net-snmp build fails on arm64 Undefined symbol _vm_region

[p-b-west (Peter West)]

In the process of building gimp, build of net-snmp fails.

:info:build Undefined symbols for architecture arm64:
:info:build   "_vm_region", referenced from:
:info:build       _pages_swapped in memory_darwin.o

I'm also experiencing this error as a dep of sane-backends. Is there any additional information or testing that would be helpful in resolving this?

[fracai]

I was able to get this a bit further by modifying: .../work/net-snmp-5.9/agent/mibgroup/hardware/memory/memory_darwin.c:81 to add || defined(__aarch64__) to the end of the line.

Then the port fails with:

This looks similar to: #62227, #59951, #62440. So maybe a similar fix?

Thanks, I'll look into that. Is there an upstream bug report about this? If not, could you file one?

Presumably nothing beyond fixing #62440 is needed. Until that's done, you can rebuild perl5.28 from source using sudo port -ns upgrade --force perl5.28 but would likely need to do so again in the future (e.g. after you upgrade Xcode).

Presumably nothing beyond fixing #62440 is needed.

In fact we're tracking the issue for net-snmp separately in #59755.

[fracai]

Thanks, I rebuilt perl5.28, cleaned and extracted net-snmp, re-applied the __aarch64__ definition, built and installed.

I'll open an upstream issue.

[fracai]

Actually, it looks like there's already a resolved issue filed against the more recent 5.9.1 release.

​https://github.com/net-snmp/net-snmp/issues/295

Which is linked to the homebrew PR: ​https://github.com/Homebrew/homebrew-core/pull/78122

It looks like just running autoreconf -fvi prior to ./configure allows a successful build.

This was outside of MacPorts so I'm not sure if the configure flags or patches would need to be changed as well.

That issue is not resolved, and it regards the error:

checking build system type... Invalid configuration `aarch64-apple-darwin20.4.0': machine `aarch64-apple' not recognized

which is not the error you reported. That issue could indeed be fixed by using autoreconf or maybe just using a newer config.guess & config.sub.

The error you reported was fixed in 5.9.1 in ​https://github.com/net-snmp/net-snmp/commit/bcc654e704f4794a9b10b8abf6e01f509402a6d3.

Yep, just built and installed fine for me. Thanks for the updates.
