Each library was built with Visual Studio 2012 in 32 and 64 bits without the Windows XP support. This build passes many test on Windows Vista, 7 and 8 with many applications and official samples built with MSVC 2012 on Windows 7, with MSVC 2010 and with MSVC 2008 on Vista and MSVC 2012 on Windows 8. The installer allows the user to choose the most appropriate installation for him (only Gtk+, only DLL, only 32 bits, full installation 32/64 bits with Libs and headers, etc...) Enjoy !

ChumbOS Launcher is a native C application that is designed to break the shackles of the Chumby, so that not only flash applications can take advantage of the cute little colour screen, touchscreen input, rotary encoder and it's majestic Chumby Button. By the way, not that it had too many shackles, don't get me wrong, but the limitation of using only flash widgets on a device having the horse power of a 450MHz full blown computer, seems to me, a bit of a waste and just a bit annoying. So, what does this application do? It enables you to design a simple Graphical User Interface (GUI) which can start and stop other applications on the Chumby.
