Installation & Usage

Extract Archives

All archives are compressed with zstd. You'll need zstd to extract them:


                    tar --use-compress-program=unzstd -xvf llvm-21.1.5-win-x86_64.tar.zst

Verify Checksums

For files with checksums, verify integrity before use:


                    sha256sum -c llvm-21.1.5-win-x86_64.tar.zst.sha256

Integration

These binaries are designed to work seamlessly with the clang-tool-chain project, which provides automated installation and management.
