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