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