[Dev-C++] GTK can't compile

[Ricky <sto...@si...>]

I download Dev-C++ today. And also download the new packman, imaglib,
i18n, gtk-2.0. After I install them by packman, and try to compile even
the template program comes from New | Project, Dev-C++ can't find gtk
library and give 28 errors.

I am new to dev-c++, could any give me some detail steps to configure
gtk 2.0 on dev-c++?
I need to program GUI program using GTK in Win32 system, I need it
deeply.

Thanks for any help!!
