Windows build failure: The filename or extension is too long

[jtbandes]

I'm experiencing a build failure on Windows due to long path names. Any advice for fixing or working around this would be appreciated. Thank you! 🙏

Operating System

GitHub Actions runner - Microsoft Windows Server 2022 / 10.0.20348
windows-2022 image https://github.com/actions/runner-images/blob/win22/20241021.1/images/windows/Windows2022-Readme.md

To Reproduce

• git config --global core.filemode false
• git config --global core.autocrlf false
• git config --global branch.autosetuprebase always
• git config --global core.longpaths true
  • This was necessary to make e init and e sync work
• npm i -g @electron/[email protected]
• e init mybuilder --import release --reclient none --target-cpu x64
• e sync --revision v33.0.2
• e build

Expected Behavior

Build passes

Actual Behavior

Build failure:

May be related to ninja-build/ninja#2359 / ninja-build/ninja#1900 ?

However, it appears that DEPS already specifies ninja 1.12.1.

[jtbandes]

I've tried a couple things to work around this:

• Use cmd.exe (found this suggestion somewhere although I forgot where)
• Run New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem" -Name "LongPathsEnabled" -Value 1 -PropertyType DWORD -Force before the build (sounds like it helped in Should support filename longer than 260 characters ninja-build/ninja#1900)

However things are still not working. I wonder if the version of ninja being used is not the one I thought I found in DEPS?

You can try the old version 1.8.2.

[jtbandes]

How would I do that? Modify DEPS?
