building julia fails for x86_64 on macOS 15 (Xcode 16): error: non-private labels cannot appear between .cfi_startproc / .cfi_endproc pairs

[nklb (Niklas)]

I get the following error trying to build julia on an Intel MacBook after migrating to macOS 15 :

The current Xcode can't build certain older versions of llvm/clang unless they are patched. There are a number of current PRs applying the needed patch to older MacPorts versions of llvm.

It looks like Julia contains a bundled llvm -- presumably it needs a similar fix.

Better fix would be to update Julia to use a newer version of LLVM that works 'out the box' on macOS15+, e.g. LLVM-18+

[cjones051073 (Chris Jones)]

Actually, its not obvious LLVM is the issue here. The attached log file is corrupt so I cannot read it but it could be GCC the problem here, but in that case the fixes are already committed (or should be).

I do wonder if the OP does not have their ports up to date, so the first thing would be to

> sudo port sync
> sudo port upgrade outdated

then try again, and if it still fails please upload a non-corrupted clean log file.

[nklb (Niklas)]

I just tried this but got the same error. Also the generated log (new attachment) seems similar.

Before I ran into the issue #70866 installing gcc, which could be fixed using the proposed patches.

gcc is already fixed. If you are not picking those fixes up your ports are out of date.

[nklb (Niklas)]

They are up to date now and have been when I reported this problem. (My problems with gcc came up while it was being fixed/ before the patch was included - probably not relevant)

[cjones051073 (Chris Jones)]

OK, then this is one for the maintainers to look into

which of course they already did in master, last month

So another option is just to wait for a new release with this commit in it.

Depends on how badly people want Julia right now.

The llvm patch is just so darn trivial seemed like someone might be motivated to try it :)

I was going to take a stab at fixing this, however on my daily-use arm64 machine, Julia installs without any trouble:

% port -v installed julia 
The following ports are currently installed:
  julia @1.10.5_0+gcc14 (active) requested_variants='' platform='darwin 24' archs='arm64' date='2024-09-27T12:33:15-0700'

[markemer (Mark Anderson)]

Yeah, me too. Julia built fine for me on arm64. This very well could be a leftover from our bad clangs and llvms. Does it build on the build bot?

[cjones051073 (Chris Jones)]

I've scheduled a build on the build bots for macOS15 but it will be a while before they get around to it. we don't even have the arm builedbot running yet.

Yeah, I was gonna ask - I'm still trying to pick up how the infra works. (Only been using the project for 20 years - seems about time)

[cjones051073 (Chris Jones)]

builedbot build failed for intel. See

[benz0li (Olivier Benz)]

There is Julia 1.11.0 now: ​https://github.com/macports/macports-ports/pull/26121

[cjones051073 (Chris Jones)]

Still fails on macOS15 Intel
