I am trying to install gnu toolchain for compiling Cortex-A code on my MAC os version 10.14. I don't know where to start, can some one please guide me? I see binaries are only available for windows and linux platforms. I downloaded source from developer.arm.com/.../downloads and tried to build but built gcc does not take -march=arm64v8a option.
You have to install the aarch64 tool chain not arm tool chain. But I see not MacOS binaries, so ...
Also: arm64v8a is no valid option.
