make check produces ERROR (GLib-ERROR **: 17:50:29.132) when installing QEMU Emulator on OSX

Question

Got below ERROR when installing QEMU Emulator on OSX (following the steps in the bottom lines of https://pdos.csail.mit.edu/6.828/2018/tools.html):

ERROR: (tests/test-string-output-visitor:4303): GLib-ERROR **: 17:50:29.132: duplicate test case path: /string-visitor/output/int
make: *** [check-tests/test-string-output-visitor] Error 1

What does this ERROR mean? How to fix?

Answer 1

This looks like an error with (older) QEMU in combination with a newer GLib. See https://patchwork.ozlabs.org/patch/526287/.

The patch suggested in the link above:
