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