DMD is x86 only. M1 macs can run x86 via rosetta.

I haven't had this specific problem. Can you list the actual commands 
you are running, and the output from the system?

it's simple as following:

-iMac ~ % curl -fsS https://dlang.org/install.sh | bash -s dmd

 Unsupported Arch arm64


So install.sh is checking the architecture, and failing because the OS 
reports it as arm64.

```sh
case $(uname -m) in
     x86_64|amd64) ARCH=x86_64; MODEL=64;;
     aarch64) ARCH=aarch64; MODEL=64;;
     i*86) ARCH=x86; MODEL=32;;
     *)
         fatal "Unsupported Arch $(uname -m)"
         ;;
```

You could change the line that starts with `aarch64` to `aarch64|arm64`

That might work. I'm not sure, because really you want x86_64 for dmd 
(there is no aarch64 or arm64 build of dmd).

Have you tried using the dmg package?

Is there a reason you want to use DMD specifically?  If you use 
homebrew then `brew install ldc dub` will just works for dub 
projects, and to explicitly run the compiler just use `ldc2` 
instead of `dmd`.  LDC is actually an ARM executable and outputs 
ARM executables.  I assume it's easy to install ldc without 
homebrew, but I haven' tried.

So where is your ssl library located and how (if at all) are you 
telling the compiler/linker where to find it?

I installed openssl and also export the path of lib, but still 
got that errors...

you are right, the package install is OK. but after running dub 
build --compiler=dmd, the error of "ld: library not found for - 
lssl" is still there...

I've not had problems since updating to the M1, but my system was 
upgraded through many years, so I don't know if it's because I just have 
old cruft leftover.

I'd try installing the dev tools from apple, probably you'd get the ssl 
library then?

I've fixed this quite some time ago:
https://github.com/dlang/installer/pull/491

Apparently it was never released?

Get LDC here: https://github.com/ldc-developers/ldc/releases

- If you are running on Apple Silicon, be sure to use the 
Universal LDC package (for LDC version >= 1.30).

- If the "Universal" build is not available, use the x86_64 LDC 
package instead. (for LDC version < 1.30).

Those builds are cross-compilers, able to target both x86_64 and 
arm64, with flags -a x86_64-apple-macos and -a arm64-apple-macos 
respectively.




Make sure you are using the dub and ldc2 executable from those 
builds. Please install Xcode 12.2+ to.

     $ sudo ln -s /my/absolute/path/to/ldc-xxx/bin/ldc2 
/usr/local/bin/ldc2
     $ sudo ln -s /my/absolute/path/to/ldc-xxx/bin/dub 
/usr/local/bin/dub


- build a x86_64 program with: `dub -a x86_64-apple-macos`
- build an arm64 program with: `dub -a arm64-apple-macos`
