libgcc14 (libgcc14-14.2.0_1+stdlib_flag.darwin_24.arm64.tbz2) failed to build with config error ("configure: error: cannot compute suffix of object files: cannot compile") on macOS Sequoia beta 15.0 Beta (24A5327a)

[avisformosa]

Dear MacPorts community! As described above I negligently updated to the beta of Sequoia (15.0 Beta (24A5327a)). As far as I can tell, the Xcode beta and the Command Line Tools are up to date with the beta, and most things compile without problems, but unfortunately, libgcc fails with the following error:

Any suggestions or is this a generic bug as the "configure: error: cannot compute suffix of object files: cannot compile"-Error is somewhat general - but I did not find any useful work around. Thanks!

[oversized-monday (MONDAY!)]

I poked at this a little bit and when trying to recreate the configure failure, I get an error about -lemutls_w not being found. I'm not familiar with gcc, but this seems to be a library for emulating thread local storage on systems that don't have it. The macports Portfile specifies --disable-tls which suggests that it should be disabled. I don't know if this is a problem with my tests or a hint at the actual problem.

Hopefully this helps point someone more knowledgeable in the right direction.

[kencu (Ken)]

I don't think the config.log you posted is the one with the error in it.

Noted there is a bug with the latest Xcode that prevents building gcc:

​https://github.com/iains/gcc-darwin-arm64/issues/136

[oversized-monday (MONDAY!)]

I manually removed "-pipe" from the gcc14 and libgcc14 Makefiles (after a failed build attempt) and they both built fine. I was able to then build Emacs with native compilation (which uses libgccjit)

I didn't see where gcc14 decides whether to use -pipe when building the Makefiles. If that can be temporarily triggered, we can fix builds while we wait for either Apple to fix their side or for it to be patched upstream by gcc.

[ryandesign (Ryan Carsten Schmidt)]

MacPorts base adds -pipe for all ports if configurepipe is yes in macports.conf, which it is by default.

[oversized-monday (MONDAY!)]

Confirming that setting configurepipe to "no" does work. I did a fresh install and gcc14/libgcc14 built with no issues.

[markemer (Mark Anderson)]

I'll give this a shot later - but I've had issues building gcc/libgcc since the bump to macOS 15.

[amake (Aaron Madlon-Kay)]

I find that setting configurepipe no leads to a different error for me on the final release of Sequoia:

GCC invariably has issues on major OS updates and/or new Xcode versions...

We run in MacPorts Darwin versions from here

​https://github.com/iains/gcc-14-branch

specifically we are running the latest tag, ​https://github.com/iains/gcc-14-branch/releases/tag/gcc-14.2-darwin-r1

The owner of that repo is effectively the Darwin lead in GCC, and very responsive, so please can I request someone running macOS15 (not the beta, the newly available release) and has issues with gcc14 please open an issue against the above repo

​https://github.com/iains/gcc-14-branch/issues

including whatever info you can. At minimum a clean build log for instance.

[markmentovai (Mark Mentovai)]

​https://github.com/macports/macports-ports/compare/master...markmentovai:macports-ports:gcc14_xcode16 addresses this locally for me. I’ll investigate a bit more to see whether this is appropriate for upstream (it probably is) or if it should be a MacPorts-local patch.

[cjones051073 (Chris Jones)]

Thanks. Please do as I suggest, open an issue with upstream at the link I posted, include a complete build log and your proposed fixed and see what he says.

[markmentovai (Mark Mentovai)]

There is already some discussion of this problem at ​https://github.com/iains/gcc-darwin-arm64/issues/136.

Replying to amake:

Thanks a lot for the tip, that works fine for me, too. I hoped that the same approach might work for octave, but when trying around with different variants, I could not find one that did not depend on libgcc14. On the other hand, I only rarely use Octave, so I will just wait for the AS_NEEDS_DASH_FOR_PIPED_INPUT fix discussed in the gcc-darwin-arm64 repo.

