Compiles libclang.so from the LLVM 18.1.1 source release inside manylinux_2_39_riscv64 and packages it via upstream's own setup_ext.py, mirroring libclang-linux-amd64.yml/libclang-linux-aarch64.yml narrowed to riscv64. Upstream publishes no riscv64 wheel.
setup_ext.py imports distutils directly; Python 3.12 dropped it from the stdlib and pip install wheel alone doesn't pull in setuptools' compatibility shim, so the wheel build died with ModuleNotFoundError after the full LLVM/Clang compile finished (gotcha 211).
wheel>=0.44.0 dropped wheel.bdist_wheel.get_platform in favour of setuptools' own bundled bdist_wheel command. Upstream's setup_ext.py imports get_platform directly from wheel.bdist_wheel, so an unpinned `pip install -U wheel` now breaks it with: ImportError: cannot import name 'get_platform' from 'wheel.bdist_wheel' right after last commit's distutils fix gets past the first import. Reproduced and fixed against the real setup_ext.py + a stub native/ tree in quay.io/pypa/manylinux_2_39_riscv64 (no LLVM rebuild needed): wheel 0.48.0 fails identically, wheel==0.43.0 produces a real wheel. Filed as gotcha 225.
