Maybe a stupid question, but I was wondering where Python's distutils get the compiler options from? It gets some linked directories wrong and I want to correct that once and for all.
I know there should be a prefix/lib/pythonver/distutils/distutils.cfg but I can't find any distutils.cfg anywhere on the computer. Obviously I haven't got a local setup.cfg or any $HOME/.pydistutils.cfg.
I'm using the Enthought 64-bit distribution, version 7.3 (Python 2.7) on Mac OS X 10.8.3
Cheers, U.
I actually export them to the environment, just like for autotools' configure:
export CC=/usr/local/bin/clang
export CFLAGS=-I${HOME}/include
export LDFLAGS=-lboost
If you also need to override the linker separately:
export LDSHARED=/usr/local/bin/clang -shared
And if you don't like exporting the settings to your environment, do something like this for a one-time setting:
CC=/usr/local/bin/clang CFLAGS=-I${HOME}/include python setup.py build
If you want to find out what the default options were when python was build, use python-config --<flag>. Some flags are cflags, ldflags, libs or includes.
Compiler options are taken from CPython’s Makefile. IOW they are the same as the ones used to compile Python. You can override most of them on the command line as Evert described.
The global distutils.cfg is something that a sysadmin can create to set default options, not a file that is installed with Python.
