fontconfig not found using pkg-config 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.freenode.net. Include the log file "ffbuild/config.log" produced by configure as this will help solve the problem. package/pkg-generic.mk:220: recipe for target '/home/buildroot/build/instance-0/output/build/ffmpeg-3.4.5/.stamp_configured' failed make: *** [/home/buildroot/build/instance-0/output/build/ffmpeg-3.4.5/.stamp_configured] Error 1 make: Leaving directory '/home/buildroot/build/instance-0/buildroot'
