354 If you think configure made a mistake, make sure you are using the latest
355 version from Git. If the latest version fails, report the problem to the
356 libav-tools@libav.org mailing list or IRC #libav on irc.freenode.net.
358 if disabled logging; then
360 Rerun configure with logging enabled (do not use --disable-logging), and
361 include the log this produces with your report.
