Hermetic Clang Toolchain for Bazel

A fully hermetic Clang/LLVM toolchain for Bazel that produces completely
self-contained, statically linked binaries with zero host system dependencies.

Hermeticity

  • hermetic: Produces statically linked binaries with no host dependencies
  • clang 18.1.8: Uses pre-built LLVM/Clang compiler
  • musl libc: c/c++ standard libraries fetched from Alpine repo
  • libstdc++ 14.2.0: Alpine's C++ standard library built for musl
  • statically linked: All binaries are statically linked (no dynamic dependencies)

Usage

Add this to your MODULE.bazel:

bazel_dep(name = "hermetic_clang_toolchain", version = "1.0.0")

hermetic_clang = use_extension("@hermetic_clang_toolchain//clang_toolchain:hermetic_clang.bzl", "hermetic_clang_extension")
use_repo(hermetic_clang, "hermetic_clang_18_1_8")

register_toolchains("@hermetic_clang_toolchain//clang_toolchain:hermetic_clang_toolchain")

Add this to your .bazelrc:

# Disable default C++ toolchain detection
build --incompatible_enable_cc_toolchain_resolution
build --action_env=BAZEL_DO_NOT_DETECT_CPP_TOOLCHAIN=1

# Use hermetic clang toolchain
build --extra_toolchains=@hermetic_clang_toolchain//clang_toolchain:hermetic_clang_toolchain
