All I meant by that was that the full path and filename of your Python3
interpreter was C:\Python31\python.exe (the .exe  isn't necessary but is part
of the filename.)

By default on Windoze python will try to use the Microsoft compilers and the
error message above is saying it can't find them.

When you say you "do have one" I'm assuming that when you entered gcc at the
command line you got the "gcc: no input files" error message back. In this case
we need to tell python to use the gcc compilers.

In Python 2.5 you can do this by creating a text file called distutils.cfg in
the C:\Python31\Lib\distutils directory with the following statements:

[build]
compiler=mingw32

[config]
compiler = mingw32

I don't have Python 3 so not sure if this still works.

HTH,
Dave
