It appears OSX-15 doesn't have 80bit reals.

[rikkimax]

Ugh oh.

ld: multiple errors: symbol count from symbol table and dynamic symbol table differ in '/Users/runner/work/dmd/dmd/generated/build.o' in '/Users/runner/work/dmd/dmd/generated/build.o'; address=0x0 points to section(2) with no content in '/Users/runner/dlang/dmd-2.099.1/osx/lib/libphobos2.a2942'

Bootstrap compiler not supporting macos-14: #21986

[rikkimax]

x87 not supported by macos-15: #21987

[rikkimax]

Code coverage for OSX is still dead, disabling again.

[rikkimax]

I'll bump the timeout to 1 hour. I hate doing it, but we must see OSX runner pass.

Also: macOS 13 x64, DMD (bootstrap) needs to be removed from the repository settings as required to be completed.

Ohh I see, I think its this that is causing the issue:

ld: warning: ignoring duplicate libraries: '-lm', '-lpthread'

[rikkimax]

Gonna try the fix that everyone else is using for this (change in linker for XCode 15): https://indiestack.com/2023/10/xcode-15-duplicate-library-linker-warnings/

[rikkimax]

That did not work.

I can't fix that, nor run it locally.

[rikkimax]

Hmm, I bet if I forced the solution I said above about duplicate libraries for OSX would be good enough here.

It must be outputting it to stderr:

ld: warning: ignoring duplicate libraries: '-lm', '-lpthread'
rm generated/osx/debug/64/invalid_memory_operation generated/osx/debug/64/stderr_msg

[rikkimax]

If I've applied it correctly, it does mean XCode < 15 won't work with dmd anymore.

[rikkimax]

Hmm I wonder if CC is linking against those two libraries by default, and we shouldn't be specifying them on OSX at all.

[rikkimax]

If bumping to 16.2 fixes make not having the private modifier, then I need to verify if we still need -Wl,-no_warn_duplicate_libraries if we don't need this linker flag then this won't need a changelog.

[rikkimax]

After many days I have learned that something is forcing the XCode's make over homebrew's gmake.

Put the right path into a var at the right place, and ignore the symlink and it seems to be working.

[rikkimax]

I now have permissions, and I have removed osx13 as a requirement. Will revisit this when not as tired as I am now as to if it should merge.

[rikkimax]

Ok, I'm happy.
