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
libav-user@libav.org mailing list or IRC #libav 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
