All, Note: v5 is ready now. This fixes the problem I was having with setitimer interfering with the Objective-C stuff. I re-implemented Itimer.c using a pthread. http://hip-to-be-square.com/~blackh/ghc-iphone-new/v5/ My next task will be to get this onto github. After that I'll get a real Haskell-based OpenGL skeleton app going. (Thanks Carl Joachim Svenn for your assistance.) Steve
