[I messed up the freebsd-emulation email address the first time I sent
this. I also forgot to indicate the qemu-user-static vintage =
relationship.]
I had been reporting intermittent hang-ups for my amd64->{aarch64,armv7} =
port cross
builds in another message sequence. But it turns out that one thing I =
ran into
has hung-up every time, the same way, for amd64->armv7 cross builds:
multimedia/gstreamer1-qt@qt5 . So I extract the material here into a =
separate report
with some updated notes.
A little context: I had built from ports head -r484783 before under =
FreeBSD head
-r340287 (as I remember the version). Back then it did not have this =
problem that it
now has under FreeBSD head -r341836 . One ports-specific change was to =
force perl5.28
as the default instead of perl5.26 originally. In fact this is what =
drives what is
being rebuilt for my experiment that caught this. But I doubt the perl =
version is
important to the problem. The context has a Ryzen Threadripper 1950X and =
has been
tested both for FreeBSD under Hyper-V and for the same media =
native-booted. Both
hang-up at the same point as seen via ps or top. The native tools for =
cross-build
speedup were in use. Cross-builds targeting aarch64 did not get this =
problem but
targeting armv7 did. 121 of 129 armv7 ports built before the hang-up for =
the first
armv7 try.
ADDED: The qemu-user-static back with head -r340287 before installing =
the
updated ports would likely be different than the -r484783 vintage. So =
both
FreeBSD and qemu-user-static may have changed over the comparison.
The hang-up:
In the port rebuilds targeting armv7, multimedia/gstreamer1-qt@qt5 =
hung-up and timed
out. Looking during the wait in later tries shows something much like =
(from one of the
examples):

or as top showed it:

So: waiting in kqread trying to run cmake.
Unlike some intermittent hang-ups, attaching-then-detaching via gdb does =
not
resume the hung-up processes. Kills of the processes waiting on kqread =
stop
the build.
Given the prior ports have been built already, building just
multimedia/gstreamer1-qt@qt5 still gets the hang-up at the same point.
Building anything that requires multimedia/gstreamer1-qt@qt5 seems to be
solidly blocked in my environment.
