Use getenv to get TMPDIR path on macOS as well This avoids the dependency on bundles or frameworks and it's the solution used by other tools such as Ninja and even C++ standard library. Change-Id: I423a8919ee67b6734e090a783122fb094481724e Reviewed-on: https://gn-review.googlesource.com/c/2941 Reviewed-by: Scott Graham <scottmg@chromium.org> Commit-Queue: Petr Hosek <phosek@google.com>
GN is a meta-build system that generates build files for Ninja. There is documentation in docs/.
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.
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.
