For that to work, you have to use -I/usr/include/gtk-2.0 to the compiler, however that should work automatically by using pkg-config. See the output of this command: $ pkg-config --cflags gtk+-2.0 -I/usr/include/gtk-2.0 -I/usr/lib64/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -I/usr/include/freetype2 -I/usr/include/libpng12 "configure" should be using that automatically, for some reason it does not appear to be doing that correctly... It might be using a string other than "gtk+-2.0" to pass to pkg-config, you could check that... You could also try to manually override it by passing CFLAGS and LDFLAGS variables to configure using pkg-config to include gtk+-2.0 yourself. That can be done with something like: $ CFLAGS=`pkg-config --cflags gtk+-2.0` LDFLAGS=`pkg-config --libs gtk+-2.0` ./configure ... And "./configure --help" might have more details on what else you can do to specify where gtk+ is installed on your system... HTH, Filipe
