We'll need more information. Could you attach the main.log file, please? It does sound like something that's been reported before (I remember seeing the erroneous reference to ppc archs on arm64 before) but I can't find it right now.

[jmroot (Joshua Root)]

There's a part in the Portfile where it tries to figure out which archs can be run on the build machine. It looks like this code doesn't account for arm64 systems.

Yep. And ideally we shouldn't need it, if we could leverage what's already being done by muniversal.

So I could use some advice/guidance on this, from you more Universal-savvy folks:

• The port is based on muniversal 1.0. Would migrating to muniversal 1.1 assist at all with this?
• Suggestions on how to eliminate the logic in question?

I did a port update and attempted an install of gtk3-3.24.38 again. This time I got a different error:

Thanks for the update, and the log file.

I'll try to find some time to test and fix this, over the next few days. More to follow.

[Liontooth (David Liontooth)]

Hi Chris! You're no doubt a busy man. I'm still getting

unknown target 'CC=/usr/bin/clang -arch arm64'

Why isn't this particular package familiar with arm64? Since we're building for arm64 all the time, what is it that gtk3 is doing that makes the ninja build tool not recognize the target?

Build failure on arm64 with --build-tool=ninja ​https://github.com/randombit/botan/issues/3750 is reported fixed for botan with Fix Ninja build to pass instruction set flags to the compiler ​https://github.com/randombit/botan/pull/3751.

​https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=f84e0bd3e7f13888c343883bbc5e0b26b0694bf3 shows the details, involving

this is still dying building universal on arm/Intel...

[gregyao]

Still dying building universal on arm/Intel: it fails for me when install kdelibs4 tries to install gtk3 as a dependency. Would be grateful for any help. Thanks

[Liontooth (David Liontooth)]

Yes, this is now blocking all updates for me

[kencu (Ken)]

If you don't really need gtk3 to be universal, just install it non-universal and you're good to go.

If you believe you really do need it universal (you probably don't), you are out of luck for the foreseeable future as nobody appears motivated to fix it, now three years after arm Macs came out.
