187 If you think configure made a mistake, make sure you are using the latest
188 version from SVN. If the latest version fails, report the problem to the
189 ffmpeg-devel@mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net.
191 if enabled logging; then
193 Include the log file "$logfile" produced by configure as this will help
198 Rerun configure with logging enabled (do not use --log=no), and include the
