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