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