The problem solved on changeset https://trac.pjsip.org/repos/changeset/3888 seens to occur again on osx 10.8 version. The fix on changeset listed below handle only with 10.7 version and not 10.8(Mountain Lion). I think that after 10.7 version the framework will always be AudioUnit. + # OS X Lion support + if platform.mac_ver()[0].startswith("10.7"): + extra_link_args += ["-framework", "AudioUnit"] Att, -- Vitor Esp?ndola -------------- next part -------------- An HTML attachment was scrubbed...
