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