cmake: build failure on macOS 15: stale libxml2, still linked to icu 74

[josmithiii]

port install cmake fails with

port search icu only shows version 76.1 available.

[mascguy (Christopher Nielsen)]

The issue is actually libxml2.2.dylib, which is still linked to the older version of libicu. Can you run port -v installed libxml2, and paste the output?

[mascguy (Christopher Nielsen)]

After that, can you run sudo port rev-upgrade? That should catch broken binaries like this, and rebuild components as necessary.

[ryandesign (Ryan Carsten Schmidt)]

The revisions of libxml2 and other ports linking with icu were increased 11 days ago specifically to rebuild them with the new icu so this problem should not occur if your ports are up to date.

Sure, thanks:

Some things I tried:

Maybe libxml2 should try to depend on cmake-bootstrap instead of cmake? I have that installed ok.

[ryandesign (Ryan Carsten Schmidt)]

Ok, so a dependency cycle exists; MacPorts doesn't support dependency cycles.

libxml2 doesn't use cmake at all. But libxml2 depends on icu which (at least on my macOS 12 machine) depends on clang-17 which depends on cmake which depends on libarchive which depends on libxml2.

[mohd-akram (Mohamed Akram)]

ICU shouldn't depend on MacPorts Clang on newer versions of macOS, and for older versions it should use clang-bootstrap. I'm on macOS 15 too. If I do port info icu it shows clang-19 as a build dependency, but if I do port info inside the icu directory I don't see it. I also don't understand why it depends on clang-17 for you Ryan instead of clang-19.

[ryandesign (Ryan Carsten Schmidt)]

Replying to mohd-akram:

If I do port info icu it shows clang-19 as a build dependency, but if I do port info inside the icu directory I don't see it.

Hm, yes I see that too (with clang-17 instead of clang-19). port info icu consults the PortIndex; port info in a port directory consults the Portfile.

The PortIndex files are generated on a machine running OS X 10.11. Maybe the method that mprsyncup​ uses to fake the OS version is insufficient; it just gives portindex​ different platform values in the -p flag.

I also don't understand why it depends on clang-17 for you Ryan instead of clang-19.

I'm on macOS 12. MacPorts only offers clang 18 and later to macOS 13 and later:

[mohd-akram (Mohamed Akram)]

Thanks Ryan. It doesn't actually try to install clang-19 for me when I try to install icu though, so I'm not sure why OP is getting that issue. The revision of libxml2 is also correct so it should have linked against icu 76. I would try uninstalling libxml2 and installing it again. If that fails, post the log here.

[mascguy (Christopher Nielsen)]

Port libxml2 was just updated a few days ago. Is this still an issue?

[josmithiii]

port install cmake works now, thanks

Great, thank you for confirming!
