331 If you think configure made a mistake, make sure you are using the latest
332 version from Git. If the latest version fails, report the problem to the
333 libav-tools@libav.org mailing list or IRC #libav on irc.freenode.net.
335 if disabled logging; then
337 Rerun configure with logging enabled (do not use --disable-logging), and
338 include the log this produces with your report.
342 Include the log file "$logfile" produced by configure as this will help
