I haven't been able to find an easy answer to this question, but here is my problem:
Cython file: extension.pyx Declarations / C imports: extension.pxd C dependencies: a.c b.c c.c
These are all compiled together to produce extension.so.
The problem is, when I modify extension.pyx, all 4 C files are recompiled, even if the 3 straight C files are untouched.
Any way to fix the build system to not do this? Seems that the .o files from the C dependencies could be easily reused.
Cython compiles the .pyx file to a .c file; distutils takes over from there. I'm not aware of any way to do this (short of making a+b+c into a shared library) but perhaps someone on the distutils lists would have some ideas.
You could also look at using ccache.

Using ccache and patching distutils as described in this SO post was adequate for my needs: http://stackoverflow.com/questions/11013851/speeding-up-build-process-with-d... thanks!
