Hi people! I am on a gentoo machine, after updating my kernel, linux header and restarted my machine I wanted to compile "media_build". What could this be ?! That I get this error ?

http://pastebin.com/raw.php?i=Ubt5qhP0

output:

/storage/downloads/media_build/v4l/videobuf2-core.c:29:30: fatal error: trace/events/vb2.h: No such file or directory #include <trace/events/vb2.h> ^ compilation terminated. scripts/Makefile.build:264: die Regel für Ziel „/storage/downloads/media_build/v4l/videobuf2-core.o“ scheiterte make[3]: *** [/storage/downloads/media_build/v4l/videobuf2-core.o] Fehler 1 Makefile:1386: recipe for target '_module_/storage/downloads/media_build/v4l' failed make[2]: *** [_module_/storage/downloads/media_build/v4l] Error 2 make[2]: Leaving directory '/usr/src/linux-4.2.3-gentoo' Makefile:51: recipe for target 'default' failed make[1]: *** [default] Error 2 make[1]: Leaving directory '/storage/downloads/media_build/v4l' Makefile:26: recipe for target 'all' failed make: *** [all] Error 2 build failed at ./build line 491.
