Hi.

I'm really struggling getting Math::Pari to build in Activeperl. I've installed a C Compiler and I'm at the point where cl.exe runs OK once I have set the environment variables correctly. This is how I did it:

Free MSVC tools + Activestate to compile CPAN Modules

 The only step I didn't follow was to install the SDK update because I can't get on the website at the moment. I don't think this is the problem but if anyone knows different please let me know.

Apparently Math::Pari requires the GP/PARI build directory. I don't really know what GP/PARI is, but I've installed the pari-2.1.6 directory plus the cygwin1.dll and gp-2-1-1.exe file as described in the readme file for Windows.

I've looked through quite a bit of documentation but the compilation of Math::Pari is still failing with the following error:

../../pari-2.1.6\src\gp\highlvl.c(77) : fatal error C1083: Cannot open include file: 'windows.h': No such file or directory.

This looks like a pretty fundamental problem to me, but I've no idea how to fix it. Can anyone help?

Thanks.
