Utilizing Bazel for Cross-Platform and Cross-Architecture Compilation an...
summary
A Bazel-based, hermetic C++ toolchain builds static Clang compiler packages and SDK sysroots for Linux, Windows, and macOS and targets Intel and ARM, using only native Bazel features (toolchains, platforms, transitions). It stitches Linux sysroots from a few RPMs, forces compilers to avoid host fallbacks, and produces hermetic C++ toolchain artifacts that run on older CentOS. A simple split transition duplicates dependency trees to emit universal macOS binaries and is used in production to deliver a single large statically linked binary.
