Don't know if this is expected or not, but llvm built like -
cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Release
now fails to build mesa (I also tried without vulkan and it still fails
/usr/lib/libLLVMSupport.a(Process.cpp.o): In function
undefined reference to `setupterm'
undefined reference to `tigetnum'
undefined reference to `set_curterm'
undefined reference to `del_curterm'
collect2: error: ld returned 1 exit status
Haven't tried llvm with -DLLVM_APPEND_VC_REV=ON yet, mesa still builds
OK with this commit reverted.
My mesa config =
./autogen.sh --prefix=/usr --sysconfdir=/etc --enable-texture-float
--enable-opencl --enable-omx --with-egl-platforms=x11,drm,wayland
--enable-gbm --enable-shared-glapi --enable-glx-tls --with-dri-drivers=
