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@${XORG_PREFIX}@g" setup.py && patch -Np1 -i ../Python-2.7.8-gdbm-1.patch && ./configure --prefix=/usr --enable-shared && make EXTRA_CFLAGS="-fwrapv"
Install the package
make install
Command Explanations
--enable-shared: Enables the building of shared libraries.
-fwrapv: This flag is used to make it so that make test can find the python libraries and so that make install doesn't fail. Why this fixes the problem is unknown. According to GCC, -fwrapv "instructs the compiler to assume that signed arithmetic overflow of addition, subtraction and multiplication wraps around using twos-complement representation."
Multilib
32Bit
Compile the package:
sed -i "s@/usr/X11R6@${XORG_PREFIX}@g" setup.py && patch -Np1 -i ../Python-2.7.8-gdbm-1.patch && CC="gcc ${BUILD32}" CXX="g++ ${BUILD32}" ./configure --prefix=/usr \ --enable-shared && make EXTRA_CFLAGS="-fwrapv"
Install the package
make install && mv -v /usr/bin/python{,-32} && mv -v /usr/bin/python2.7{,-32} && rm -v /usr/bin/python-config && mv -v /usr/bin/python2.7-config{,-32} && mv -v /usr/include/python2.7/pyconfig{,-32}.h
N32
Change the libdir that Python is going to use to lib32:
patch -Np1 -i ../Python-2.7.8-multilib-1.patch sed -i -e "s:@@MULTILIB_DIR@@:lib32:g" \ Lib/distutils/command/install.py \ Lib/distutils/sysconfig.py \ Lib/site.py \ Makefile.pre.in \ Modules/Setup.dist \ Modules/getpath.c \ setup.py
Compile the package:
sed -i "s@/usr/X11R6@${XORG_PREFIX}@g" setup.py && patch -Np1 -i ../Python-2.7.8-gdbm-1.patch && CC="gcc ${BUILDN32}" CXX="g++ ${BUILDN32}" ./configure --prefix=/usr \ --libdir=/usr/lib32 --enable-shared && make EXTRA_CFLAGS="-fwrapv"
Install the package
make install && mv -v /usr/bin/python{,-n32} && mv -v /usr/bin/python2.7{,-n32} && rm -v /usr/bin/python-config && mv -v /usr/bin/python2.7-config{,-n32} && mv -v /usr/include/python2.7/pyconfig{,-n32}.h
64Bit
Change the libdir that Python is going to use to lib64:
patch -Np1 -i ../Python-2.7.8-multilib-1.patch sed -i -e "s:@@MULTILIB_DIR@@:lib64:g" \ Lib/distutils/command/install.py \ Lib/distutils/sysconfig.py \ Lib/site.py \ Makefile.pre.in \ Modules/Setup.dist \ Modules/getpath.c \ setup.py
Compile the package:
sed -i "s@/usr/X11R6@${XORG_PREFIX}@g" setup.py && patch -Np1 -i ../Python-2.7.8-gdbm-1.patch && CC="gcc ${BUILD64}" CXX="g++ ${BUILD64}" ./configure --prefix=/usr \ --libdir=/usr/lib64 --enable-shared && make EXTRA_CFLAGS="-fwrapv"
Install the package
make install && mv -v /usr/bin/python{,-64} && mv -v /usr/bin/python2.7{,-64} && rm -v /usr/bin/python-config && mv -v /usr/bin/python2.7-config{,-64} && ln -sfv multiarch_wrapper /usr/bin/python && ln -sfv multiarch_wrapper /usr/bin/python2.7 && ln -sfv multiarch_wrapper /usr/bin/python2.7-config ln -sfv /usr/bin/python2.7-config /usr/bin/python-config mv -v /usr/include/python2.7/pyconfig{,-64}.h
