Change your CFLAGS to:

CFLAGS= -Wall -g `pkg-config gtkmm-2.0 --cflags`

If you use --libs as well, you import the linker flags, which gcc 
doesn't really like when you're not linking anything - as the messages 
you posted indicate. They're also completely unnecessary when compiling 
the object files - you just need the cflags for that.
