If the latest version fails, report the problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "ffbuild/config.log" produced by configure as this will help solve the problem. make: *** [/home/buildroot/buildroot-test/instance-1/output/build/ffmpeg-3.4.5/.stamp_configured] Error 1 make: Leaving directory `/home/buildroot/buildroot-test/instance-1/buildroot'
