Need native ARM64 Linux toolchain

[pmunts]

to run on 64-bit Raspberry Pi OS (which is based on arm64 Debian 12). ARM64 Linux computers are becoming mainstream; I even saw an ARM64 Chromebook at Best Buy on Black Friday.

Hello @pmunts, it's on our TODO list :)

In the meantime, I am pretty sure Debian will provide a GNAT package that you can use.

Me too!

I currently use gnat, gprbuild, and alire from Debian for arm64 development. However, I build gnatprove, gnatcov, ada_language_server, gnattest, etc. myself for arm64. So +1 to this request! Thanks!

[dalybrown]

@pmunts we internally build our own ARM64 linux toolchain for Ada (including all those tools I mentioned above and more). It's not in our public repository at the moment but we would be more than happy to make it public to share. Ideally it would be hosted with their amd64 counterparts.

If you let me know what tools you want first I can prioritize moving those builds to our public repository or just send them to you.

@dalybrown Making your ARM64 toolchain public would be great! Whenever I try to build them myself, mainly gnatcov, I always seem to end up with 20 dependencies that don't all fit together very well.

How soon do you need it all? I'm swamped over the next few weeks but early spring I can move all our toolchains builds to GitHub. I planned to do that already anyways at some point.

I noticed a bit of work on arm64 tooling ... but it seems mostly for Apple Silicon.

Is it still the plan to have all the tooling available for linux arm64 @mosteo ? I'm currently building everything I mentioned above and it's a pain to maintain!

Hi @dalybrown, I'm not involved in the work on particular compiler architectures. I guess @Fabien-Chouteau will know better.

Right on. I'll let him reply and go from there.

I see that the work on the ARM64 tooling is mostly for Apple Silicon. Are there any plans to make this tooling available for Linux ARM64? Maintaining all the builds is proving to be a challenge. I am curious to know if there are any plans or updates on this front. Thank you. Get Outlook for iOS<https://aka.ms/o0ukef>

Hi,

I noticed a bit of work on arm64 tooling ... but it seems mostly for Apple Silicon.

Because GitHub now provides Actions runners for Apple arm64 platforms. Which is not the case for other OSes, so we are limited in what we can do here.

Ok!

Does GitHub allow you to run docker on the Apple arm64 runners? If so, it would be straightforward to build the tools. I'm happy to contribute to that (I already build all the tools for linux arm64 using qemu + docker on amd64 machines and then just docker on my Mac M1).
