  • Is LLVM strictly required for building Mesa(Gallium/Radeon)?

    I am trying to build Mesa master 10.0-git and it seems regardless if I set --disable-galllium-llvm and --disable-r600-llvm-compiler configure-time option, the configure still searches and requires LLVM >3.3. Is it a hard dependency? Is it required, if I just want to use shader optimizer and no LLVM whenever possible? Thanks!

    Is there an OpenCL build switch? LLVM is required for OpenCL. Other option, try disabling RadeonSI build support-- I'm not positive but LLVM may be required for RadeonSI

      if you just want r600g this should work:

      Code:
      --with-dri-drivers= --with-gallium-drivers=r600 --disable-gallium-llvm
      for radeonsi you need llvm.
