| # GN |
| |
| GN is a meta-build system that generates build files for |
| [Ninja](https://ninja-build.org). |
| |
| ## Getting started |
| |
| git clone https://gn.googlesource.com/gn |
| cd gn |
| python build/gen.py |
| ninja -C out |
| |
| 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`. |
| |
| ## Sending patches |
| |
| GN uses [Gerrit](https://www.gerritcodereview.com/) for code review. The short |
| version of how to patch is: |
| |
| ... edit code ... |
| ninja -C out && out/gn_unittests |
| |
| Then, to upload a change for review: |
| |
| git commit |
| git push origin HEAD:refs/for/master # This uploads for review. |
| |
| When revising a change, use: |
| |
| git commit --amend |
| git push origin HEAD:refs/for/master |
| |
| which will add the new changes to the existing code review, rather than creating |
| a new one. |
| |
| TODO: AUTHORS, CLA, etc. |
