Hi all. I've built a native 5.4.0 on a PINE64 SBC. To my surprise, it doesn't understand "-march=native", giving me this error; "error: unknown value ‘native’ for -march" A 5.4.0, built using the same script but on x86_64, understands "native". The GCC which comes with the Debian on the PINE64 also doesn't understand "native". I could be wrong, but I thought "native" invoked special magic in GCC such that it would have a good guess at your native system; if that's correct, then this mechanism seems to be missing. What's up with this? and words of wisdom?
