Hi!

This says that the GraphParser class -- which you apparently defined in namespace boost; naughty, naughty! -- has an operator() with a
Well, the GraphParser-class is placed in adjacency_list_io within the namespace boost, that wasn't me.
locally-defined type State, and you're trying to pass an instance of that type off to a function template.
It's a rule of C++ that you can't instantiate templates on function-local types.
Oh, as I have learned template-stuff by doing it and not reading a book (which I probably should have), I'm actually not that familiar with this. In short: I don't understand neither the problem nor do I know how to fix it.
Learning to read your compiler's error messages can be difficult, but it is well worth the effort. STLFilt can help to make them more approachable (http://www.bdsoft.com)
Well, I looked there, but STLFilt doesn't support g++ 4.0 (to be exact: g++-4.0 (GCC) 4.0.2 20050808 (prerelease) (Ubuntu 4.0.1-4ubuntu9)). And gcc-3.3 (and 3.4) DOES compile my code without any complaints. Any other ideas? Sebastian
HTH,
