使用Cygwin在Windows上编译Python扩展

Question

I have been having a terrible time trying to compile a python extension - hopefully someone can help.

I initially tried executing 'python.exe setup.py build' but received the error: 'Python was built Visual Studio 2003; extensions must be built with a compiler that can generate compatible binaries...".

So I then downloaded Cygwin, and have tried sending the switch '-c mingw32'. A few lines were written into the console - then I get the error message: command 'gcc' failed: Permission denied.

I was initially using the Visual Studio 2010 Command Line to do this, but tried with bash and got the same result.

I have spent a considerable amount of time researching the issue, and it appears Cygwin uses symlinks for gcc and g++, and windows doesn't understand how to handle this.

How exactly can I force setup.py to use gcc-3.exe instead of the gcc.exe symlink?

I know it's inelegant, but you can rename the symlink and copy gcc-3.exe to gcc.exe. That worked for me when I used Cygwin's gcc. You might want to switch to the mingw64-i686 (or mingw64-x86_64) package to get gcc 4.5.3, or just install MinGW-w64 separately for compiling under Windows.

Also, you can permanently configure distuilts in PythonXX\\Lib\\distutils\\distutils.cfg:

[build]
compiler = mingw32

[build_ext]
compiler = mingw32

[build_clib]
compiler = mingw32
