Error running "ninja check" after building latest LLVM and Clang on Linux Ubuntu 22.04 #114498

Open bobhairgrove opened 4 hours ago

bobhairgrove commented 4 hours ago

Platform is Linux Ubuntu 22.04 with g++ version 11.4.0.

I tried to clone and build LLVM and Clang from source following the instructions found here: https://clang.llvm.org/docs/LibASTMatchersTutorial.html

My clang-llvm directory is not directly under the $HOME directory, but in /home/bob/code/clang-llvm, so I cloned the source code from GitHub as follows:

cd ~/code
mkdir clang-llvm
cd clang-llvm
git clone https://github.com/llvm/llvm-project.git

Output:

CMake and ninja were already installed in my system; their versions are:

cmake --version
cmake version 3.26.3

ninja --version
1.10.1

Then I did:

cd clang-llvm/
mkdir build && cd build
cmake -G Ninja ../llvm-project/llvm -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra" -DCMAKE_BUILD_TYPE=Release -DLLVM_BUILD_TESTS=ON

Then I ran:

ninja

There were quite a few warnings, but it seemed to run successfully. Finally, I ran:

ninja check

The last command failed. Here is the complete output with the error message at the end:

I'm not a stranger to configuring and compiling things from source, but I do feel somewhat overwhelmed by the messages here. Can anyone please tell me exactly what failed, and how I might rectify this?
