384 If you think configure made a mistake, make sure you are using the latest
385 version from Git. If the latest version fails, report the problem to the
386 ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
388 if disabled logging; then
390 Rerun configure with logging enabled (do not use --disable-logging), and
391 include the log this produces with your report.
