Subject: [Qemu-devel] [PATCH] vl: fix build when configured with no graphic support
Date: Tue, 29 Oct 2013 08:36:31 +0400	[thread overview]
Message-ID: <1383021391-3152-1-git-send-email-antonynpavlov@gmail.com> (raw)

The following error occurs when building no graphic output support:

  vl.c: In function ‘main’:
  vl.c:2829:19: error: variable ‘ds’ set but not used [-Werror=unused-but-set-variable]
       DisplayState *ds;
                     ^
  cc1: all warnings being treated as errors

To reproduce this issue, just run:

  $ ./configure \
      --disable-curses \
      --disable-sdl \
      --disable-cocoa \
      --disable-gtk \
      --disable-vnc \
      --enable-werror
  $ make vl.o
