But basically i'd say yes. There are some projects for user interfaces on mobile devices using GTK. (e.g. GPE - http://gpe.handhelds.org and Maemo - http://maemo.org). > 2. What is based on? Or what lib does it require? The whole UI framework is split into several libraries, you need pango, atk, glib, X (use kdrive!) and libraries for graphic types you need to support (e.g. libjpeg). Depending on what you intend to do it might be a good idea to check out OpenEmbedded (http://www.openembedded.org) which is very powerful if you want to create complete filesystem images (or crosstoolchains) for embedded and mobile devices. It includes pretty good support for GTK and has definitions for various devices. > 3. Can it be compared to Qt/E or MiniGUI? What are the advantages and > disadvantages? GTK might be a little bit bigger than these two, but it is very powerful and there are bindings for many languages available. I personally like GTK because its native language is C instead of C++ and its good support for powerful themes. It is easy to develop applications on a desktop PC using the same API like on your embedded device and if necessary you can port applications to run on that one easily. In addition to this GTK is LGPL licensed which is much easier to deal with compared to the dual licensing crap for Qt/E. > 4.

It is a very good idea to have an API reference, witout htis you are lost in a compley toolkit like GTK. Devhelp e.g. is very useful. > 5. What hardware does it support? Does it support omap5912? It should be able to run on almost everything you can compile it for. OpenEmbedded already has support for this CPU, so i guess you can build GTK for it easily. I use it on an omap1710, Strongarm and Xscale CPUs frequently. > 6. What is the steps of building gtk+ for embedded system? Basically you just need a crosstoolchain for your platform and compile all the libraries in the correct order. Thats a little bit tricky because you need to find out whch one depends on what. You would compile and install them with the prefix of your toolchain first and then with the correct prefix and settings for your target filesystem again. If there is a particular reason not to let a tool (like OpenEmbedded or T2) do this for you could try Scratchbox (scratchbox.org) which creates a sandbox environment for cross development.
