Hello: I contacted upstream about it earlier and was about to open a bug report.
The library currently is versioned by upsteam as 0.0.0 but upstream broke the ABI without bumping the SONAME. I sent a patch upstream to bump the SONAME but I have not heard from him yet but it has only been hours. I'm trying to see if upstream will bump the soname to 1 or re-add the removed symbols. I could bump the SONAME to 0debian1 if I don't get a reply from upstream soon. I'm already preparing a package and checking if all the reverse dependencies build. I already checked dolphin-emu and and a rebuild fixes it. So the transition should be easy. For a SONAME bump I would also need someone to upload it to experimental since it would require a trip via NEW. Two trips if we go 0 -> 0debian1 -> 1. Cheers, Miguel
