llvmpy: Python bindings for LLVM
================================
Home page
---------
http://www.llvmpy.org
Versions
--------
This package has been tested with LLVM 3.2, Python 2.6, 2.7 and 3.3.
Other Python versions may work.
Quickstart
----------
1. Get and extract LLVM 3.2 source tarball from
`llvm.org <http://llvm.org/releases/download.html#3.2>`_. Then, ``cd`` into
the extracted directory.
2. Run ``./configure --enable-optimized --prefix=LLVM_INSTALL_PATH``.
**Note**: Without the ``--enable-optimized`` flag, debug build will be
selected. Unless you are developing LLVM or llvmpy, it is recommended
that the flag is used to reduce build time and binary size.
**Note**: Use prefix to select the installation path. It is recommended
to separate your custom build from the default system package. Please
replace ``LLVM_INSTALL_PATH`` with your own path.
3. Run ``REQUIRES_RTTI=1 make`` to build.
**Note**: With LLVM 3.2, the default build configuration has C++ RTTI
disabled. However, llvmpy requires RTTI.
4. Get llvm-py and install it::
$ git clone git@github.com:llvmpy/llvmpy.git
$ cd llvmpy
$ LLVM_CONFIG_PATH=LLVM_INSTALL_PATH/bin/llvm-config python setup.py install
Run the tests::
$ python -c "import llvm; llvm.test()"
5. See documentation at 'http://www.llvmpy.org' and examples
under 'test'.
Common Build Problems
---------------------
1. If llvmpy cannot be imported due to "undefined symbol:
_ZTIN4llvm24PassRegistrationListenerE", it is because RTTI is not enabled
when building LLVM. "_ZTIN4llvm24PassRegistrationListenerE" is the typeinfo
of PassRegistrationListener class.
