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