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