Build failure on macOS (M2 Max)

[Yan Pujante]

Hello

I am trying to build on macOS (Ventura 13.4 / M2 Max). I followed the instructions on the DevSetup page. 

I created/checkout a branch to the latest stable version (d987078) (per Chromium Dash https://chromiumdash.appspot.com/releases?platform=Mac)

When I run the build command it fails with this error message:

[1/141] CXX obj/translator/SymbolEnv.o

I am not too sure what to do about it... Any idea what is going on?

Thank you

Can you give the main branch a try?

Ok. I just did and it does work. It is just very weird that it would not work on a commit that was marked stable for a release...

Thanks

[Geoff Lang]

I'm sure if you build it within a chromium checkout, it will work. Looks like there may be an incorrect dependency on some compiler version for that branch.
