In order to emerge media-video/ffmpeg2theora ffmpeg needed to be rebuilt with the vhook USE flag enabled: emerge -pv ffmpeg2theora emerge: there are no ebuilds built with USE flags to satisfy "<media-video/ffmpeg-9999[vhook]". !!! One of the following packages is required to complete your request: - media-video/ffmpeg-0.5-r1 (Change USE: +vhook) (dependency required by "media-video/ffmpeg2theora-0.23-r1" [ebuild]) (dependency required by "ffmpeg2theora" [argument]) With vhook USE flag added: emerge -pv ffmpeg2theora [ebuild R ] media-video/ffmpeg-0.5-r1 USE="3dnow 3dnowext X alsa amr encode gsm hardcoded-tables ipv6 jpeg2k mmx mmxext mp3 network sdl speex ssse3 theora threads v4l v4l2 vhook* vorbis x264 xvid zlib (-altivec) -bindist -custom-cflags -debug -dirac -doc -faac -faad -ieee1394 -oss -schroedinger -test" [ebuild N ] media-video/ffmpeg2theora-0.23-r1 But ffmpeg compile fails, producing following diagnostic: libavcodec/eatqi.c:166: internal compiler error: Segmentation fault This is not due to the added vhook USE flag as ffmpeg also fails to rebuild without it. This was with gcc 4.3.3 (gcc (Gentoo 4.3.3-r1 p1.1, pie-10.1.5) 4.3.3). If I switch back to gcc 4.3.2 (gcc (Gentoo 4.3.2-r2 p1.4, pie-10.1.3) 4.3.2) then ffmpeg rebuilds successfully and ffmpeg2theora can be rebuilt with gcc 4.3.3-r1. Reproducible: Always Steps to Reproduce: 1.Emerge ffmpeg with gcc-4.3.3-r1 2. 3. Actual Results: Emerge fails.
