[SciPy-user] weave and compiler

[Barry Drake]

This is my first time using weave.
OS: Win XP pro
Compilers: MS VS.Net, Enthought MingW32 distro with
gcc 3.2

I haven't found a way to force weave to use mingw32
rather that msvc.  Is there a configuration setting or
command line arg I can use?  I've checked:
platform_info.py
ext_tools.py
build_tools.py

It appears that on Windows if MSVS is installed weave
and distutils always default to the MS compiler.

In the fibonacci.py example code, I change the line:
    mod = ext_tools.ext_module('fibonacci_ext')

to
    mod = ext_tools.ext_module('fibonacci_ext',
'mingw32')

without success.  Here is the output:

distutils.errors.DistutilsPlatformError: Python was
built with version 6 of Visual Studio, and extensions
need to be built with the same version of the
compiler, but it isn't installed.

How can I force the use of a different compiler?

Thanks.
