It does it here: if it finds brew on the path, then it’s HB; otherwise, if it finds port on the path, then it’s MP; otherwise, no distribution found. (HP, MP are obviously ‘package managers’, but fitted better into Alire as ‘distributions’).
Yeah, Ada_Switches is mine, it’s not something alr creates.
How are you using Draw and Fill??
Looking at this link now. Most of what I’m trying to do is to automate the specified changes rather than to manually make the changes. I follow (in general) what’s going on now.

Made slight progress. This is really frustrating. It’s almost like doing the Piñata thing but with a twist that the Piñata keeps randomly moving.
I think I’ll go on to something else until this matures a bit more.

I really don’t know what the problem is and you could be waiting a long time before the -gnat2022 switch becomes the default.

I don’t think that my inability to follow the instructions provided is a fault of insufficient maturity of the Ada compiler. I’m also not the one that is not fully mature (I’m way over-ripe!). I really don’t think that the instructions are sufficiently clear in order to obtain a functional SDL-ADA infrastructure that will suffice for the Rosetta Code tasks that already are written in Ada and use SDL.
Please show me the steps that you would do to make any of the Rosetta Code tasks, that are written in Ada, that use SDL, on a Mac with arm, without modification of the Rosetta Code task code. If you needed to modify any of the SDL_ADA infrastructure code in order to do that, then update the documentation accordingly.
Thanks,
RBE

Apologies if I offended anyone. I was (and still am) quite frustrated with this, so I’ll just let it go, it is not worth getting this frustrated and it is not worth insulting people who are vastly smarter than I.

Just try the 3 steps I showed. I don’t know anything about rosetta code and I don’t have a mac.
My version (very little different from @Lucretia ’s):
$ alr init --bin archimedean_spiral
(accept all the defaults)
$ alr with sdlada --use=https://github.com/ada-game-framework/sdlada.git
Go into src/ and replace archimedean_spiral.adb with the one from Rosetta Code.
alr build -- -gnat2022
and end with the same errors @Ret_Build_Engineer noted above.
The fixes for the errors are:
(1) add with SDL.Video.Rectangles; to the context clauses
(2) replace
Renderer.Draw
(Point => (X => Width / 2 + SDL.C.int (R * Cos (T, 2.0 * Pi)),
Y => Height / 2 - SDL.C.int (R * Sin (T, 2.0 * Pi))));
by
Renderer.Draw
(Point =>
SDL.Video.Rectangles.Point'
(X => Width / 2 + SDL.C.int (R * Cos (T, 2.0 * Pi)),
Y => Height / 2 - SDL.C.int (R * Sin (T, 2.0 * Pi))));
(3) replace
Renderer.Fill (Rectangle => (0, 0, Width, Height));
by
Renderer.Fill
(Rectangle => SDL.Video.Rectangles.Rectangle'(0, 0, Width, Height));
The problem was that Renderer.Draw and Renderer.Fill both have overlays, with the different overlays distinguished by the type of the parameter; so we have to tell the compiler which one we mean by using qualified expressions (ARM 4.7).

Enable_Screen renames Enable_Video; -- Deprecated.
could be replaced with:
Enable_Screen : Init_Flags renames Enable_Video; -- Deprecated.
or else adding
Pragma Ada_2022;
to the top of the file.
Or as I point out above, put -gnat2022 flag in your gpr file, it’s a 2022 lib.
— as I said above. This could be in your alire.toml or in sdlada’s alire.toml (but I seem to remember that there were issues when some units were in Ada2022 and some not?).
If it has to be in a GPR, shouldn’t it be in sdlada’s?
The [build-switches] version above ends up in config/archimedean_spiral.gpr.

It is in SDLAda’s gpr file, it’s used to compile the cached sdlada, but not when using the packages from SDLAda.
I intend to look into setting up a starter template project next year, but don’t know how to work that into alire, so will need advice from @AJ-Ianozi.
Hi Simon;
It works. Thanks for your help.
The only thing I need to do to satisfy myself regarding this specific problem is convert the process of the hand-editing of the Ada source as you have shown into a patch process so that the entire build process cvan be completely encapsulated in the bash script driver. I still am working out a self-inflicted bug with my patch creation and usage which I will resolve myself.
I will try (soon) to look at the other Rosetta Code tasks that were written in Ada using SDL and see if I can leverage what knowledge I have gained here to in order to have success locally reproducing them.
Thanks again,
RBE
Indeed, I did alr -v build and there it was – but not when compiling archimedean_spiral.adb.
In this case you don’t need to: I’ve updated the Rosetta Code page.

Simon;
Thank you.
There is one VERY SMALL issue that might be of interest for those who are using MacPorts and Alire:
There is a benign failure when calling port (MacPort command) looking for make, which does not exist as a port, at the end of the “alr with” command:
Error: Port make not found
Is this due to a problem with my PATH environment variable? Why is it looking for make from MacPorts?
Anyway, the build process continues successfully to the end.
Thanks so much for your assistance/guidance.
