Description

While trying to update p5-tk I observed CI builds fail on macOS 11 Big Sur.

/usr/bin/clang -o perlrx -fno-common -DPERL_DARWIN -mmacosx-version-min=10.16 -pipe -Os -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX11.0.sdk  -fno-strict-aliasing -fstack-protector-strong -I/opt/local/include -DPERL_USE_SAFE_PUTENV -I/opt/local/lib/perl5/5.26/darwin-thread-multi-2level/CORE config/perlrx.c  -mmacosx-version-min=10.16 -L/opt/local/lib -Wl,-headerpad_max_install_names -Wl,-syslibroot,/Library/Developer/CommandLineTools/SDKs/MacOSX11.0.sdk  -fstack-protector-strong  -c

The p5-tk port (and likely others) currently relies on the compiler and flags hardcoded in Perl itself (I am struggling to get p5-tk to completely respect custom compiler/flags settings). The MacOSX11.0.sdk directory is reportedly no longer present on an up-to-date macOS 11 system, but it is hardcoded in the already-built packages of perl5.xx ports e.g. in Config_heavy.pl. Ideally an unversioned SDK path can get hardcoded instead.

I'm not sure exactly which version of MacPorts base the packages were built with (either 2.6.3 or 2.6.4), and whether that has an effect here. I personally do not use macOS 11.

comment:1 Changed 6 months ago by jmroot (Joshua Root)

This is almost another aspect of the same underlying issue as #50894 and #59786.

We shouldn't hardcode any SDK path in Config_heavy.pl, we should delete the -isysroot and -Wl,-syslibroot flags entirely. That way any SDK specified in the environment or CFLAGS will be used, and if none is specified, the toolchain falls back to using MacOSX.sdk anyway.

Replying to chrstphrchvz:

I'm not sure exactly which version of MacPorts base the packages were built with (either 2.6.3 or 2.6.4), and whether that has an effect here.

They were built with MacPorts 2.6.4 since that is the first version that was compatible with macOS 11.

This issue probably plays into #62819 as well.

Reported again for p5.28-tk: #62915

comment:5 Changed 3 months ago by ryandesign (Ryan Schmidt)

This would be a good issue to fix before the bulk add of p5.34 ports, since not fixing it causes many build failures on macOS 11.

This has been a longstanding issue and I would be grateful for some basic hints about the best solution. Here's what the file /opt/local/lib/perl5/5.28/darwin-thread-multi-2level/Config.pm currently contains for 5.28 on 11:

# This file was created by configpm when Perl was built. Any changes
# made to this file will be lost the next time perl is built.

# for a description of the variables, please have a look at the
# Glossary file, as written in the Porting folder, or use the url:

I have a question for other mac gurus (I haven't been following version 11 too closely). Perl is currently built in the following way:

My questions are as follows:

  • Is passing /Library/Developer/CommandLineTools/SDKs/MacOSX11.sdk in fact needed in order build (any given) software correctly or is it there "just in case"?
  • I see that we are now passing MacOSX11.sdk to compiler flags (which is just a symlink to MacOSX11.x.sdk), while this used to be MacOSX11.0.sdk at the time when perl was built. Wouldn't thus this problem be fixed without any further changes if we simply revbumped perl?

I'm not saying that this doesn't need to be addressed at some point, I'm just trying to find some quick solution to overcome the painful problem on macOS 11.

I opened an upstream ticket:

comment:8 Changed 3 months ago by kencu (Ken)

Jeremy has indicated previously we should really not be passing as arguments or embedding any paths to an SDK into build scripts or files at all.

If we want to force a specific SDK, set SDKROOT.

https://github.com/macports/macports-base/pull/147

If you don't set SDKROOT, then xcrun will find an appropriate one for you when you run clang.

comment:9 Changed 3 months ago by mojca (Mojca Miklavec)

I just tested on macOS 11/arm64 and solely revbumping perl5.32 (meaning that MacOSX11.sdk gets hardcoded into Config files rather than MacOSX11.0.sdk) leads to successful installation of p5.32-tk, for example.

Ken, one part that I'm not sure about when reading your answer: are you (and Jeremy) saying that:

  • we should never pass any SDK to CFLAGS, LDFLAGS, ... (apparently the base does exactly that)
  • or that we should not bake those values into build scripts

I totally agree with the second item, but at this very moment it's a tiny bit non-trivial to fix this "in a correct way" unless we also remove SDKs from all the environmental variables, so that perl5.x never even sees the path to SDK (and thus it also won't store it anywhere).

I believe we should look at this from two completely different angles and try to find:

  • something that fixes the problem immediately
  • something that fixes the problem correctly

At this moment I would like to solve the first one. We need to talk to upstream to address the second one.

Replying to mojca:

For anything to do with clang or Xcode, I believe we are supposed to set SDKROOT and try to leave the isysroot stuff out of the flags.

It might be that there are considered to be too many fringe cases to allow this, like maybe nasm and such. I don't know if all those fringe compilers respect SDKROOT.

  • or that we should not bake those values into build scripts

We do see troubles when baking an SDK path into various installed scripts, and later the SDK path changes.

It seems to me that there is often no advantage to burning in these paths, and we might do best to leave them out.

Then either our set SDKROOT in the environment would dominate, or as a final backup, xcrun would find an SDK (the most current one).

Except that isysroot was added by Jeremy in 8863962b perl5 pg: use correct sdkroot to fix #59131 and #59154?

It's possible that something either was or still is added by portconfigure.tcl, at least on >= darwin19.

We do see troubles when baking an SDK path into various installed scripts, and later the SDK path changes.

Sure, we need to avoid this.

It seems to me that there is often no advantage to burning in these paths, and we might do best to leave them out.

I totally agree. I'm just saying that it's a tiny bit non-trivial to remove them all out from Config.pm and Config_heavy.pl without upstream helping at least a bit. To me, by far the easiest solution seem to be removing them from environmental variables before building perl itself. I'm just not sure if I'm allowed to do that.

Replying to mojca:

  • Is passing /Library/Developer/CommandLineTools/SDKs/MacOSX11.sdk in fact needed in order build (any given) software correctly or is it there "just in case"?

Not at present, but that will change as soon as Xcode starts defaulting to using MacOSX12.sdk. And of course if a user wants to use any other non-default SDK, you need to tell the toolchain about it.

  • I see that we are now passing MacOSX11.sdk to compiler flags (which is just a symlink to MacOSX11.x.sdk), while this used to be MacOSX11.0.sdk at the time when perl was built. Wouldn't thus this problem be fixed without any further changes if we simply revbumped perl?

The problem would be hidden in the common case, sure.

Resolution: fixed
Status: assignedclosed

In f35a2c53331234cc730b090b1b866d4b1702a747/macports-ports (master):

perl5: address problematic baked-in values

Use generic /usr/bin/cc for compiler since the specific one used to
build perl may not be available at runtime. Remove flags specifying SDK
and deployment target since different ones may be specified in the
environment at runtime, and, similar to the compiler, the SDK that was
used at build time may not be available at runtime.
