Have you followed the guidelines for contributing?
Have you ensured that your commits follow the commit style guide?
Have you checked that there aren't other open pull requests for the same formula update/change?
Have you built your formula locally with brew install --build-from-source <formula>, where <formula> is the name of the formula you're submitting?
Is your test running fine brew test <formula>, where <formula> is the name of the formula you're submitting?
Does your build pass brew audit --strict <formula> (after doing brew install --build-from-source <formula>)? If this is a new formula, does it pass brew audit --new <formula>?

Continuation of #100411, since rebasing that was a little tricky.

CC @fxcoudert, in case this is not a good idea.

I think it's a good idea, and I cannot see any drawback. But, this is a subtle issue, so I might be overlooking something 😄

Yes, it's the subtle issues that I'm concerned about. Ah well, hopefully nothing 💥s

@iMichka @danielnachun I don't know what this does, so would be good to check that this makes sense.

I'm also not clear on why we don't want opt_lib here, as in opt_lib/"gcc/current".

We can clean this up in a second step as this is in the postinstall block.

current looks ok to me given the other changes to gcc made here.
There are some explanations above: the spec file just makes sure the right -L flags are passed when using brewed gcc (without shims, so when you want to compile your own stuff locally). With this our users don't need to set the -L flags manually for the internal gcc libraries.

As to why not using opt_lib: why not, might be worth a try.

    # Provide a `lib/gcc/xy` directory to align with the versioned GCC formulae.
     (lib/"gcc").install_symlink "current" => version_suffix

I'm wondering if we really need to do this. I don't think anything inside Homebrew relies on this, and I think it's more confusing to add a duplicate tree structure (especially since we cannot have a single symlink).

carlocab · 2022-07-30T10:14:36Z

I would find it pretty confusing to have a lib/gcc/{9,10,11} but no lib/gcc/12.

If we don't want the symlinks, why not just make it lib/gcc? The extra current directory seems entirely superfluous then.

Maybe as additional context, this is really motivated by the directory structure you find in a typical macOS framework. There, you have a Versions directory which contains the various framework versions, but also a Current symlink pointing to one of those versions (typically the latest).

If this is very confusing, we could make current really just a symlink, at the expense of slightly more code.

fxcoudert · 2022-07-30T10:21:46Z

@carlocab I see your reasoning. One point of note is that if several directories exist, we might start having stuff link to specific version numbers instead of current. But maybe I'm paranoid.

carlocab · 2022-07-30T10:40:31Z

No, the linker will use the library install names, which reference current and not the version number (because that's what we used for --libdir).

In particular, you can do something like

clang foo.c -L$HOMEBREW_PREFIX/lib/gcc/12 -lgcc_s

and yet you will still link using the current directory.

On Linux all that matters is the RPATH.

Looks like we need all the revision bumps from #100411. Let me cherry-pick those and re-add the ones that get lost because of changes on master.

If someone could help me make sure I didn't lose any commits from #100411, that'd be much appreciated.

Dropped gcc@11 so we can get a better sense of what's broken on Linux. I was hoping to run Intel tests to the end, but it's now taking too long.

carlocab · 2022-07-31T12:06:03Z

augustus is probably broken, and digging into some Git logs suggests it's been that way for some time: #40220

If it fails again I don't think it should block merging this.

There is a Linux openblas test failure :(

There is a Linux build failure of octave (might be related, not 100% sure).
Linux build failure of kim-api

In addition to the first PR removing Linux-only dependencies that fail at #106926 here is a list of failures in the previous (unfinished) run: cgl chakra chapel clazy clp coinutils csound dlib dpp eigenpy enzyme faiss fibjs gnustep-base igraph jags julia lc0 ldc libobjc2 libsigrok lit llnode llvm llvm@13 mesa minizinc nu objfw odin or-tools rtags scs. I'm going to open another PR for those, see which ones depend on gcc and which are due to some other issue.

There is a Linux openblas test failure :(

Some Googling suggests this could be a consequence of running strip on the shared libraries. Does openblas do this during the build? If it does, can we convince it not to?

gdb: #107389

qt just hardcodes a reference to gcc-11 as its compiler. We can't afford a qt rebuild whenever gcc gets a major version bump. gcc-current? 😂

My guess is that this covers the rest of the qt dependents too: anything that starts with q, plus treefrog.

verilator is not a Qt-dependent, but it also hardcodes g++-11.

llvm@13 looks like #107018.

@iMichka / @carlocab : Just noting that I see the Chapel checkbox on the list above and am checking to see if I can find someone on our team to help with it, if that would be helpful.

carlocab · 2022-08-05T17:34:27Z

That would be very helpful, @bradcray, thanks so much. To be clear, the macOS builds are fine. It's the Linux build that seems to have issues.

@carlocab: Saw that, thanks for making sure.
@cho-m: We've been seeing and working on diagnosing related failures on some local M1 builds lately, so hopefully it's the same root issue for all cases. Thanks for making us aware of those cases, which I hadn't been aware of.
