273 WARNINGS="${WARNINGS}WARNING: $*\n"
280 If you think configure made a mistake, make sure you are using the latest
281 version from Git. If the latest version fails, report the problem to the
282 ffmpeg-user@mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net.
284 if disabled logging; then
286 Rerun configure with logging enabled (do not use --disable-logging), and
287 include the log this produces with your report.
291 Include the log file "$logfile" produced by configure as this will help
