qemu @8.0.4: ERROR: No host machine compiler for 'audio/coreaudio.m'

Reported by: barracuda156 Owned by: raimue (Rainer Müller)
Priority: Normal Milestone:
Component: ports Version: 2.8.1
Keywords: Cc: evanmiller (Evan Miller), cooljeanius (Eric Gallager)
Port: qemu

Description

When I try building qemu, I get the following configure error:

../qemu-8.0.4/meson.build:3420:13: ERROR: No host machine compiler for 'audio/coreaudio.m'

I tried to disable coreaudio altogether, passing --disable-coreaudio, but then it fails a step further with:

../qemu-8.0.4/meson.build:3810:58: ERROR: Tried to access compiler for language "objc", not specified for host machine.

Because Meson script coerces Obj C on Darwin:

if targetos == 'darwin'
  summary_info += {'Objective-C compiler': ' '.join(meson.get_compiler('objc').cmd_array())}
endif

Which is probably a bug (if no Cocoa and no Coreaudio, why ObjC?), but regardless of that, why GCC is not acknowledged in the first place?

Macports does pass --objcc=/opt/local/bin/gcc-mp-12.

I can confirm seeing this issue as well in High Sierra on Intel.

Summary: qemu configure does not recognize gcc as a valid objc compilerqemu @8.0.4: ERROR: No host machine compiler for 'audio/coreaudio.m'

It's not specific to PowerPC or GCC; it's specific to disabling the cocoa variant. Their meson build script makes the incorrect assumption that an Objective-C compiler is only required when building the Cocoa UI but it's also required to compile the CoreAudio driver regardless of the UI.

This is an upstream bug and getting it fixed could have been accelerated if someone had reported it to the developers. I've reported it there now: https://gitlab.com/qemu-project/qemu/-/issues/2138

Unrelated to coreaudio, but just to keep the link: https://gitlab.com/qemu-project/qemu/-/issues/2606

just as a data point, the issue this ticket was about has been supposedly fixed by upstream commit

https://gitlab.com/philmd/qemu/-/commit/2ef938a0994097969aab947aeb49982572640687

not sure where that commit is in the releases etc and if we have updated to a version with that commit in it and can therefore close this ticket.

The newly-reported issue with qemu not working on Darwin PPC would appear to be a completely different kind of problem (and one which I doubt would ever be fixed by upstream barring someone providing them with a simple, tolerable, and tested patch).
