I see stuff for handling aach64/arm64, so it SHOULD work, but there are things I don't understand about AARCH64 to figure it all out. Still, it should be detected. Out of curiosity, if you do a "make -C /usr/ports/devel/llvm10 config", the line for BE_NATIVE should show the architecture you are running on. If it's missing/something else, maybe you should ask brooks@ about it. -- Kevin Oberman, Part time kid herder and retired Network Engineer E-mail: rkoberman@gmail.com PGP Fingerprint: D03FB98AFA78E3B78C1694B318AB39EF1B055683
