermediate C pre-processor files +based on the type of file being compiled. Unfortunately this sometimes +doesn't work, for example when using the aCC compiler on HP-UX. On +systems like this you can use the CCACHE_EXTENSION option to override +the default. On HP-UX set this environment variable to "i" if you use +the aCC compiler. +

+

CACHE SIZE MANAGEMENT

+ +

By default ccache has a one gigabyte limit on the cache size and no +maximum number of files. You can set a different limit using the +"ccache -M" and "ccache -F" options, which set the size and number of +files limits. +

When these limits are reached ccache will reduce the cache to 20% +below the numbers you specified in order to avoid doing the cache +clean operation too often. +

HOW IT WORKS

+ +

The basic idea is to detect when you are compiling exactly the same +code a 2nd time and use the previously compiled output. You detect +that it is the same code by forming a hash of: +

    +
  • the pre-processor output from running the compiler with -E +
  • the command line options +
  • the real compilers size and modification time +
  • any stderr output generated by the compiler +
+

These are hashed using md4 (a strong hash) and a cache file is formed +based on that hash result. When the same compilation is done a second +time ccache is able to supply the correct compiler output (including +all warnings etc) from the cache. +

ccache has been carefully written to always produce exactly the same +compiler output that you would get without the cache. If you ever +discover a case where ccache changes the output of your compiler then +please let me know. +

USING CCACHE WITH DISTCC

distcc is a very useful program for distributing compilation across a +range of compiler servers. It is often useful to combine distcc with +ccache, so that compiles that are done are sped up by distcc, but that +ccache avoids the compile completely where possible. +

To use distcc with ccache I recommend using the CCACHE_PREFIX +option. You just need to set the environment variable CCACHE_PREFIX to +'distcc' and ccache will prefix the command line used with the +compiler with the command 'distcc'. +

SHARING A CACHE

+ +

A group of developers can increase the cache hit rate by sharing a +cache directory. The hard links however cause unwanted side effects, +as all links to a cached file share the file's modification timestamp. +This results in false dependencies to be triggered by timestamp-based +build systems whenever another user links to an existing +file. Typically, users will see that their libraries and binaries are +relinked without reason. To share a cache without side effects, the +following conditions need to be met: +

    +
  • Use the same CCACHE_DIR environment variable setting +
  • Set the CCACHE_NOLINK environment variable +
  • Make sure everyone sets the CCACHE_UMASK environment variable + to 002, this ensures that cached files are accessible to everyone in + the group. +
  • Make sure that all users have write permission in the entire + cache directory (and that you trust all users of the shared cache). +
  • Make sure that the setgid bit is set on all directories in the + cache. This tells the filesystem to inherit group ownership for new + directories. The command "chmod g+s `find $CCACHE_DIR -type d`" might + be useful for this. +
+

HISTORY

+ +

ccache was inspired by the compilercache shell script script written +by Erik Thiele and I would like to thank him for an excellent piece of +work. See +http://www.erikyyy.de/compilercache/ +for the Erik's scripts. +

I wrote ccache because I wanted to get a bit more speed out of a +compiler cache and I wanted to remove some of the limitations of the +shell-script version. +

DIFFERENCES FROM COMPILERCACHE

+ +

The biggest differences between Erik's compilercache script and ccache +are: +

    +
  • ccache is written in C, which makes it a bit faster (calling out to + external programs is mostly what slowed down the scripts). +
  • ccache can automatically find the real compiler +
  • ccache keeps statistics on hits/misses +
  • ccache can do automatic cache management +
  • ccache can cache compiler output that includes warnings. In many + cases this gives ccache a much higher cache hit rate. +
  • ccache can handle a much wider ranger of compiler options +
  • ccache avoids a double call to cpp on a cache miss +
+

BUGS

+ +

When the cache is stored on an NFS filesystem, the filesystem must be +exported with the no_subtree_check option to make renames between +directories reliable. +

ccache

+ +ccache is a compiler cache. It acts as a caching pre-processor to +C/C++ compilers, using the -E compiler switch and a hash to detect +when a compilation can be satisfied from cache. This often results in +a 5 to 10 times speedup in common compilations.

+ +The idea came from Erik Thiele wrote the original compilercache program +as a bourne shell script. ccache is a re-implementation of Erik's idea +in C with more features and better performance.

+ +

Latest release

+ +The latest release is ccache 2.4. + +
    +
  • Added CCACHE_READONLY option +
  • Added CCACHE_TEMPDIR option +
  • fixed handling of hard-linked compilers on AIX +
  • added O_BINARY support, to try and support win32 compiles +
  • show cache directory in stats output +
  • fixed handling of HOME environment variable +
+ +See the manual page for details +on the new options.

+ +You can get this release from the download directory + +

NOTE! This release changes the hash input slighly, so you will +probably find that you will not get any hits against your existing +cache when you upgrade. + +

Why bother?

+ +Why bother with a compiler cache? If you ever run "make clean; make" +then you can probably benefit from ccache. It is very common for +developers to do a clean build of a project for a whole host of +reasons, and this throws away all the information from your previous +compiles.

+ +By using ccache you can get exactly the same effect as "make clean; +make" but much faster. It also helps a lot when doing RPM builds, +as RPM can make doing incremental builds tricky.

+ +I put the effort into writing ccache for 2 reasons. The first is the +Samba build farm +(http://build.samba.org/) +which constantly does clean builds of Samba on about 30 machines after each +CVS commit. On some of those machines the build took over an hour. By +using ccache we get the same effect as clean builds but about 6 times +faster.

+ +The second reason is the autobuild system I used to run for +Quantum. That system builds our whole Linux based OS from scratch +after every CVS commit to catch compilation problems quickly. Using +ccache those builds are much faster. + +

Is it safe?

+ +Yes. The most important aspect of a compiler cache is to always +produce exactly the same output that the real compiler would +produce. The includes providing exactly the same object files and +exactly the same compiler warnings that would be produced if you use +the real compiler. The only way you should be able to tell that you +are using ccache is the speed.

+ +I have coded ccache very carefully to try to provide these guarantees. + +

Features

+ +
    +
  • keeps statistics on hits/misses +
  • automatic cache size management +
  • can cache compiles that generate warnings +
  • easy installation +
  • very low overhead +
  • uses hard links where possible to avoid copies +
+ +

How to use it

+ +You can use ccache in two ways. The first is just to prefix your +compile commands with "ccache". For example, you could change the +"CC=gcc" line in your Makefile to be "CC=ccache gcc".

+ +Alternatively, you can create symbolic links from your compilers name +to ccache. This allows you to use ccache without any changes to your +build system. + +

Download

+ +You can download the latest release from the download directory.

+ +For the bleeding edge, you can fetch ccache via CVS or +rsync. To fetch via cvs use the following command: + +

+  cvs -d :pserver:cvs@pserver.samba.org:/cvsroot co ccache
+
+ +To fetch via rsync use this command: + +
+  rsync -Pavz samba.org::ftp/unpacked/ccache .
