- Examples/Makefile.in rules use SRCDIR as the relative source directory - ./config.status replicates Examples/ source directory tree in build directory, and copies each Makefile to build directory, prefixed with a header which sets SRCDIR to source directory - Examples/test-suite/.../Makefile.in set SRCDIR from Autoconf-set srcdir - Examples/test-suite/errors/Makefile.in needs to filter out source directory from SWIG error messages - Lua: embedded interpreters are passed location of run-time test - Python: copy run-time scripts to build directory because of 2to3 conversion; import_packages example copies __init__.py from source directory; test-suite sets SCRIPTDIR to location of run-time tests - Javascript: binding.gyp renamed to binding.gyp.in so that $srcdir can be substituted with SRCDIR; removed './' from require() statements so that NODE_PATH can be used to point Node.js to build directory
