GN
GN is a meta-build system that generates build files for Ninja. There is documentation in docs/.
Getting started
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
.
Reporting bugs
If you find a bug, you can see if it is known or report it in the bug database.
Sending patches
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.
We ask that all contributors sign Google's Contributor License Agreement (either individual or corporate as appropriate, select 'any other Google project').
