   OK, some progress here. I have two questions: 1) Let's forget about the Intel compiler(s) for the moment and focus on a standard Windows build. Python 2.6 comes with two classes in distutils: msvccompiler.py and msvc9compiler.py. In reading through these, it appears msvc9compiler.py is ideally suited for what I'm trying to do (use VS 2008 tools). Is it possible to select this via command line flags with config --compiler=xxx? Choosing "msvc" seems to go for msvccompiler.py (I'm just tyring to trace the magic as things build). 2) when using the standard msvc setup, things do seem to work re: setting up the build environemnt (see below). Now, the VS compiler kicks out a syntax error (output copied below). Any thoughts? This looks like a peculiarity of the VS compiler but I'm not sure. (I tend to prefer the Intel C compiler because it is more "Linux-like" and seems to be happier with cross-platform code.)

   Thanks,
   ~Mike C.

The problem is that distutils does not abstract this kind of things:
you have a CCompiler class, and a subclass Unix C Compiler, and then
Intel Compiler. OTOH, the MS compiler is its own class which inherit
from CCompiler - all windows specifics are encoded in this class. So I
am afraid you will need to recreate all this class implementation for
Intel C Compiler, because contrary to the Linux case, nothing is
abstracted for windows.

With mingw compiler.

If you can build numpy with the Intel compiler, building the installer
should be a no-brainer.

cheers,
