Hello,

When using chromium version 122.0.6261.89 and trying to build using the Xcode 16 command line tools, I get the errors as shown in the attached document. From my understanding, it feels like the issue lies with clang/c++ versioning used between Xcode 16 and 122.

I have succeeded in building the latest iOS stable chromium 129.0.6668.46, but I am not aware how I can update the relevant files to allow build to succeed without having to upgrade my entire codebase from 122 to the 129 version.

Any advice and help is greatly appreciated.

Thank you!

Generally, only the most recent version of stable Xcode is supported. (And oftentimes the current Xcode beta as well.) While you could attempt to search through Gerrit to find any changes which were made in order to build cleanly, it would be easier to simply use the version of Xcode which was stable during M122 development.

i have fix this problem. we only need add two headers in "third_party/libc++/src/include/cstddef", and we can build 119.0.6045.214 successfully by xcode 16.2

#include <__stddef_max_align_t.h>
#include <__stddef_offsetof.h>
