Hi Allen,

It looks like you're not passing the required libs to gcc, somewhere
in your build scripts you'll need a line like:

i686-pc-mingw32-pkg-config gtk+-2.0 --cflags --libs

How are you building your project: using Makefiles, autotools, or
something else? Check step 5 of the tutorial:

http://mingw-cross-env.nongnu.org/#tutorial

for some common build systems, and take a look at the way the test
program is built using gcc & pkg-config, starting on line 46:

http://hg.savannah.gnu.org/hgweb/mingw-cross-env/raw-file/dd957bc0a7f7/src/gtk2.mk

These should point you in the direction.

Cheers,

Tony
