Porting GTK, requirements

["listreader joost cx" <listreader joost cx>]

Hello all,

I was wondering if anybody could list the requirements for a full GTK port
to another operating system. Does a complete posix system need to be in
place ? Does it require a certain directory structure ? Is there a list of
successful GTK ports to non-unix systems ? Are there any such initiatives
in progress ? What about framebuffer/input requirements ?

Thanks a lot!
Joost
