I didn't notice this the first time, but there are a couple changes of the semantics. Now if you say --enable-egl-dri2, configure will fail if you don't have XCB_DRI2. I think that's OK since the user has to explicitly enable the option. However, now the LIBUDEV dependency is unconditional, too. Is libudev required for egl-dri2? -- Dan _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
