Trying to emerge newest 0.21 ebuild (media-tv/mythtv-0.21_p17100), I get linker errors related to Xvmc if the opengl-xvmc USE flag is specified. Reproducible: Always Steps to Reproduce: 1.add "media-tv/mythtv" to /etc/portage/package.keywords (it's marked as ~ right now) 2.add "media-tv/mythtv opengl-xvmc" to /etc/portage/package.use 3.emerge media-tv/mythtv Actual Results: The compile goes fine until it starts to compile mythfrontend app. Then, it fails with the following results: ... ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCCreateContext' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCCompositeSubpicture' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCFlushSurface' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCHideSurface' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCClearSubpicture' ../../libs/libavcodec/libmythavcodec-0.21.so: undefined reference to `XvMCLoadQMatrix' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCCreateSurface' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCDestroyContext' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCDestroyMacroBlocks' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCGetSurfaceStatus' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCSetSubpicturePalette' ../../libs/libavcodec/libmythavcodec-0.21.so: undefined reference to `XvMCSyncSurface' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCBlendSubpicture' ../../libs/libavcodec/libmythavcodec-0.21.so: undefined reference to `XvMCBeginSurface' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCRenderSurface' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCPutSurface' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCCreateBlocks' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCFlushSubpicture' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCCreateMacroBlocks' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCSyncSubpicture' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCBlendSubpicture2' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCDestroySubpicture' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCCreateSubpicture' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCDestroySurface' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCPutSlice2' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCSetAttribute' ../../libs/libmythtv/libmythtv-0.21.so: undefined reference to `XvMCDestroyBlocks' collect2: ld returned 1 exit status make[2]: *** [mythfrontend] Error 1 make[2]: Leaving directory `/var/tmp/portage/media-tv/mythtv-0.21_p17100/work/mythtv-0.21/programs/mythfrontend' make[1]: *** [sub-mythfrontend] Error 2 make[1]: Leaving directory `/var/tmp/portage/media-tv/mythtv-0.21_p17100/work/mythtv-0.21/programs' make: *** [sub-programs] Error 2 * * ERROR: media-tv/mythtv-0.21_p17100 failed. * Call stack: * ebuild.sh, line 49: Called src_compile * environment, line 3086: Called die * The specific snippet of code: * emake || die "emake failed"; * The die message: * emake failed * * If you need support, post the topmost build error, and the call stack if relevant. * A complete build log is located at '/var/tmp/portage/media-tv/mythtv-0.21_p17100/temp/build.log'. * The ebuild environment file is located at '/var/tmp/portage/media-tv/mythtv-0.21_p17100/temp/environment'. * Expected Results: It should emerge fine.

And what version of nvidia-drivers are you using?
I'm currently using x11-drivers/nvidia-drivers-169.12 both in x86 and x86_64 (I've had this issue in 2 different machines, one with a Pentium 4 3.2 MHz running Gentoo 32 bits, and another one with an Athlon XP running Gentoo 64 bits. Also I don't know if it's relevant or not, but I previously used 'eselect xvmc' to choose nVidia xvmc prior to emerging mythtv. Regards Eduard
What you are seeing is MythTV using the --xvmc-vld (VIA Epia) option as enabled by default. I believe this bug is a dupe of Bug #220587 with the difference in that bug being the user actually having the VIA XvMC libs present on his system, just for a different VIA hardware set other than VIA-vld. Doug, I know you mentioned previously that upstream's instructions were to disable 'xvmcw', but enabling it seems to fix this problem. I have tested using 'xvmcw' and not only did it successfully compile, I am also able to toggle between Xorg's and Nvidia's XvMC at runtime using 'eselect-xvmc', works great. Also looking at MythTV's configure script, if you discount the fact that --xvmc-vld is enabled by default, it actually gives precedence to 'xvmcw' over all other options except for Xorg's libXvMC.so.
Err...that should be a dupe of Bug #220857 not Bug #220587 :|
Any update on this? I entered the bug two weeks ago and it doesn't seem to be any updates since then on MythTV packages. Could you please give any clue about if this is considered really a bug, will be solved, left as is, etc...? Regards Eduard
After discussing this further with upstream, the Ubuntu packagers, and the Fedora packagers, this option is going away in future MythTV ebuilds. As I've mentioned in other bugs, OpenGL XvMC is not something you guys should want. It's mostly slower and has artifacts. It's known to be buggy and broken. Upstream will not be working on it since it requires features that NVIDIA implemented as extensions in their drivers but have since abandoned (support stays as long as it's does not break on compiles). It works only on a select few cards and it actually is only faster on an even smaller handful (do you guys have Quatro cards for you MythTV machines). As such, the flag is going away.
Ok, thanks. Best regards, Eduard
