mkdir: created directory 'build' /MagicMind/ffmpeg-mlu/ffmpeg/ffmpeg-4.4/build /MagicMind/ffmpeg-mlu/ffmpeg/ffmpeg-4.4 /MagicMind/ffmpeg-mlu/ffmpeg /MagicMind/ffmpeg-mlu gcc is unable to create an executable file. If gcc is a cross-compiler, use the --enable-cross-compile option. Only do this if you know what cross compiling means. C compiler test failed. If you think configure made a mistake, make sure you are using the latest version from Git.  If the latest version fails, report the problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.libera.chat. Include the log file "ffbuild/config.log" produced by configure as this will help solve the problem.
