Question regarding GNAT availability for MacOS arm64 via getada (or not) with the new ALIRE release

Help

I just updated to the MacOS arm64 version of Alire 2-3.

First of all: Thank you for providing a MacOS arm64 version!

Now my question. I tried to use a pre-existing failing attempt to solve a Rosetta Code task (Hamming numbers) using the new release of Alire.

Changes to dependency solution:

   +   gnatcoll_gmp 26.0.0 (new)
   +📦 libgmp       6.3.0  (new,indirect,system package)

   🛈  The solution requires a toolchain that is
      not yet installed. Accepting the solution
      will download and install this toolchain.

Do you want to proceed?
[Y] Yes  [N] No  (default is Yes) n
```


Would this have downloaded an x86-64 version of GNAT Ada compiler? or would it fail? or would it actually find an arm64 MacOS GNAT Ada?

I'm on MacOS 26.5 (Tahoe) arm64.

Thanks,
RBE

Hi RBE,

I may be wrong here, but I believe the warning is about libgmp, which is a external package. Alire can detect external GNAT installations and if not, it should ask you to install one (via Alire) or configure one manually. So short answer, I think Alire should be able to detect your toolchain and would not install a new one.

Best regards,
Fer
