zimg @3.0.4_0: requires posix_memalign

[xanda-escuyer (xanda)]

Please help with building on legacy platform.

Error experienced after running commands:-

sudo port clean installed
sudo port -Nt install ReadyMedia --enforce-variants +universal

If we understand correctly,zimg is a dependency of ffmpeg which before now has built successfully but without the +universal variant.

Any assistance appreciated; thank you.

should be fixable by a small tweak to repair this:

error: 'posix_memalign' was not declared in this scope

[xanda-escuyer (xanda)]

Thanks for taking this on. Hopefully a solution will come through in due course.

Just one more side question about the Trac Ticket please: We notice the keywords ffmpeg and powerpc have been removed. Are these just superfluous or perhaps unhelpful?

[kencu (Ken)]

the issue is unrelated to powerpc, and to ffmpeg, so those keywords were removed.

it’s only in zimg, and related to the fact that posix_memalign support came to darwin in 10.6

[xanda-escuyer (xanda)]

Ok.

The removal of ffmpeg tag makes sense; originally included here for sake of completeness because that was the preceding build. If it muddies the water then of course it needs to go.

The CPU type is G4/PPC (machine ID: ppc7450/PowerPC 7450). So perhaps the powerpc tag should be put back?

[kencu (Ken)]

yes, your machine is powerpc indeed.

but this is a failure caused by the old SDK and capabilities of the 10.5 and less system version, but is not related to powerpc specifically.

zimg: use legacysupport for posix_memalign

closes: #65746

[kencu (Ken)]

that should do it. please let us know if any other failures now show up. They might :>

[xanda-escuyer (xanda)]

The fix does indeed build successfully:-

$: port -v installed zimg
The following ports are currently installed:
  zimg @3.0.4_0 (active) requested_variants='' platform='darwin 9' archs='ppc' date='2022-09-06T00:50:55+0100'

Thank you so much for looking after this.

Will the "Port Health" list on the details page be updated automatically, perhaps via mpstats?
