# How to update the [GN binaries](gn.md) that Chromium uses. |
-## Prerequisites |
- |
-You'll need a checkout of Chromium, and commit access to the |
-`buildtools/` repo. Check with scottmg, thakis, brettw, dpranke, or a |
-member of chrome-infra to get access to that repo. |
- |
-## Instructions |
- |
-_Hopefully there will be a script that does this all for you shortly._ |
- |
- 1. cd to your Chromium checkout. |
- 2. Create a whitespace change in DEPS and upload it to create a "dummy" CL |
- 3. Run the following commands: |
- 1. git-cl try -b linux\_chromium\_gn\_upload\_x86 |
- -b linux\_chromium\_gn\_upload\_x64 |
- -r $GIT\_REVISION\_YOU\_WANT\_TO\_BUILD |
- 2. git-cl try -b mac\_chromium\_gn\_upload |
- -r $GIT\_REVISION\_YOU\_WANT\_TO\_BUILD |
- 3. git-cl try -b win8\_chromium\_gn\_upload |
- -r $GIT\_REVISION\_YOU\_WANT\_TO\_BUILD |
- 4. Wait for the try jobs to finish. |
- 5. If they all ran successfully, copy the digests from the tryjob build |
- log output into `src/buildtools/{mac,linux32,linux64}gn.sha1` and |
- `src/buildtools/win/gn.exe.sha1` as appropriate. |
- 6. Upload a buildtools CL with the updated digests and get it reviewed |
- and committed. Make sure you note the revision of GN that you built |
- against in the commit message. |
- 7. Go back to your "dummy" CL w/ the change to the DEPS file in src/ |
- and update the buildtools revision to your newly-committed |
- buildtools change. |
- 8. Get that reviewed and landed in Chromium. Make sure you note the |
- revision of GN that you built against in the commit message, along |
- with the revision of buildtools that you're rolling to. |
+Any committer should be able to do a roll by running //tools/gn/bin/roll_gn.py |
+on linux or mac. |
