qemu @4.2.0: Undefined symbols: _clock_gettime

Reported by: ryandesign (Ryan Schmidt) Owned by: raimue (Rainer Müller)
Priority: Normal Milestone:
Component: ports Version: 2.6.2
Keywords: legacy-os haspatch Cc: franckbonin
Port: qemu

Description

Even though the qemu port includes the legacysupport portgroup, it fails to build on Lion with an error that including that portgroup should have corrected:

  LINK    qemu-nbd
Undefined symbols for architecture x86_64:
  "_clock_gettime", referenced from:
      _read_f in qemu-io-cmds.o
      _readv_f in qemu-io-cmds.o
      _write_f in qemu-io-cmds.o
      _writev_f in qemu-io-cmds.o
      _aio_read_f in qemu-io-cmds.o
      _aio_read_done in qemu-io-cmds.o
      _aio_write_f in qemu-io-cmds.o
      ...
ld: symbol(s) not found for architecture x86_64

Since the problem happens at link time, it makes me wonder if the build system might not be respecting our LDFLAGS. I can't see, because the build system uses silent rules.

As this only affects outdated versions of macOS, I will not work on the issue myself. However, if anyone else can come up with patches, I will happily them.

Could you at least modify the build to disable silent rules, so that we can investigate further?

i fixed this already before. And then ionic took that fix and tweaked it. did this come back again?

qemu does not use link args normally. there's a lot of analysis in the previous ticket where we fixed this.

Previously, it looks like the port was building correctly in the build phase, and then rebuilding incorrectly in the destroot phase. The fix was to prevent the incorrect rebuild.

Now, in #60494, we see that the problem still exists in 5.0.0 and that it fails during the initial build. It seems to just be ignoring our LDFLAGS entirely.
