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