..(belatedly). I have the attached scripts: "m.zip" unpacks to "m.tar" which contains..eg:..which I would have expected to have yielded "__arm__"/"__aarch64__" which begs the question - does something need to be added? On x86 I get..To save the casual reader unpacking, it's merely....replacing 'gcc' with 'g++' accordingly.
