GTK+, or the GIMP Toolkit, is a multi-platform toolkit for creating graphical user interfaces. Offering a complete set of widgets. GTK+ is suitable for projects ranging from small one-off tools to complete application suites.

With scratchbox2 and qemu on the host machine cross compiling was straightforward.
Cross compiling order
1) tslib
sb2 ./configure --prefix=/opt/gtkfb
sb2 make install
2) zlib
since glib require zlib
sb2 ./configure --prefix=/opt/gtkfb --shared
sb2 make install
3) glib
LDFLAGS=-L/opt/gtkfb/lib CPPFLAGS=-I/opt/gtkfb/include/ sb2 ./configure --prefix=/opt/gtkfb --disable-static --with-html-dir=/tmp/dump
sb2 make install
4) atk
export PKG_CONFIG_PATH=/opt/gtkfb/lib/pkgconfig
LDFLAGS=-L/opt/gtkfb/lib CPPFLAGS=-I/opt/gtkfb/include/ sb2 ./configure --prefix=/opt/gtkfb --disable-glibtest
sb2 make install
5) jpeg-8b
sb2 ./configure --prefix=/opt/gtkfb --enable-shared --enable-static
sb2 make install
6) libpng
LDFLAGS=-L/opt/gtkfb/lib CPPFLAGS=-I/opt/gtkfb/include/ sb2 ./configure --prefix=/opt/gtkfb
sb2 make install
7) expat-2.0
sb2 ./configure --prefix=/opt/gtkfb
sb2 make install
8) freetype
sb2 ./configure --prefix=/opt/gtkfb
sb2 make install
9)libxml
LDFLAGS=-L/opt/arm/gst/lib CPPFLAGS=-I/opt/arm/gst/include/ sb2 ./configure --prefix=/opt/gtkfb --without-python
sb2 make install
10)freetype-2.3.12
LDFLAGS=-L/opt/arm/gst/lib CPPFLAGS=-I/opt/arm/gst/include/ sb2 ./configure --prefix=/opt/gtkfb --with-freetype-config=/opt/gtkfb/bin/freetype-config
11) tiff -- not used gcc 4.3.2
LDFLAGS=-L/opt/arm/gst/lib CPPFLAGS=-I/opt/arm/gst/include/ sb2 ./configure --prefix=/opt/gtkfb --enable-shared
sb2 make install
12) DirectFB
LDFLAGS=-L/opt/arm/gst/lib CPPFLAGS=-I/opt/arm/gst/include/ sb2 ./configure --prefix=/opt/gtkfb --with-gfxdrivers=none --with-inputdrivers=all --enable-png --enable-jpeg --enable-tiff=no --enable-zlib --enable-sdl=no --enable-gif=no --disable-x11
sb2 make install
13) pixman-0.18.2
LDFLAGS=-L/opt/arm/gst/lib CPPFLAGS=-I/opt/arm/gst/include/ sb2 ./configure --prefix=/opt/gtkfb --disable-gtk
14) cairo
LDFLAGS=-L/opt/gtkfb/lib CPPFLAGS=-I/opt/gtkfb/include/ sb2 ./configure --prefix=/opt/gtkfb --without-x --disable-xlib --disable-xlib-xrender --enable-directfb --enable-freetype --disable-win32 --enable-pdf --enable-ps --enable-svg --enable-png
15) Pango
LDFLAGS=-L/opt/gtkfb/lib CPPFLAGS=-I/opt/gtkfb/include/ sb2 ./configure --prefix=/opt/gtkfb --without-x
16 gtk
LDFLAGS=-L/opt/gtkfb/lib CPPFLAGS=-I/opt/gtkfb/include/ sb2 ./configure --prefix=/opt/gtkfb --with-gdktarget=directfb --without-x --without-libtiff --disable-glibtest --disable-cups
Now to compile a simple helloworld.c pro-gramme with these libraries.
export PKG_CONFIG_PATH=/opt/gtkfb/lib/pkgconfig
arm-linux-gcc -Wall -g helloworld.c -o helloworld `pkg-config --cflags gtk+-2.0` `pkg-config --libs gtk+-2.0` -Wl,-O1 -Wl,-rpath,/opt/gtkfb/lib
