In my case it's _panic_stage:

Interestingly this only reproduces using MacPorts's LLVM. I don't see it when building from source…

[i0ntempest]

We have different problems then, for me it fails even in a manual build. Also see: ​https://github.com/ziglang/zig/issues/11920

[saagarjha (Saagar Jha)]

Just to be clear, this reproduces in a manual build too if I use MacPorts LLVM. Using a LLVM I built myself does not reproduce the issue. Just wanted to confirm that you were doing this rather than using MacPorts to get the dependencies :)

[kencu (Ken)]

I might wonder if it could somehow be connected to this commit, that enabled emulated-tls for all llvm/clangs:

[1624fe05a9a4301b52b76ef157f4ec63378338d9/macports-ports]

I can't see, at the moment, how else that symbol could be creeping into the build.

[saagarjha (Saagar Jha)]

Removing "0019-10.6-and-less-use-emulated-TLS-before-10.7.patch" from llvm's Portfile fixes the issue. From the patch I'm not entirely sure why because it seems to not make changes on <10.7, but I'm sure Ken can work it out from there :)

[i0ntempest]

Just confirmed, it's indeed caused by that patch. If that patch is supposed to change stuff on 10.7 and earlier maybe we could apply it only on those systems for now?

[kencu (Ken)]

well, that’s how it was before, but Marcus had to change it to apply on all system versions to fix an issue with rust.

I think then somehow this added condition is leading llvm to tell zig to use emulated tls?

​https://github.com/macports/macports-ports/blob/e8ee22994285a56f684af1ddf7841051378f1410/lang/llvm-13/files/0019-10.6-and-less-use-emulated-TLS-before-10.7.patch#L52

If that is the exact issue wonder why this test is isMacOSXVersionLT(10, 7) is misbehaving… have to find and read over exactly how that is set.

[i0ntempest]

Any news on this? If the emutls patch file cannot be removed maybe put it into a variant or something?

[i0ntempest]

In 79cdca7883640b43b03f0b216de0e1a56df0db0f/macports-ports (master):

zig: update to 0.10.0, add lib dependencies

Closes: #65333

[i0ntempest]

Looks like after the 0.10 upgrade, arm builds are getting the _panic_stage symbol not found error:

Undefined symbols for architecture arm64:
  "_panic_stage", referenced from:
      _std.debug.panicImpl in zig2.o
  "_panic_state_raw", referenced from:
      _crash_report.PanicSwitch.preDispatch in zig2.o
      _crash_report.PanicSwitch.dispatch in zig2.o
  "_zir_state", referenced from:
      _crash_report.AnalyzeBody.push in zig2.o
      _crash_report.AnalyzeBody.pop in zig2.o
      _crash_report.dumpStatusReport in zig2.o
ld: symbol(s) not found for architecture arm64

I don't have an arm machine so I don't know how to tackle this.

[saagarjha (Saagar Jha)]

I have an Apple silicon Mac and have been running with a patch that removes the TLS fix for 10.6 for several months without problems. I don't actually know what the difference is but considering it works, perhaps we can make it conditional on OS like it was before?

[kencu (Ken)]

I think zig must monkey with the target triple… how else??

but you would imagine that would cause lotsvof fallout…

[kencu (Ken)]

what to do…

removing the tls patch for arm would probably practically do the zig fix, but it’s undesirable for systems to diverge like this. llvm built universal arm64/x86_64 on arm would be different than llvm built universal on Intel

fixing zig seems impossibly difficult to ask, given what we’re doing to llvm here.

​https://github.com/ziglang/zig/issues/11920

making zig use it’s own sequestered llvm is inefficient and a maintenance burden…

[breun (Nils Breunese)]

I ran into this issue when trying to install the ncdu port on arm64, which has zig as a dependency. I see this ticket is closed. Does that mean this issue should be solved now? Because it's not solved for me, see ticket:66173.

That's a different error, though might be caused by the same thing (the emutls patch for llvm).

[kencu (Ken)]

has duplicate 66173

[ryandesign (Ryan Carsten Schmidt)]

Has duplicate #66766.

