Introduction to Python
Python is a dynamic object-oriented programming language that can be used for many kinds of software development. It offers strong support for integration with other languages and tools, comes with extensive standard libraries, and can be learned in a few days. Many Python programmers report substantial productivity gains and feel the language encourages the development of higher quality, more maintainable code.

Dependencies
Optional
Non-Multilib
Compile the package:
sed -i "s@/usr/X11R6@${XORG_PREFIX}@g" setup.py && ./configure --prefix=/usr --enable-shared && make
Install the package
make install
Command Explanations
--enable-shared: Enables the building of shared libraries.
Multilib
32Bit
Compile the package:
sed -i "s@/usr/X11R6@${XORG_PREFIX}@g" setup.py && sed -i 's@/lib64@/lib@g' Modules/_ctypes/libffi/m4/libtool.m4 \ Modules/_ctypes/libffi/configure setup.py && sed -i "s/'lib64'/'lib'/g" setup.py && CC="gcc ${BUILD32}" CXX="g++ ${BUILD32}" ./configure --prefix=/usr \ --enable-shared && make
Install the package
make install && mv -v /usr/bin/python{,-32} && mv -v /usr/bin/python2{,-32} && mv -v /usr/bin/python2.7{,-32} && mv -v /usr/include/python2.7/pyconfig{,-32}.h && ln -sfv python2.7-32 /usr/bin/python2-32 && ln -sfv python2-32 /usr/bin/python-32
N32
Change the libdir that Python is going to use to lib32:
patch -Np1 -i ../Python-2.7.8-multilib-1.patch && sed -i -e "s|@@MULTILIB_DIR@@|/lib32|g" Lib/distutils/command/install.py \ Lib/distutils/sysconfig.py \ Lib/pydoc.py \ Lib/site.py \ Lib/sysconfig.py \ Lib/test/test_dl.py \ Lib/test/test_site.py \ Lib/trace.py \ Makefile.pre.in \ Modules/getpath.c \ setup.py
Compile the package:
sed -i "s@/usr/X11R6@${XORG_PREFIX}@g" setup.py && sed -i 's@/lib64@/lib32@g' Modules/_ctypes/libffi/m4/libtool.m4 \ Modules/_ctypes/libffi/configure setup.py && sed -i "s/'lib64'/'lib32'/g" setup.py && CC="gcc ${BUILDN32}" CXX="g++ ${BUILDN32}" ./configure --prefix=/usr \ --libdir=/usr/lib32 --enable-shared && make
Install the package
make install && mv -v /usr/bin/python{,-n32} && mv -v /usr/bin/python2{,-n32} && mv -v /usr/bin/python2.7{,-n32} && mv -v /usr/include/python2.7/pyconfig{,-n32}.h && ln -sfv python2.7-n32 /usr/bin/python2-n32 && ln -sfv python2-n32 /usr/bin/python-n32
64Bit
Change the libdir that Python is going to use to lib64:
patch -Np1 -i ../Python-2.7.8-multilib-1.patch && sed -i -e "s|@@MULTILIB_DIR@@|/lib64|g" Lib/distutils/command/install.py \ Lib/distutils/sysconfig.py \ Lib/pydoc.py \ Lib/site.py \ Lib/sysconfig.py \ Lib/test/test_dl.py \ Lib/test/test_site.py \ Lib/trace.py \ Makefile.pre.in \ Modules/getpath.c \ setup.py
Compile the package:
sed -i "s@/usr/X11R6@${XORG_PREFIX}@g" setup.py && CC="gcc ${BUILD64}" CXX="g++ ${BUILD64}" ./configure --prefix=/usr \ --libdir=/usr/lib64 --enable-shared && make
Remark
- sed on Modules/getpath.c did not work for me, had to add
sed -i 's@lib/python@lib64/python@g' Modules/getpath.c
- Needed additional explicit export before configure:
export USE_ARCH=64
- Needed LDFLAGS making the call to configure look like this:
CC="gcc ${BUILD64}" CXX="g++ ${BUILD64}" LDFLAGS="-L/usr/lib64" \ ./configure --prefix=/usr --libdir=/usr/lib64 --enable-shared
- Needed EXTRA_CFLAGS for make:
make EXTRA_CFLAGS="-fwrapv"
Remark ends
Install the package
make install && mv -v /usr/bin/python{,-64} && mv -v /usr/bin/python2{,-64} && mv -v /usr/bin/python2.7{,-64} && ln -sfv python2.7-64 /usr/bin/python2-64 && ln -sfv python2-64 /usr/bin/python-64 && ln -sfv multiarch_wrapper /usr/bin/python && ln -sfv multiarch_wrapper /usr/bin/python2 && ln -sfv multiarch_wrapper /usr/bin/python2.7 && mv -v /usr/include/python2.7/pyconfig{,-64}.h
