By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

Description Darrell 2012-12-23 18:30:20 CST 
tdeedu/kstars/configure.in.in checks for videodev.h and videodev2.h. Newer versions of video4linux do not contain videodev.h.

The videodev.h is renamed/relocated to /usr/include/libv4l1-videodev.h.

tdeedu/kstars/configure.in.in needs to be updated to search for both the old file name/location and the new name/location.

The configure warnings:

checking for struct v4l2_buffer... no
checking for /lib/modules/3.2.29/build/include/linux/videodev2.h... yes
configure: WARNING:
configure: WARNING:
configure: WARNING: We cannot locate videodev2.h in /usr/include/linux
configure: WARNING:

configure: WARNING: It is recommended that you copy this file and videodev.h to /usr/include/linux

This should be fixed in GIT hash ab9a2a8 (tdeedu).  The real problem was that videodev2.h was not being detected when the older videodev.h file was not present on the system.

Please test and close this bug if the fix works for you.

Thanks for reporting!

The tdeedu package built with the patch. I don't see the same configure WARNINGs, but how do I know the package built correcty? I don't see any related messages in the configuration output.

Also I did not receive an email after your post. Is the email server working correctly?

Never mind on the mail server. Problem was at my end.

Look for a line referencing v4l2_buffer in the configure output; as long as that line says "yes" then the patch worked.

Tagging as resolved. Thanks!
