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