rules_watchman

Hermetic Bazel build for Watchman v2026.07.06.00 using hermetic-llvm.

Supported targets:

• Linux x64 (x86_64-linux-gnu)
• Linux arm64 (aarch64-linux-gnu)
• Darwin arm64 (aarch64-apple-darwin)
• Windows x64 (x86_64-windows-gnu)

Linux binaries statically link libc++ and third-party dependencies; glibc remains dynamic. Darwin uses the Apple system runtime and frameworks. Windows uses Clang, MinGW-w64, UCRT, and libc++; it does not use the MSVC ABI. The optional should_deelevate_on_startup hook is disabled in the Windows Bazel build.

Build any supported target from a registered host:

bazel build //:watchman-x86_64-linux-gnu
bazel build //:watchman-aarch64-linux-gnu
bazel build //:watchman-aarch64-apple-darwin
bazel build //:watchman-x86_64-windows-gnu

Build every distribution binary from one host:

bazel build //:dist

Run the filesystem smoke test with a binary on its matching host:

tests/watchman_smoke_test.sh /path/to/watchman

tests/watchman_smoke_test.ps1 -Watchman C:\path\to\watchman.exe

Development

Install the development hooks once after cloning:

npm ci
