xcode – How to compile FFmpeg for arm64e – clang is unable to create an executable file

I have met the same issue, and after checked, I found the parameter “–cpu” is incorrect for arm64. The original is “–cpu=arm64-v8a”. The correct one is “–cpu=armv8-a”. The “–cpu” parameter must be start with “armv”, you can find the clue in the FFMPEG configure file like below:

case $cpu in
    armv*)
        cpuflags="-march=$cpu"
        subarch=$(echo $cpu | sed 's/[^a-z0-9]//g')
    ;;
    *)
        cpuflags="-mcpu=$cpu"
        case $cpu in
            cortex-a*)                               subarch=armv7a  ;;
            cortex-r*)                               subarch=armv7r  ;;
            cortex-m*)                 enable thumb; subarch=armv7m  ;;
            arm11*)                                  subarch=armv6   ;;
            arm[79]*e*|arm9[24]6*|arm96*|arm102[26]) subarch=armv5te ;;
            armv4*|arm7*|arm9[24]*)                  subarch=armv4   ;;
            *)                             subarch=$(probe_arm_arch) ;;
        esac
    ;;
esac
