Hi Neil,
If your using Linux then you have to install the glib RPM's in the usual
way. I don't know about other platforms, but I am sure there will be a
version of glib out there...
Also ensure the correct include and link directives are in your
Makefile, which you can get (on Linux) using the commands:
# glib-config --cflags
# glib-config --libs
