• Product: Gentoo Linux

[Description Paul Giordano 2003-02-19 06:36:55 UTC]

emerge media-libs/gst-plugins-0.6.0-r2 fails, looks like videodev2.h is not at
the correct level - installled with sys-kernel/linux-headers-2.4.20. 


Reproducible: Always
Steps to Reproduce:
1. emerge gst-plugins
2.
3.

Expected Results:  
clean compile

picked up the patches in http://bytesex.org/patches/2.4, updated the header with
those. That cleared it up.

which patches did you need exactly ?

[Comment 2 foser (RETIRED) 2003-02-19 15:10:54 UTC]

disabling v4l for now.. since header fixing might take some time. question still stands

[Comment 3 Paul Giordano 2003-02-26 22:01:09 UTC]

linux-2.4.20/include/linux/videodev2.h out of 11-v4l2-api-2.4.20.diff.gz is where the enumerators are.

this had been reported and fixed in GStreamer CVS:

http://bugzilla.gnome.org/show_bug.cgi?id=105467

patching the linux-headers is not a good idea since it'll break for people running 2.4.19. although how many are still running this, i don't know.

[Comment 5 foser (RETIRED) 2003-04-03 08:09:01 UTC]

v4l is disabled in current gst-plugins ebuilds, we'll just re-enable when the fix is in a release.
