Add gn check --check-generated to check dependencies of generated files A fair amount of source in Chromium involves generated files now, through mojo or through the jumbo build system. The current gn check will not, and can not, check includes in those files since they can't exist until a build has run. This adds a gn check flag: --check-generated, which allows gn check to also look through generated files. For obvious reasons it can only be used once those generated files have been created. Bug: gn:57 Change-Id: I3f65b8ca4131931af8906d614334ebce9b006f5d Reviewed-on: https://gn-review.googlesource.com/c/gn/+/4181 Reviewed-by: Brett Wilson <brettw@chromium.org> Commit-Queue: Brett Wilson <brettw@chromium.org>
GN is a meta-build system that generates build files for Ninja. There is documentation in docs/ and a presentation on it.
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.
