[Qemu-devel] [Bug 1030104] Re: Parallel build doesn't work after "make clean"

[Thomas Huth]

I think this should have been fixed at one point in time - at least it
seems to work for me, so I'm closing this ticket now. If you still have
problems, feel free to open this ticket again, but then please specify
the exact version of QEMU which causes the trouble for you.

Title:
  Parallel build doesn't work after "make clean"

Status in QEMU:
  Fix Released

Bug description:
  After running "make clean" qemu won't build with -j option.
  When I run "./configure && make clean" and then make -j5, following errors 
occur:
    GEN   config-host.h
    GEN   trace.h
    GEN   qemu-options.def
    GEN   qmp-commands.h
    GEN   qapi-types.h
    GEN   qapi-visit.h
    GEN   tests/test-qapi-types.h
    GEN   tests/test-qapi-visit.h
    GEN   tests/test-qmp-commands.h
    GEN   qapi-generated/qga-qapi-types.h
    GEN   qapi-generated/qga-qapi-visit.h
    GEN   qapi-generated/qga-qmp-commands.h
    CC    osdep.o
    CC    qemu-thread-posix.o
  cc1: error: qapi-generated: No such file or directory [-Werror]
  cc1: all warnings being treated as errors

  make: *** [qemu-thread-posix.o] Error 1
  make: *** Waiting for unfinished jobs....
  cc1: error: qapi-generated: No such file or directory [-Werror]
  cc1: all warnings being treated as errors

  make: *** [osdep.o] Error 1

  If you run "make -j5" once again after this, build continues
  succesfully because  "qapi-generated" directory already exists.
