Framebuffer problem

[fucai1116]

Hi,
Recently I put some printf into the module/video_output/fb.c to see how VLC use framebuffer. But VLC didn't use it, and had no any video output. Below is my config:

./configure --prefix=/usr --enable-debug \
--disable-alsa \
--disable-a52 \
--disable-bonjour \
--disable-cdda \
--disable-cmml \
--disable-daap \
--disable-dts \
--disable-dvdnav \
--with-dvbpsi-tree=../libdvbpsi4-0.1.5 \
--enable-faad --with-faad-tree=../faad2-2.0 \
--enable-fb \
--with-ffmpeg-tree=../ffmpeg-export-2007-05-23 \
--disable-freetype \
--disable-fribidi \
--disable-glx \
--disable-gnomevfs \
--disable-growl \
--disable-gnutls \
--disable-libcdio \
--disable-libcddb \
--disable-libxml2 \
--disable-libtar \
--disable-libmpeg2 \
--disable-mkv \
--disable-mod \
--disable-mpc \
--disable-mad \
--disable-nls \
--disable-notify \
--enable-oss \
--disable-opengl \
--disable-ogg \
--disable-png \
--disable-sdl \
--disable-sdl-image \
--disable-smb \
--disable-skins2 \
--disable-speex \
--disable-vcd \
--disable-visual \
--disable-vorbis \
--disable-wxwidgets \
--disable-xinerama \
--disable-x11 \
--disable-x264

What was wrong here? Or did I misunderstand something else? Can anyone show me?

Thanks in advance,
T.
