Perhaps you should add the directory containing `gtk+-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-2.0' found
configure: error: nabi needs GTK+ 2.2.0 or higher

There are 2 locations for pkg-config files
/usr/lib/pkgconfig/
and
/usr/local/lib/pkgconfig/

Quick fix.. copy the files in /usr/local/lib/pkgconfig/ to /usr/lib/pkconfig/
That's in case you actually have gtk with that version or above installed.

Run:
pkg-config --list-all
GTK should show up now.

[root@localhost root]# gcc -Wall -g pixmap1.c -o pixmap `pkg-config --cflags
> gtk+-2.0` `pkg-config --libs gtk+-2.0`
Must specify package names on the command line
bash: gtk+-2.0: command not found
