Yes, gmmproc must know about the C function so that it can convert C++
parameters to the appropriate C parameters and back.

Look at one of the existing projects. You need to create the .defs
files. There is a little about this at the end of this file:
http://cvs.gnome.org/viewcvs/glibmm/docs/internal/using_gmmproc.txt?view=markup

It will be easier if you copy the build files of an existing project.
