comment:1 Changed 2 years ago by ryandesign (Ryan Carsten Schmidt)

It is unusual that it is trying to link with the static library libxml2.a. It should be linking with the dynamic library libxml2.dylib. Once that is fixed, the undefined symbols should disappear.

The meson log says the reason is: 

Rejected /opt/local/lib/libxml2.dylib, supports ['ppc7400', 'ppc64'] but need ppc

It is "normal" for software to build for ppc7400 (G4) when -arch ppc is used on a system version that does not support G3 processors. Maybe meson is not aware of that and needs to be enhanced to deal with it.

Could you suggest what should I try to do?

  1. S. Notice a similar error with gobject-introspection that uses meson now: ​https://trac.macports.org/ticket/64769

read through the meson source code. It’s written in python, so easy enough. Find some part where it is examing the architecture of dependent libraries. Fix it to not error with the ppc7400 issue. Possibly submit the fix upstream.

Or, just open an issue with meson and see if they will fix it for you. Don’t hold your breath there, but….

Or, ask Evan to fix it. He only has a G3 though, so doesn’t see this error and can’t test it….

Replying to kencu:

read through the meson source code. It’s written in python, so easy enough. Find some part where it is examing the architecture of dependent libraries. Fix it to not error with the ppc7400 issue. Possibly submit the fix upstream.

I have fixed meson:

Description: modified (diff)
Owner: set to RJVB
Status: new → assigned
Summary: shared-mime-info fails to build for ppc64 on Leopard → shared-mime-info fails to build for ppc64 on Leopard: need to add muniversal PortGroup
Version: 2.7.1 → 2.7.2

well done -- that does look like a correct fix, indeed.

LGTM.

EDIT: I see my own copy has gotten quite a bit behind, and only contains the executable to update the database. If that's still the case in newer versions I'm not sure what the point is to build this port with +universal?

I am sorry, do you mean shared-mime-info? It is a dependency for libheif and few other ports, not an aim in itself. I guess adding muniversal won’t hurt? At least conditionally, like “if variant is set universal”?

comment:9 Changed 2 years ago by RJVB (René Bertin)

Yes, I meant the port under discussion, shared-mime-info. A port that is a dependency of others doesn't *have* to have a +universal variant to allow the dependent to install in universal build. In a sense it's actually better if it doesn't have the variant, to limit unnecessary propagation of universal installs (which take place and usually increase upgrade times).

Honestly I do not know if in this case +universal matters for dependencies. You are right, in some case it does not, however certainly not in every such case.

comment:11 Changed 2 years ago by RJVB (René Bertin)

A priori, +universal is only required in a dependency if it contains a shared library, plugin or anything else that is supported by Apple's fat binary architecture and that has to contain the correct architecture(s) in order to be used by the dependent, or if they have to be able to produce such components for the dependent.

I'll have to upgrade my own version of the port to affirm whether it now contains components that require universal support. It shouldn't if it still only contains the standard mime info files (text) plus a helper to compiles a cache from those files plus whatever others are installed.

Caveat emptor: the mime.cache file is a binary, identified as "PFM data" by my file command. I don't know what that is and it *might* not be cross-platform. This could be a problem if you're running 32 and 64 bit applications simultaneously, and there'd be very little we'd be able to do about that. But I think we'd know that by now...

I just upgraded my copy to v2.2 and can confirm that

  • there's still only a helper application in this port, no shared libraries for working with the mime files
  • building +universal with the muniversal PG works on Intel too
  • running the i386 (32b) version or the x86_64 (64b) version of update-mime-database leads to bit-identical $prefix/share/mime/mime.cache files. Sadly I cannot verify if the file is also endian-agnostic (but are there any users installing arm+intel fat binaries?!)

Ok it seems ppc970 is a valid case too, so having it makes sense. Example: ​https://groups.google.com/g/hugin-ptx/c/uWSPhl1MjCc

My PR got merged into upstream: ​https://github.com/mesonbuild/meson/pull/10258 We will need to move to meson 0.62.1 though once it is out.

  1. S. Turned out ppc970 is still ppc32, just optimized for 970: ​https://opensource.apple.com/source/cctools/cctools-836/cctools-836/libmacho/arch.c
