I'm seeing this assertion failure on an Intel Mac as well, macOS 14 Sonoma.

This is a bug of new ld shipped with Xcode 15. A simple workaround is to use previous ld. I changed the --with-ld=${prefix}/bin/ld in lang/gcc12/Portfile to --with-ld= /Library/Developer/CommandLineTools/usr/bin/ld-classic then I can build libgcc12 and gcc12 without problem.

Please can someone on macOS14 test the above commit and report back here.

Replying to freedomtan:This workaround is working for me as well.

Building was successful.

Thanks!

I still see this issue. My system is:

macOS 13.6 22G120 arm64 Xcode 15.0 15A240d

[cjones051073 (Chris Jones)]

Please ensure your ports are up to date and then try again. I have exactly the same system and the current version built fine for me.

[szhorvat (Szabolcs Horvát)]

Sorry, I should have been more specific. Trying to build just about anything with GCC, including GCC13, triggers this linker crash. It was not clear to me whether this was fixed only in the context of building libgcc12, or more generally when using GCC. I am referring not to building ports, but using GCC in general to build any project.

My ports are up to date.

[cjones051073 (Chris Jones)]

The fixes in the GCC port only fix building the port. When you use it yourself you will also need to revert to the using the classic linker as required. Basically, make sure you use -Wl,-ld_classic

It is reported that the Xcode 15.1 beta fixes this issue, so should disappear soon enough
