[kvm-unit-tests PATCH v2 2/4] Makefile: Prepare for clang EFI builds

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



clang complains about GNU extensions such as variable sized types not
being at the end of structs unless -Wno-gnu is used. We may
eventually want -Wno-gnu, but for now let's just handle the warnings
as they come. Add -Wno-gnu-variable-sized-type-not-at-end to avoid
the warning issued for the initrd_dev_path struct.
