338 If you think configure made a mistake, make sure you are using the latest
339 version from Git. If the latest version fails, report the problem to the
340 ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
342 if disabled logging; then
344 Rerun configure with logging enabled (do not use --disable-logging), and
345 include the log this produces with your report.
349 Include the log file "$logfile" produced by configure as this will help