[BarneyStratford]

I've experienced the same problem on port gcc14 as on libgcc14. You can work around it for now on all ports affected by this bug by appending the following to /opt/local/etc/macports/macports.conf:

configurepipe no

[cjones051073 (Chris Jones)]

As a temporary measure until upstream provides a proper fix I have pushed Mark's fix above. see

[048f899dce5faab37c01ced3294fbdf74ede4f03/macports-ports]

As (lib)gcc14 is a dep for a number of ports having it broken will be an issue for many users so having this workaround, for now, is reasonable I would say.

Just for anyone playing along here... If you are doing the configurepipe no workaround, you will also want to do a sudo port clean --all gcc14 before re-attempting to port install gcc14.

[markemer (Mark Anderson)]

Also, you cannot remove configurepipe no or some things will fail when you try to use the compilers. I ran into this with gfortran

Why are ___register_frame_table and ___register_frame_info_bases missing with -reexported_symbols_list on x86 Macs but not on M Macs? What library is missing or incomplete?

These symbols, __{,de}register_frame_{info,table}*, have indeed been removed from the macOS 15 SDK for both architectures.

The GCC build for mac-x86_64 builds libgcc_s.1, but mac-arm64 does not. Observe ​x86_64 vs. ​arm64.

​GCC 7add7f7bb3d3 has more details on the provision of libgcc_s.1.

@cjones051073 @markmentovai it's not completely clear to me from the discussion above whether this is supposed to fix the builds. If so, it doesn't for me on

@cjones051073 @markmentovai it's not completely clear to me from the discussion above whether this is supposed to fix the builds. If so, it doesn't for me on

macOS 15.0 24A335 x86_64
Xcode 16.0 16A242d

This bug, as filed, about this error:

configure: error: cannot compute suffix of object files: cannot compile

is fixed for gcc14 as of ​048f899dce5f, and is now fixed on the gcc trunk at ​gcc 33ccc1314dcd. That’s sufficient to make gcc14 build and work properly on mac-arm64 with Xcode 16.

There’s a separate problem, which is not what this bug was originally filed about, concerning a handful of libunwind symbols (__{,de}register_frame_{info,table}*) that are no longer available in macOS 15 or the macOS 15 SDK in Xcode 16. These are only a factor in the gcc build on mac-x86_64.

The situation right now is that gcc14 builds and works on mac-arm64, but is still broken on mac-x86_64. This is true for macOS 15, and also for macOS 14 using Xcode 16.

I have no opinion on whether the libunwind problem should be dealt with under this bug, or a new bug should be filed. But I’m aware of the problem and intend to deal with it either way.

[cjones051073 (Chris Jones)]

As the issue in this ticket is fixed it should be closed. Please open a new one for the x86_64 libunwind issue.

[cjones051073 (Chris Jones)]

Probably the first port of call would be to open a new upstream issue at ​https://github.com/iains/gcc-14-branch/issues

[haberg-1 (Hans Åberg)]

It just failed with 'port install gcc14' on Intel, and the ticket I filed was redirected here. I will retry to see what the issue is.

[cjones051073 (Chris Jones)]

If you are on arm the issue here should be fixed so check your ports are up to date and try again.

If you are on an Intel machine there is a different issue to be addressed.

[haberg-1 (Hans Åberg)]

It still fails to build libgcc14 on Intel, as when redirected to this ticket.

The unwind problem is not specific to mac-arm64 or Iain's branch. It should be filed in upstream gcc's bugzilla. ​That's what Iain suggested.

I've researched the unwind problem and have a fix in mind, and when I have a moment, I will file it. I'll even add a new MacPorts bug to track it here, and link to it from this bug.

[haberg-1 (Hans Åberg)]

FYI, gmp currently fails on 'make check' when compiled with clang, but passes with gcc, so depending ports should use the latter.

Not relevant to this ticket. Open a new open against gmp.
