While bootstrapping gcc-12.2-pre-r1:

yeah, that does not look like something down to us

actually, I did try 14.0b3 on Intel Monterey and AFAIR that worked.

I don't have any spare h/w at the moment to use for 13beta.

iains · 2022-08-25T15:07:16Z

we do invoke the linker with "no_compact_unwind", I assume?
.. maybe that is not honoured for arm64 objects (perhaps that also explains some of the unwind fails we see in the c++ testsuite). It would be useful to be able to look at the sources for a more recent ld64 to see what it is expecting.

fxcoudert · 2022-08-25T15:08:52Z

Yes we invoke the linker with no_compact_unwind, and a lot of other flags. I just wanted to have a minimal reproducer of the crash.

iains · 2022-08-25T15:12:57Z

good, that indicates that the flag is honoured but the problem remains.

<aside> FWIW, I did spend some time trying to figure out what is blocking the FSF unwind frame stuff from working with cc1as + l64 compact unwind .. and it seems that there are some problems in both places .. hopefully, I will get a chance to revisit it at some point .. </aside>

14.0b3 seems to have @(#)PROGRAM:ld PROJECT:ld64-819.1.2 I try to re-test with that on Intel Monterey (as noted before, AFAIR it was working).

iains · 2022-08-25T16:46:09Z

BTW: the 13.0 SDK in 14.0b3 does not work with GCC ... has that been fixed ? (/me has not got around to d/l latest CLT yet).

iains · 2022-08-25T16:47:57Z

Apparently, not an Arm64-specific issue ...

the 13.0 SDK in 14.0b3 does not work with GCC

Have they again included some nonstandard construct in the headers? Do you have an example/idea of where the issue is? I can report it, but we should do it soon, so it gets fixed.

iains · 2022-08-25T16:56:44Z

I will d/l latest and try it .. the fail happens before the ld64 one so that's not a blocker.

fxcoudert · 2022-09-11T17:31:52Z

The linker crash (FB11369327) has a fix being tested by Apple
The SDK header issue (DECLARE_CONSTRAINED_PTR_TYPES) is now known as FB11474414, and a fix is also being tested.

I don't understand any much of it , but if someone can guide me how to get rid of this error , then that would be very helpful !
Looking forward for the replies !
I am a beginner in C++ , and i use sublime text 3.0 to code basic DSA Questions !
While i was solving some of the questions , the error came in and i am struggling till now !

Going back for now to the previous Command Line Tools for Xcode 13.4 (or full Xcode if you need that, but I didn't try it), which can be downloaded from Apple here (note: free Apple Developer account required), did it for me.

The same "fix" sorts out PR106961, at least on x86_64 - aarch64 to be tried later!

Hey i have installed the Command Line Tools for Xcode 13.4 from Apple. Till now i haven't got the error yet , but if it happens i will inform you here brother.
Thanks for the help , really grateful to you !

mathomp4 · 2022-09-22T16:24:29Z

Hit this myself today. Does anyone know if 14.1 Beta fixes this issue? I'm trying to work out the right request for my admins, i.e., "Downgrade XCode" vs "Upgrade XCode".

Or can I keep XCode 14 (I don't do any apple development, just have it for clang), and just install/downgrade the command line tools?

gerlero · 2022-09-22T16:29:02Z

Does anyone know if 14.1 Beta fixes this issue?

I did try the Command Line Tools for Xcode 14.1 beta (dated Sep 14) before downgrading and ran into the same bug. Only the downgrade worked for me.

matteocorti · 2022-09-22T16:29:26Z

Testes with 14.1 and I still get the error.

mathomp4 · 2022-09-22T16:31:22Z

@matteocorti @gerlero Dang, thanks. Can you just install 13.4 on top of XCode 14? Or do you need to go full downgrade?

simonjwright · 2022-09-22T16:36:05Z

@matteocorti @gerlero Dang, thanks. Can you just install 13.4 on top of XCode 14? Or do you need to go full downgrade?

If you didn’t want to downgrade both, you could probably do

xcode-select -s /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk

(maybe only need /Library/Developer/CommandLineTools?)

3719e04 · 2022-11-01T15:59:24Z

please help me, i am using vscode and having this error?(m2 air macbook air)

Please see the comments above #6 (comment)

clang-15 doesn't work, boost is failing to build with "error: builtin __has_nothrow_assign is deprecated; use __is_nothrow_assignable instead [-Werror,-Wdeprecated-builtins]". clang-8 works on Mac OS 12 but not in Mac OS 10 and 11. Switching to clang-9 in those. gcc doesn't work on Mac OS 13 ATM due to iains/gcc-12-branch#6, so I disabled it there (relying on the CI tests with Mac OS 12 instead).

Due to iains/gcc-12-branch#6 (comment) g++ with XCode CLT 14.0.0 doesn't work.

We now test AppleClang 14 on Mac OS X 12. Due to iains/gcc-12-branch#6 (comment) , we test g++-11 on Mac OS X 11 till the XCode CLT issue is fixed github's side

I'm on Xcode 14.1, and have the issue with /usr/bin/ld being broken. Arm.

iains · 2022-11-27T16:19:51Z

I'm on Xcode 14.1, and have the issue with /usr/bin/ld being broken. Arm.

I have just built gcc-12.2-pre-r1 and current gcc-master (on aarch64-darwin21 [arm64 macOS 12]) using XC 14.1 command line tools, without any problems. As far as I can tell, the linker bug is fixed there [and in the 14.1RC, in fact], so you will need to analyse your problem and provide some more details.

WildUtah · 2022-12-02T03:56:42Z

I'm on Xcode 14.1, and have the issue with /usr/bin/ld being broken. Arm.

Just installed Xcode 14.1 command line tools and re-installed gcc-12 from homebrew.

@WildUtah please file an issue at Homebrew with a full report (source compiled, exact command line, etc)

iains · 2022-12-03T21:26:43Z

is there any insight here? (my builds are working).

ilg-ul · 2022-12-15T07:53:01Z

Does CLT 14.2 fix this issue?

helmesjo · 2022-12-18T16:49:07Z

@ilg-ul Supposedly it should (I've read 14.1 beta 3 had the fix), but I just installed Command Line Tools 14.2 (and verified installed version) to no success. Note: I'm building with apple-clang.

iains · 2022-12-18T17:15:28Z

hmm.. I cannot repeat this (it does not seem to be a GCC issue anyway, but...)
can you please post exactly what you are doing (in terms of installed tools, PATH and configure line).

output of clang --version
ld -v
also please (not that I can necessarily help, since AFAICT the problem is fixed)

helmesjo · 2022-12-18T18:24:56Z

Actually, I'm confused... I installed Command Line Tools 14.2 as mentioned (making sure to nuke the previous install first), but I keep seeing clang version 14.0... Are these version numbers not tied? I'd expect to get clang 14.2 when installing CLT 14.2.

fxcoudert · 2022-12-18T18:29:21Z

No, Xcode 14.2 and CLT 14.2 both come with clang-1400.0.29.202

helmesjo · 2022-12-18T18:29:56Z

Go figure... Alright, thanks! That explains.

ilg-ul · 2022-12-18T21:16:41Z

So, to be sure I got it right, the linker in Xcode/CLT 14.2 still trows this assert, for example when compiling hello-exception.cpp?

helmesjo · 2022-12-18T21:31:46Z

@ilg-ul No, it was just me not understanding the versioning game Apple plays. So I was still running apple-clang 14.0. Sorry for the confusion.

iains · 2023-05-26T22:52:16Z

i think this is all ancient history now.
