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