i spent a few hours playing with it just now. looks nice but its dealing with makefiles is extremely crappy. unless someone can be bothered to configure the full IDE settings as they are set up in the makefile, I don't see codelite happening. It overwrote my ctrulib makefiles without telling me and refuses to compile code with the reverted makefile, despite it building just fine from the commandline..I found this one:
http://codelite.org
Looks very nice! I'll look into it. It is already cross-platform and it already supports c/c++
