Bug 1356991 (build Stylo in nightly, but keep Stylo pref'd off) will be landing soonish, and building Stylo requires Clang (as a separate tool from the primary compiler) on all platforms. On Tier 1 platforms, `mach bootstrap` will be downloading Clang from our infrastructure, instead of installing Clang from a package manager or similar. This method ensures that we're using the same version of Clang that's being used to build Stylo on our build machines and also serves as a testbed for downloading more things (e.g. actual build toolchains and supporting tools) from our infrastructure.[0]
Although we can do local testing, there are a wide variety of build configurations out there. Getting all these tested ahead of actually building Stylo and fixing any issues would help make the transition smoother. If you're so inclined, it would be helpful if you would: 1. Run `mach bootstrap` on an updated mozilla-central checkout and answer "yes" to whether Stylo-related packages should be downloaded. 2. (If applicable) Report any problems to Core :: Build Config. 3. Follow the instructions printed out about applying changes to your mozconfig. You may want to use a separate mozconfig than what you normally use. 4. Build with the mozconfig you set up in step 3. (Bug 1368177 may make this difficult on Windows; feel free to apply the patch there locally or add backslash escapes for spaces in paths manually.) 5. (If applicable) Report any problems to Core :: Build Config. Please CC me on all bugs filed. Thanks! -Nathan [0] Using Clang from a package manager should work, but it's not what we're supporting. Tier 3 platforms (e.g. *BSD) will have to use Clang via a package manager. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
