win: Slightly simplify build flags. /O2 is the same as /Ox /Gy /GF (and /GF is on by default), so use /O2 instead of /Ox /Gy. No behavior change. Bug: none Change-Id: Ic77716535d492931e0f5d0422cba36c2ea8e2cdb Reviewed-on: https://gn-review.googlesource.com/c/3320 Reviewed-by: Scott Graham <scottmg@chromium.org> Commit-Queue: Scott Graham <scottmg@chromium.org>
GN is a meta-build system that generates build files for Ninja. There is documentation in docs/.
You can download the latest version of GN binary for Linux, macOS and Windows.
Alternatively, you can build GN from source:
git clone https://gn.googlesource.com/gn cd gn python build/gen.py ninja -C out # To run tests: out/gn_unittests
On Windows, it is expected that cl.exe, link.exe, and lib.exe can be found in PATH, so you'll want to run from a Visual Studio command prompt, or similar.
On Linux and Mac, the default compiler is clang++, a recent version is expected to be found in PATH. This can be overridden by setting CC, CXX, and AR.
If you find a bug, you can see if it is known or report it in the bug database.
GN uses Gerrit for code review. The short version of how to patch is:
Register at https://gn-review.googlesource.com. ... edit code ... ninja -C out && out/gn_unittests
Then, to upload a change for review:
git commit git cl upload --gerrit
When revising a change, use:
git commit --amend git cl upload --gerrit
which will add the new changes to the existing code review, rather than creating a new one.
