You should use pkg-config to set the include dirs, instead of doing it
by hand (for example, you don't currently have the include dirs for
gdkmm, pangomm, cairomm, glibmm, etc, etc).  In addition, you're not
specifying which libraries to link against.  Thirdly, you're using gcc
but you should be using g++ since you're attempting to compile C++.
So your command should look something like:

g++ main.cpp `pkg-config --libs --cflags gtkmm-2.4` -o main
