[vlc-devel] V4L2 Compiling on Gentoo

[Richard Hosking]

Sorry for the delay.

I went back and removed types.h.  Attached is the output from
make.  You can see the videodev2.h file failing to compile
before the v4l2.c file.

This compiles fine under Ubuntu 7.04 (kernel 2.6.20), but I
am getting the failure with Gentoo 2007.1 (kernel 2.6.22).

I am using an identical ./configure and build sequence on
Gentoo as under Ubuntu.

../configure --prefix=/usr --enable-debug --enable-dbus-control --enable-shared-libvlc \
--with-ffmpeg-tree=../extras/ffmpeg --enable-x264 --with-x264-tree=../extras/x264 \
--enable-v4l --enable-v4l2 --enable-dvb --disable-xvmc --enable-svg \
--enable-theora --enable-twolame --enable-flac --enable-tremor \
--with-ffmpeg-mp3lame --with-ffmpeg-faac --enable-esd \
--disable-portaudio --disable-cddax --disable-vcdx \
--disable-quicktime --disable-dc1394 --enable-png --disable-qt4 \
--disable-skins2 --disable-libcddb --disable-wxwidgets --enable-alsa \
--enable-screen --with-live555-tree=../extras/live

(a headless streaming server)

Best Regards,
Richard.
