Couldn't link my app with GTK+ 3

OS: Fedora 14 x86_64
GCC: 4.5.1 20100924

I have a app project, use GTK+2.
I want to move it to GTK+3.
So I git clone latest glib.
Compiled them.
(I use GTK3 in mirror, not compile by myself)
(Point to GTK+3 in Makefile)
GCC Prints:
* CCLD gkiu
*
/usr/lib/gcc/x86_64-redhat-linux/4.5.1/../../../../lib64/libgtk-x11-3.0.so:

May be I must to compile latest GTK+ by myself?

(Sorry for my poor English.)
