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