It looks like the culprit is +vnc, as without this flag the configuration (and the subsequent build) succeeds.

Please remember to fill in the Port field and Cc the maintainer.

My apologies! Honestly forgot. :-(

I'm seeing the same error with +vnc and/or any of the +target_* variants

As the error was thrown by meson, the real error description must be inside the meson log file:

1099	:info:configure A full log can be found at /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_emulators_qemu/qemu/work/build/meson-logs/meson-log.txt

I'm seeing a similar error trying to install qemu 6.2.0 with all variants disabled, on macOS 11.6 with Xcode 12.5.1

@raimue

Would it be possible to get a qemu package with VNC enabled? Thanks for taking a look and let me know if you need more info.

[raimue (Rainer Müller)]

As +vnc is even in the defaults variants now, this does not seem to be a problem any more. Binary archives were built on the buildbot for macOS >= 11.
