I've been trying to use Cygwin to build ffmpeg but I'm running into the error ./configure: line 1132: cmp: command not found. I tried looking around online for solutions but found none. I also checked if I just didn't download the right package when I downloaded Cygwin but I found nothing relating to cmd. I'm not sure if there is a workaround or not. The code from line 1132 is:
cp_if_changed(){
cmp -s "$1" "$2" && echo "$2 is unchanged" && return
mkdir -p "$(dirname $2)"
$cp_f "$1" "$2"
}
Thanks
You want to install the cygwin diffutils package.
