If you're not developing something specific to the llvm version currently in development, you probably don't need a git/svn checkout of llvm, you should just use one of the llvm releases. If you encounter build issues using a released llvm, you should report that, as they are all supposed to work (with a minumum, currently at 3.9/4.0 depending on what you include in your build). > > Thanks. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
