Hi,
I want to run a few C code inside Python on Windows 7, 64-bit PC, Canopy
1.5.2.2785. I made a few trials, but I forget the detail commands I made on
compiler setting. One thing I remember is that I added one file: distutils.cfg,
whose content is: [build]
compiler=mingw32
And another thing I did was an option to msvc for the compiler, but I don't
remember where the file was.
Now, it always search for 'msvccompiler', though I think it should use mingw32,
as the following:
import scipy.weave
In [16]: weave.test()

How can I set correctly to use inline C code?
