A user reported on #fedora today, symbol lookup error: /lib64/libavcodec.so.55: undefined symbol: vpx_codec_vp9_dx_algo". vpx_codec_vp9_dx_algo appears to be a new symbol in libvpx-1.3, not included in 1.2. I didnt look closely yet, but if there's this one, there may be others. Seems there may be alright: http://upstream-tracker.org/compat_reports/libvpx/1.2.0_to_current/abi_compat_report.html Options: * Since you're already using a version script, consider versioning these affected symbols (won't help stuff built already, but will benefit anything built against the fixed libvpx) * bump soname or any other better idea you can think of.
AFAIK the version script is used only on our secondary arches, primary arches use the internal buildsystem.
The internal stuff builds with a version script too... so this should all be done. Upstream continues to use the versioning of the release as the soname version, so this didn't bump the major soname. This really ought to be something handled by the upstream, but since they're Google, I don't expect it to happen. Closing this CANTFIX.
