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