[Qemu-devel] [Bug 1634726] Re: qemu "make test" fails in iov.c with "undefined reference" on aarch64 on Ubuntu 16.04

[Peter Maydell]

You want 'make check' to run the self-tests. 'make test' is a bunch of
broken old stuff :-(

Title:
  qemu "make test" fails in iov.c with "undefined reference" on aarch64
  on Ubuntu 16.04

Status in QEMU:
  New

Bug description:
  I'm building the master tree on a multicore ARMv8 machine running
  Ubuntu 16.04. The build worked just fine, using the simple directions
  in the README file and "make -j 64" to do the build.

  Next, I did "make test", and got this:

  address@hidden:~/src/qemu/qemu/build$ make test
  make -C tests/tcg test
  make[1]: Entering directory '/mnt/src/qemu/qemu/build/tests/tcg'
    CC      test_path.o
    LINK    test_path
  test_path.o: In function `qemu_iovec_is_zero':
  /home/emv/src/qemu/qemu/util/iov.c:365: undefined reference to 
`buffer_is_zero'
  collect2: error: ld returned 1 exit status
  /home/emv/src/qemu/qemu/rules.mak:105: recipe for target 'test_path' failed
  make[1]: *** [test_path] Error 1
  make[1]: Leaving directory '/mnt/src/qemu/qemu/build/tests/tcg'
  Makefile:498: recipe for target 'test' failed
  make: *** [test] Error 2

  I expected "make test" to complete with no errors.
