Toolchain with ldc and AArch64 OSX

[Cecil Ward via Digitalmars-d-learn]

I have LDC running on an ARM Mac. If anyone else out there is an 
LDC or GDC user, could you knock up a quick shell program to 
compile and link a .d file to produce an executable ? found the 
linker but these tools are all new to me and a bit of help would 
save me a lot of trial and error and frustration as I try to find 
docs. GDC would be great too.

I have managed to achieve this before on a Raspberry Pi AArch64 
Linux Debian where the compiler can link and generate an 
executable just in integrated fashion in the one command. The OSX 
tools seem rather different however.

I’m going to try installing GDC on the Mac next, have got that 
running on the Pi too successfully.
