Hi chuckd,

You're using Visual Studio 9.0 ? I didn't even know such a beast existed.

Do you actually have a header file called sdkddkver.h ? (If so, where is it located ?) None of the windows.h files that I have on my machines make any attempt to include such a file.

Usually, with Visual Studio, there's a vcvars32.bat that one runs to set up the correct environment variables. Does Visual Studio 9.0 come with that file ? If so, does running that file solve anything for you.

Bear in mind that ActivePerl (which I'm assuming, in the absence of contrary evidence, is what you're using) was built using Visual Studio 6.0 - and there's a potential for incompatibility problems if you start using Visual Studio 9.0 with ActivePerl. (Better, imo, to use MinGW with ActivePerl ... or use instead Strawberry Perl, which ships with the MinGW compiler.)

If none of this helps, could you please provide the output of running perl -V .

Cheers,
Rob
