Description Chris Rankin 2017-08-16 10:38:22 UTC

Building on Fedora 26, and configuring Mesa as:

CFLAGS='-O2 -g -gdwarf-2' ./autogen.sh --prefix=/home/chris/Programs/local-mesa --libdir=/home/chris/Programs/local-mesa/lib64 --with-vdpau-libdir=/home/chris/Programs/local-mesa/lib64/vdpau --with-gallium-drivers=radeonsi,swrast --with-egl-platforms=drm,x11 --with-llvm-prefix=/home/chris/Programs/local-llvm --enable-llvm-shared-libs --with-dri-drivers= --enable-texture-float --enable-64-bit --enable-nine --enable-omx

However, the build fails with:

  CXXLD    gallium_dri.la
/home/chris/Programs/local-llvm/lib/libLLVMSupport.a(Process.cpp.o): In function `llvm::sys::Process::FileDescriptorHasColors(int)':

I've tried updating my local LLVM installation twice, to no avail.

The missing symbols seem to be from libncurses.

https://patchwork.freedesktop.org/patch/171990/ should fix this.

Comment 2 Chris Rankin 2017-08-16 20:45:01 UTC

No, I now get:

configure: error: Could not find llvm shared libraries:
                       Please make sure you have built llvm with the --enable-shared option
                       and that your llvm libraries are installed in /home/chris/Programs/local-llvm/lib
                       If you have installed your llvm libraries to a different directory you
                       can use the --with-llvm-prefix= configure flag to specify this directory.
                       NOTE: Mesa is attempting to use llvm shared libraries by default.
                       If you do not want to build with llvm shared libraries and instead want to
                       use llvm static libraries then add --disable-llvm-shared-libs to your configure
                       invocation and rebuild.

For some reason, I think Mesa is expecting my LLVM installation to contain libLLVMTarget.so rather than libLLVM.so.

Comment 3 Michel Dänzer 2017-08-17 01:17:09 UTC

That's a different, pre-existing issue. To avoid it, build LLVM with either -DLLVM_LINK_LLVM_DYLIB=ON or -DLLVM_APPEND_VC_REV=OFF.

Comment 4 Michel Dänzer 2017-08-17 01:19:56 UTC

BTW, -DLLVM_LINK_LLVM_DYLIB=ON should avoid this bug as well.

Comment 5 Michel Dänzer 2017-08-17 06:21:30 UTC

Thanks for the report, fixed in Git:
