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.
```d
import std.stdio : writeln;
void main() {
writeln("Hello, world!");
}
```
Compilation using LDC on macOS is just:
```
ldc2 --release --O3 main.d
```
Or some more options, to reduce executable size:
```
ldc2 --release --O3 --flto=full -fvisibility=hidden
-defaultlib=phobos2-ldc-lto,druntime-ldc-lto -L=-dead_strip -L=-x
-L=-S -L=-lz main.d
```
Executable size using first command: 1.3MB
Executable size using second command: 756KB
