First problem was that I needed to remove your "TODO ..." comments from the XS file. I thought the same would be necessary if you were using Module::Build. And then I couldn't see any reference to the GD header or library in Build.pl, though I expected that would need to be specified, too. Did 'PHPFilter.so' actually get built for you ? It didn't for me, though I think I gave it every chance of succeeding. Sticking point for me was that `gdImageGrayScale' could not be resolved - so the build process failed at the 'make' stage. Where is that symbol defined ? it's not in my version (2.0.33) of GD. When I tried to build using your source "straight out of the box" with Module::Build, the shared object did not get built for the very same reason. It strikes me as a bug in Module::Build that the 'test' phase could then be run .... but, like I said, I don't use Module::Build ... and I know little about it (or its quirks and limitations :-) Cheers, Rob
