[Octave-bug-tracker] [bug #64836] [MXE] Build falilure of Qt-6.6.0

[Markus Mützel]

Follow-up Comment #1, bug #64836 (project octave):

It's working for me locally and in the CI.

The actual error is probably a bit earlier in the log file:

Which distribution are you on? Are the pthread development packages installed
on your system?
