I am building it from the recommendation for Mesa-19.1.4
The first time I ran the build, it did not give useful
information. The second time it did give more information, but not
useful enough for any searches I tried.
"g++: fatal error: Killed signal terminated program cc1plus"
saying the compiler crashed?
Here is the output from second run.

After some research, I was finally able to find the build log (
CMakeFiles/CMakeError.log)
Run Build Command(s):/usr/bin/ninja cmTC_4c78c && [1/2] Building

Anyone know anything about this unrecognized command?
I'm not familiar with it but doing some searching it appears to be
clang only. Are you exporting CC=gcc CXX=g++? Tests probably
shouldn't be run with those set.

I am doing as shown in the link (
http://www.linuxfromscratch.org/blfs/view/stable-systemd/general/llvm.html
):
=====================================================================
CC=gcc CXX=g++ \
cmake -DCMAKE_INSTALL_PREFIX=/usr \
-DLLVM_ENABLE_FFI=ON \
-DCMAKE_BUILD_TYPE=Release \
-DLLVM_BUILD_LLVM_DYLIB=ON \
-DLLVM_LINK_LLVM_DYLIB=ON \ -DLLVM_ENABLE_RTTI=ON \
-DLLVM_TARGETS_TO_BUILD="host;AMDGPU;BPF" \
-DLLVM_BUILD_TESTS=ON \
-Wno-dev -G Ninja .. &&
ninja
=====================================================================
Should I remove the DLLVM_BUILD_TESTS=ON, or set it to OFF?
You can do that, but it shouldn't be necessary. My instruction is the
same as above. I have no reference to cmTC_ in my log.
-- Bruce
It did not make any difference.
What about compiling Clang directly and changing to:
CC=clang CXX=clang++
