What exactly happened there? LLVM upstream generates shared libraries named libLLVM-<major>.<minor>.so*, so it shouldn't be possible for a simple LLVM package update to break Mesa, unless Arch did something really stupid. >> Tl;Dr; We really want to enable static linking by default and prod >> distros to use it. > > I'm all in favor of statically linking LLVM (that's the way I'm doing this on > my pc). > I think the only reason this is not done is because people (also here on the > list) don't want any static linkg of external libraries because of size or > whatever. > So changing the default to static is easy, but I doubt it will make everyone > happy ;-) Indeed, it'd probably make many distro packagers unhappy, because they'll just have to re-enable shared linking, because packaging policies generally strongly discourage if not outright forbid static linking. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
