Bug 389079 – x11-misc/x11vnc-0.9.{9,12,13} - v4l support broken, fails silently, useless v4l useflag

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Fab 2011-10-31 10:17:37 UTC]

Hi,

On versions 0.9.9 and 0.9.12 (and 0.9.13, and upstream git [1]), the configure script is looking for the old linux/videodev.h header. The v4l useflag is then useless.

configure.ac :
> if test "x$with_v4l" != "xno"; then
>         AC_CHECK_HEADER(linux/videodev.h,
>                 [AC_DEFINE(HAVE_LINUX_VIDEODEV_H)],,)
> fi

When running configure with v4l useflag on, the output is :
> checking linux/videodev.h usability... no
> checking linux/videodev.h presence... no
> checking for linux/videodev.h... no

I know that's an upstream bug, but currently I rebuild my world with the v4l useflag on (wrt bug #385241), and while reading the x11vnc ebuild I was wondering why the ebuild does not depend on media-libs/libv4l nor linux-headers. That's because the v4l support in x11vnc is simply broken.

Maybe the v4l useflag should be temporarily masked for x11-misc/x11vnc until the issue is fixed by upstream.
