303 WARNINGS="${WARNINGS}WARNING: $*\n"
310 If you think configure made a mistake, make sure you are using the latest
311 version from Git. If the latest version fails, report the problem to the
312 ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
314 if disabled logging; then
316 Rerun configure with logging enabled (do not use --disable-logging), and
317 include the log this produces with your report.
321 Include the log file "$logfile" produced by configure as this will help
328 # Avoid locale weirdness, besides we really just want to translate ASCII.
