Please sudo port clean python39 and try again, now that you have fixed your llvm-7.0 libffi problem.

[metbic]

Good morning.

I did and python39 still does not build. llvm built fine (libidn still won't build neither).

This issue looks similar: ​https://github.com/pyenv/pyenv/issues/1267

Your configure file says: configure:6095: found /opt/local/bin/ar

So I would try:

port upgrade cctools

And if that doesn't work

port deactivate cctools

Then clean and rebuild python39.

Upgrading cctools was only possible via port upgrade inkscape, trying to upgrade it via port upgrade cctools triggered the broken ports search and the rebuild wishlist, then, after hitting Y, the first port that gets rebuilt is python39 and that fails to build. Then, I did another clean python39 and upgrade python39, no results. Error logs of this 3rd try are attached.

[ryandesign (Ryan Carsten Schmidt)]

At the moment it looks like this failure is specific to the +universal variant. I'll leave it to Josh to puzzle it out, though there are a couple other open tickets about problems with python universal variants already.

If you don't need python39 to have the universal variant, install it without that variant.

[metbic]

I tried that and it seemed to work. I cleaned python39 and did a simple sudo port install python39 and it went through the build process successfully.

[ryandesign (Ryan Carsten Schmidt)]

Duplicate #64719 says the problem affects python310 too.

[metbic]

As stated above, the issue with python39 could be solved without the universal option. Is this maybe also feasible regarding python310? Is there a way to install python310 without universal? I'm not sure how the command syntax should be used to achieve that.

[metbic]

I'm asking this since a simple install python310 is not enough to install it without universal option.

As before, I try to install it without universal.

After typing sudo port install python310, a broken port analysis is performed and recommends to rebuild glib2, and in order to do that, python310 is automatically installed with the universal option and this again fails.

Can I somehow instruct the automatic installer to do it without universal, maybe with a global no-universal system variable or anything?

[jmroot (Joshua Root)]

Upgrading will only automatically add +universal if something else requires it. See port -v installed dependentof:python310 to help figure out what that is.

Can anyone test whether this also happens on other OS versions? And also whether -lto or -optimizations make any difference?

[metbic]

 port -v installed dependentof:python310
The following ports are currently installed:
  asciidoc @9.0.4_0 requested_variants='' platform='darwin 14' archs='noarch' date='2021-01-19T12:05:06+0100'

  ninja @1.10.2_4 (active) requested_variants='' platform='darwin 14' archs='x86_64' date='2022-02-21T18:01:46+0100'

The only one of those that has additional downstream dependants is ninja, meson depends on ninja. I will try now to disable all three dependants (asciidoc,boost176,ninja) and to install python310 then.

[metbic]

Still the same as in ​https://trac.macports.org/ticket/64708#comment:10, glib needs python310 with the automatic universal option and this breaks the process. I don't know if disabling glib2 is a good idea, since so many ports will break if I do this.

I cleaned glib2 and installed it without universal, and now even more ports are broken (including wine-devel, and I must say, this starts to hurt now), while python310 still won't build.

[jmroot (Joshua Root)]

OK, wine-devel explains a lot, it's 32-bit and so all its dependencies have to be universal if your normal build arch is x86_64.

[metbic]

Replying to jmroot:

Would you say the other trouble I'm experiencing ​https://trac.macports.org/ticket/64620 are universal-related too?

[jmroot (Joshua Root)]

In 063f7f7fb012ec6cf36f0ca1f69b8c285a62947f/macports-ports (master):

python39: don't add +lto to +universal on < 10.11
