@pbchekin could you please provide steps to reproduce the error? Please assign it back to me after.

[pbchekin]

You can reproduce it with cibuildwheel tool (requires docker).

pip install cibuildwheel

echo "" >> python/setup.cfg
echo "[build_ext]" >> python/setup.cfg
echo "base-dir=/project" >> python/setup.cfg

export CIBW_ENVIRONMENT="TRITON_BUILD_WITH_CLANG_LLD=1"
export CIBW_BEFORE_ALL="dnf install clang lld -y"
export CIBW_BUILD="cp3{9,10,11,12}*-manylinux_x86_64"
export CIBW_MANYLINUX_X86_64_IMAGE="quay.io/pypa/manylinux_2_28_x86_64:latest"
export CIBW_SKIP="cp{35,36,37}-*"
export CIBW_BUILD_VERBOSITY=1
python3 -m cibuildwheel python --output-dir wheelhouse

@ZzEeKkAa another way to reproduce in our JupyterHub session:

curl -sSLO https://apt.llvm.org/llvm.sh
sudo bash ./llvm.sh 17
