   mkdir build

The build currently fails due to removed features from glibc 2.42 (see https://github.com/llvm/llvm-project/issues/137321). I have written a patch for this aur repository to fix this, feel free to include it in your package if you can. Best !

The cmake error with load_llvm_config seems to be fixable by adding the line -DLLVM_CONFIG_PATH=/usr/bin/llvm-config-15 to the cmake_args list in the build step:

build() {
  cd compiler-rt-$pkgver.src/build

  local cmake_args=(
    -G Ninja
    -DLLVM_CONFIG_PATH=/usr/bin/llvm-config-15
    -DCMAKE_BUILD_TYPE=Release
    -DCMAKE_INSTALL_PREFIX=/usr/lib/llvm15
    -DCMAKE_SKIP_RPATH=ON
    -DCOMPILER_RT_INSTALL_PATH=/usr/lib/llvm15/lib/clang/$pkgver
  )
  cmake .. "${cmake_args[@]}"
  ninja
}

I get the same error :( package doesnt work and I need this for postgresql14

I am getting this error:

CMake Error at cmake/Modules/CompilerRTUtils.cmake:300 (message):
  llvm-config failed with status 1
Call Stack (most recent call first):
  CMakeLists.txt:71 (load_llvm_config)
