OK, I've reproduced this, and I can't get P4Perl to build with ActivePerl 
5.8.8 and VS 2005 either. Using the Perforce API at:


resolves the build errors, but then you hit runtime loading errors which, I 
think, have to do with incompatibilities between the version of Visual Studio 
used to compile Perl and the version used for P4Perl. Microsoft's C Runtime 
problems basically.

Do you need to build it yourself Dan, or can you just use the pre-built 
installer? The precompiled installer for the development build is compatible 
with ActivePerl 5.8.8 (it's compiled with Visual Studio 2003). If you want to 
compile it yourself, I suspect you'll need to use VS 2003.
