188 External library support:
190 Using any of the following switches will allow FFmpeg to link to the
191 corresponding external library. All the components depending on that library
192 will become enabled, if all their other dependencies are met and they are not
193 explicitly disabled. E.g. --enable-libwavpack will enable linking to
194 libwavpack and allow the libwavpack encoder to be built, unless it is
195 specifically disabled with --disable-encoder=libwavpack.
197 Note that only the system libraries are auto-detected. All the other external
198 libraries must be explicitly enabled.
200 Also note that the following help text describes the purpose of the libraries
201 themselves, not all their features will necessarily be usable by FFmpeg.

513 If you think configure made a mistake, make sure you are using the latest
514 version from Git. If the latest version fails, report the problem to the
515 ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
517 if disabled logging; then
519 Rerun configure with logging enabled (do not use --disable-logging), and
520 include the log this produces with your report.
524 Include the log file "$logfile" produced by configure as this will help
