253 If you think configure made a mistake, make sure you are using the latest
254 version from SVN. If the latest version fails, report the problem to the
255 ffmpeg-user@mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net.
257 if disabled logging; then
259 Rerun configure with logging enabled (do not use --disable-logging), and
260 include the log this produces with your report.
264 Include the log file "$logfile" produced by configure as this will help
271 # Avoid locale weirdness, besides we really just want to translate ASCII.
