    11I think that the error message is very misleading. First, it says that arm-none-eabi-gdb was being installed for X86-64 (I never intended that). Secondly, it states that the reason for failing is that the dependency arm-none-eabi-gcc has been installed for arm64; however, the real reason is that arm-none-eabi-gdb does not support building for arm64, because it is not listed as a supported architecture by the crossdb portgroup.

    3 Anyway, I don't understand why arm-none-eabi-gdb cannot be built for arm64. In my case, I intend to use this port for cross-debugging programs running on a BBC micro:bit microcontroller board connected to my Mac via USB, and using PyOCD for communication with the onboard debugger. These programs are being cross-compiled, cross-assembled and cross-linked using arm-none-eabi-gcc and arm-none-eabi-binutils. The executbale so generated is converted using objdump from ELF to bin formats. The architecture of the host computer (the Mac) is completely irrelevant for all this to work. In fact, I installed the complete toolchain (including arm-none-eabi-gdb) using Homebrew and it works perfectly.
