在OSX上安装QEMU Emulator时，make check产生错误(GLib-ERROR **：17:50:29.132)

Question

在OSX上安装QEMU Emulator时出现以下错误(按照https://pdos.csail.mit.edu/6.828/2018/tools.html最下面几行中的步骤操作)：

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

这个错误是什么意思？如何修复？

Answer 1

这看起来像是(较旧的) QEMU与较新的GLib组合出现的错误。参见https://patchwork.ozlabs.org/patch/526287/。
