Trying to build webview for android in the docker container from ubuntu 18.04.
Do everything according to instruction and last version is built okay with command:
autoninja -C out/Default system_webview_apk
But I need an older version. So I do:
git checkout 80.0.3987.99 -b 80-version
After that run sync:
gclient sync
And it also by default runs hooks after sync. Then again I start build with the same cmd:
autoninja -C out/Default system_webview_apk
But this time on checkout build it gives me error, which I can't fix for hours:
user@0bb1627b6f62:~/workdir/chromium/src$ autoninja -c out/Default/ system_webview_apk
depot_tools/ninja.py: Could not find Ninja in the third_party of the current project, nor in your PATH.
Please take a following action to install Ninja.
- If your project has DEPS, Add a CIPD Ninja dependency to DEPS.
- Otherwise, add Ninja to your PATH *after* depot_tools.
But when I switch again to the main branch, do sync, it is built fine!
What I do wrong? gn args runs okay in both cases.
On the main branch there is src/third_party/ninja/. On the checkout branch after gclient sync this folder disappears. Before sync autoninja run gives error unknown function because ninja's version doesn't correspond to the checkout version.
Well, it turned out that for some reason sync doesn't fetch ninja for my checkout even with gclient sync --with_branch_heads command. And I was confused by
Ninja is included in depot_tools so there's nothing to install.
from chromium docs. Moreover I thought that ninja version should correspond to my chromium checkout, but as far as I found out it concerns with gn tool only.
So, my solution was just to add to my docker file
apt install ninja-build
and every checkout started to build with no problem.
