[cfe-users] Issue with clang-13

[Sunil Kumar via cfe-users]

Hi,
I tried many times to install clang-13 in ubuntu-16.04. I followed the
steps mentioned below.

   - git clone https://github.com/llvm/llvm-project.git
   - git checkout llvmorg-13.0.0
   - cd llvm-project
   - mkdir build
   - cd build
   - cmake -DLLVM_ENABLE_PROJECTS=clang -G "Unix Makefiles" ../llvm
   - make

After running make command, it failed to install clang eventually and
showed some error mentioned below

make:342: recipe for target 'bin/clang-13' failed
make[2]: *** [bin/clang-13] Error 1
make[2]: *** Deleting file 'bin/clang-13' CMakeFiles/Makefile2:38992:
recipe for target 'tools/clang/tools/driver/CMakeFiles/clang.dir/all'
failed
make[1]: *** [tools/clang/tools/driver/CMakeFiles/clang.dir/all] Error 2
collect2: fatal error: ld terminated with signal 9 [Killed] compilation
terminated.
-
Please help to resolve this bug.

Thanks Matthew. I am using the x86_64 system.
I wanted to ask you one more question. After installing clang, how to
install openmp with the *OMPT tool *interface in clang-13.
