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