Hi,
it's probably time to celebrate! For the first time in nearly two years I've been able to get a version of Gem running without any crashes on window close *and* with an actual rendering on a Mesa/DRI-enabled fully open source Intel Linux system. Die Zeit heilt alle Wunden.
This is with a bleeding edge Debian unstable system with UXA, GEM (the other) and KMS enabled (2.6.30 kernel), and similarily bleeding edge hardware: my new powersaving battery lifetime wonder (almost 8h!) travel system Acer Timeline 3810T SU3500 CULV single core with some Mobile Intel® GS45 Express Chipse inside.
The Gem running is the svn snapshot from today, Pd is 0.42 from Miller's site with tcl/tk 8.5. Interestingly the Debian supplied Pd/Gem in unstable crashes as soon as I even open any Gem patch in GLclearColor or so (don't remember).
I don't need to use any GL_SINGLE_CONTEXT environment stuff, just fire up pd -lib Gem and all is well.
I should have come to Brazil and treat you to some beer thing, but you'll get one at a later occasion!
Thanks a lot for whatever you did. :)
Ciao
