#46709: Failed to configure ffmpeg ------------------------+---------------------- Reporter: wangsix@… | Owner: devans@… Type: defect | Status: assigned Priority: Normal | Milestone: Component: ports | Version: Resolution: | Keywords: Port: ffmpeg | ------------------------+---------------------- Comment (by devans@…): Per the log, error this time is {{{ :info:configure ERROR: libass not found using pkg-config }}} So you may need to do the same with it. However, this all looks like something is definitely not right with your ports installation. These errors are saying the the ports in question are installed but not all expected files are available (.pc files for instance). If you continue to run into this sort of problem, you may need to remove MacPorts completely and reinstall to make sure you have a consistent installation. Have you recently upgraded your OS from another version? If so did you follow the [https://trac.macports.org/wiki/Migration Migration] instructions? -- Ticket URL: <https://trac.macports.org/ticket/46709#comment:6> MacPorts <https://www.macports.org/> Ports system for OS X
