250 If you think configure made a mistake, make sure you are using the latest
251 version from SVN. If the latest version fails, report the problem to the
252 ffmpeg-user@mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net.
254 if disabled logging; then
256 Rerun configure with logging enabled (do not use --disable-logging), and
257 include the log this produces with your report.
261 Include the log file "$logfile" produced by configure as this will help
