I have issues with some gstreamer plugins when I compile them with hardened gcc. Changing the gcc-config to vanilla specs gcc and recompiling the problematic plugin fixes the problem. The problems that I encountered were with: gst-plugins-alsa, gst-plugins-xvideo. I probably haven't tested many other plugins though. This was discussed already in bug: #70631 and solutions were suggested by the hardened herd... another plugin has a problem: goom, which is part of the gst-plugins package. After going through with a user on irc, I found the following: plugins that are fully self contained work fine in hardened plugins that link to other gst libs (eg alsa) have problems resolving symbols even though ldd shows that the relevant libs are linked If this is indeed taken care of in the next gstreamer branch, maybe it is possible in the meanwhile to have the ebuilds disable hardened and use vanilla specs for the broken plugins? through a hardened USE flag... I've suffered exactly the same symptoms as specified in Bug 81512. Having ensured that I've removed and re-prelinked without the /usr/lib/gstreamer directory, I can only assume it's because I've got hardened enabled now. The error message states that the registry is broken (but a recreation of the registry doesn't help) or that the /usr/lib/gstreamer/libgst<blah> isn't there (which upon checking it always is). Hopefully this is the right place to locate the exact problem and perhaps get a patch upstream. I'm happy to test out as many different experimental builds as people can produce and return any debugging results that may be required to try and fix this. I've included my emerge info in case it's of any use. I hope we can get this fixed soon...

Because the problem can show in a very indirect way. Ok, well, it's been a while, and I've just seen version 0.8.10 plugins come and go, and I was wondering what was happening with this bug? It appears it still has yet to be fixed upstream in the branch, and I was wondering if anyone here has the know-how/expertise to figure out what's causing it to go wrong? Most noticably I haven't been able to find an official gstreamer bug for it, so could someone please point me to it, or if it doesn't exist could someone from the gstreamer herd please report it to them? Also, since another version has gone by and it's still affecting people (most noticably the gnome volume applet breaks badly) is there any chance that the ebuild could be modified to drop back to the vanilla specs, or simply filter out the offending flags if that's all it is? Any help to get this thing solved would be appreciated. Thanks very much, Mike 5:) I just built gstreamer and gst-plugins, 0.8.10, and I can confirm that using the hardened gcc profile (even with CFLAGS="" LDFLAGS="" as suggested in the forums) I could not get a working "adder". Then I did this: gcc-config -f powerpc-unknown-linux-gnu-3.4.4-vanilla && emerge -v --oneshot gstreamer gst-plugins && gcc-config -f powerpc-unknown-linux-gnu-3.4.4 (Rebuilt the other plugins also, while troubleshooting amarok.) I have now confirmed that gstreamer will work; it will even produce sound. Stale dead bug. |
