Thanks! That did fix the Gtk::Window problem... now I get this error:
g++ -Wall -c -g `pkg-config --cflags gtkmm-2.4` -o foo.o foo.cpp
foo.h:13: error: 'Glib' has not been declared
foo.h:13: error: ISO C++ forbids declaration of 'RefPtr' with no type
foo.h:13: error: expected ';' before '<' token
make: *** [foo.o] Error 1
But it works if I replace the original includes with:
#include <glibmm/refptr.h>
Is this the minimum set of header dependencies since
the compiler needs to know that a RefPtr is a pointer?
That header is 342 lines, which is a bit bigger than I'd
like. Any way to avoid refptr.h inclusion?
Thanks,
David
