Re: [Xen-devel] [PATCH 3/3] stubdom: fix -Wextra usage in vtpm_emulator



Olaf Hering, le Tue 22 Jul 2014 09:19:17 +0200, a écrit :
> If -Wextra is appended to CFLAGS it will enable all warnings. Previous

> appearently remember -Wno-* options before -Wextra.
> Rearrange warning options for gcc so that -Wextra comes before other -W
> options. This fixes compilation of stubdom in SLES11.