[mforbes (Michael McNeil Forbes)]

Is there a workaround? I really want to be able to use ncdu and this is breaking for me. It is not clear if a workaround is posted elsewhere, but it is certainly not easy to find. Is there some easy way to regress?

[kencu (Ken)]

I think this error is happening with our llvm patch because with our patch, llvm might call for the emulated tls symbol.

zig checks to see if the symbol exists, therefore, and doesn’t find it, so errors.

see

​https://github.com/ziglang/zig/issues/8180

and

​https://github.com/ziglang/zig/commit/dbfcebf8d88b91c5a85366da09a4ce69c0bb5dc6

We might be able to tell zig not to error when it can’t find

'___emutls_get_address'

by passing a linker flag.

[kencu (Ken)]

this flag

-fallow-shlib-undefined

might do it, however it might then allow other, needed, undefined symbols to not error… have to see

[kencu (Ken)]

Well, adding:

configure.ldflags-append -Wl,-undefined,dynamic_lookup

didn't work:

ld: warning: -undefined dynamic_lookup may not work with chained fixups
ld: illegal thread local variable reference to regular symbol _panic_stage for architecture arm64

[vigna (Sebastiano Vigna)]

Removing 0019-10.6-and-less-use-emulated-TLS-before-10.7.patch worked for me.

[kencu (Ken)]

Yes, problem is we can't really remove that patch without sinking the rust ports, so we're trying to see if we can get zig to work even with that patch in.

Otherwise we will need a sequestered llvm for zig I guess.

[saagarjha (Saagar Jha)]

Can we look into why this patch is breaking the build? As far as I understand it was intended to be a no-op for anything past 10.7. Can we not make it do this?

look up for my thoughts on this, links to relevant issues, and potential solution paths:

[mforbes (Michael McNeil Forbes)]

Since no one has provided a workaround yet for this, I have posted one for my particular issue with ncdu:

# Make some coffee... this takes a while.
git clone --single-branch https://github.com/macports/macports-ports.git  
cd macports-ports
git checkout 6032b8aa0e865ddedc83b63bc662c7e5e091a909
cd sysutils/ncdu
port install

This will install version ncdu@2.2.1 which uses the previous version of zig.

Don't forget to exclude this when you upgrade:

port upgrade outdated and not ncdu

[saagarjha (Saagar Jha)]

You know you can tell MacPorts to index a git repo, right? I have a couple of patches that I apply and it manages rebasing them for me on each update. See ​https://guide.macports.org/#installing.macports.git for how to switch over.

[breun (Nils Breunese)]

If you want to use ncdu, and don't necessarily need ncdu 2.x, you can run sudo port install ncdu1 to install ncdu 1.x, which doesn't require zig.

[maverickwoo (Maverick Woo)]

FWIW, I was just able to build zig 0.11.0 with the latest ports of clang 16 and llvm 16 on arm64 with macOS 12. This subsequently allowed me to build ncdu 2.3 on the same machine.

For the purpose of reproducibility, here are the small changes I've made to my local Portfiles:

[...]

                        size    56608
[...]

P.S. I am aware that this does not solve the problem that zig 0.10.1 does not build on the same machine (which I could also reproduce), but I thought this message may be useful for future visitors of this ticket. (I arrived here originally through ncdu.)

[maverickwoo (Maverick Woo)]

I submitted a PR (​https://github.com/macports/macports-ports/pull/20090) to upgrade the zig port to 0.11.0. If merged, it will sidestep the issue of 0.10.1 not building and then I will submit a PR to upgrade ncdu as well.

[maverickwoo (Maverick Woo)]

In bf8204b0ff254e55b1e48ee9498880c7184c6893/macports-ports (master):

zig: update to 0.11.0

See #65333.

Note:

The use of "PortGroup cmake 1.1" would lead to a dependency on the
existence of ${prefix}/share/cmake/Modules, but this directory may not
exist on some machines (such as the CI). We workaround this by
piggybacking on a directory that is known to exist due to the build
dependency on LLVM by this port.

[vigna (Sebastiano Vigna)]

Unfortunately, does not build again with Sonoma, even using 0.11.0 and removing 0019-10.6-and-less-use-emulated-TLS-before-10.7.patch from llvm-17.
