I have updated plan9port to build and run on OS X Lion. Everything works except devdraw, the binary that handles putting windows on the screen and managing the mouse and keyboard.
Devdraw was written 3 years ago, using the Carbon framework. Apple wants to retire that framework, so they have been slowly chipping away at its functionality. It is time to convert $PLAN9/src/cmd/devdraw/osx-screen-carbon.m to Cocoa. There is a previous attempt in osx-screen.m, but I would not start with that, because it has not kept up with recent changes (like Multitouch) and bug fixes. The Carbon source is a better starting point. Is there anyone out there who knows Cocoa and Objective C well enough that this would be very easy? I am sure I could figure it out given enough time, but enough here is likely quite large. It would also be nice to convert $PLAN9/src/cmd/fontsrv/osx.c, but that is much lower priority, as it appears to build okay still. Thanks. Russ
