Is anyone else seeing similar errors? or am i missing something? Thanks Anuj _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org <mailto:mesa-dev@lists.freedesktop.org> http://lists.freedesktop.org/mailman/listinfo/mesa-dev That's a surprising failure, since that assertion would only be expected to be hit if brwInitFragProgFuncs() got called more than once on the same context. That in turn should only happen if the driver's CreateContext() function got called more than once on the same context, and it's hard to see how dri2CreateContextAttribs() would ever do that. Note: I've heard that there have been some build problems recently; have you tried building from scratch just to be sure? I happen to be reinstalling my OS today, so I've just done a clean build, install, and piglit run on mesa commit dc435ae, and everything looks fine. If a clean build doesn't help for you, I'd recommend either bisecting to try to see if a recent commit introduced the problem, or else using gdb to see if brwInitFragProgFuncs() is getting called multiple times, and if so, why. clean build didn't help. It shows assertion failure while executing brwInitFragProgFuncs() for the first time. A fresh clone of mesa git repository works fine. Thanks Anuj
I think you might have to throw out your lib/ directory. There's a bug where it can pick up an old libdricore.so, or the one from your system, which is pretty nasty. I think Eric was looking into a fix...
