Well, that's certainly mystifying. pixmap.h was generated correctly, and
everything compiles, you just get crash and burn at link time. It looks
almost like your linker doesn't understand what to do when the same
template is instantiated in two files. What compiler is this? I have to
say I don't know what would cause the error other than compiler weirdness. 
Maybe someone with more knowledge can help.

Your link line here looks exactly like mine, only I get no errors:

Sorry I'm not more helpful...
