Any hints for a workaround to get configure recognizing arm64?

Building other packages (X2GoClient) are blocked by this one not playing well with M1 Macs.

I started looking at this earlier this week. I'll poke at it a little more over the weekend. I did make a little progress, but my bet is it'll take yet another patch to get Qt4 to build, and then maybe more work to get it to work on ARM64. One step at a time ...

Has duplicate #62512

comment:6 Changed 2 years ago by michaelld (Michael Dickens)

qt4-mac has yet to be fixed to work on ARM64 Macs. qt4-mac is old enough that my best guess is it'll take significant work to get it working on ARM64 -- the code just wasn't written with this architecture in mind!

I don't have time at the moment to get it working. If anybody wants to give this effort a go please do!

In the meantime, this port and its dependents should probably set supported_archs accordingly, then?

Has duplicate #62818.

comment:9 Changed 23 months ago by michaelld (Michael Dickens)

hmmm ... I added

# no support for ARM64 yet
supported_archs ppc ppc64 i386 x86_64

in [c1b160f0ad8c8d128313c22529d8382462dd3276/macports-ports] ... which should do the trick I'd think ... is there a way to call port and have it print out the value of supported_archs? Just port info qt4-mac doesn't show this info.

I finally have an M1 Mac Mini to do live testing on. The addition noted above does indeed work, in the sense that on ARM64 / M1, MP cross-builds as X86_64. That said, at least on macOS 11.5 20G70 / Xcode 12.3 12C33 there is 1 compiler error ... and asm volatile that is no longer accepted by clang. Removing the volatile does the trick, so I'm testing the patch & will push that once verified. I'm guessing removing that keyword will be OK on any ARM64 / M1, so I'm limiting its scope to just this situation.

qt4-mac: fix cross-build as X86_64 on ARM64

Closes: #61789

comment:12 Changed 12 months ago by JDLH (Jim DeLaHunt)

This fix, to cross-build as x86_64 on arm64, caused MacPorts to reinstall all qt4-mac dependencies as +universal variants, on my arm64-based MacBook Pro running macOS Monterey version 12.3.1. This it turn triggered #64933, where destroot fails on arm64 for port tiff +universal. I point this out, in case others encounter the same problem. It does not invalidate this fix.

My workaround was to abandon my attempt to install qt4-mac. As pointed out here, it is old code. MacPorts has support for Qt5 and Qt6. And, once all dependencies install successfully as +universal variants, I suppose qt4-mac as x86_64 will be usable on arm64 also, via Rosetta 2.
