Once you install Termux and Debian with proot-distro, you can install anything that is or can be compiled for Arm and can run in Debian. Then installation is just as for a Linux desktop/laptop.

But no juliaup 😢

I don’t use juliaup (as I mention in lwn.net/Articles/100...), but I don’t see why you can’t install it on the phone too.

I don't have an LWN subscription so haven't read your linked article, but I do enjoy how juliaup works. I'm an electrical engineer and I primarily use Julia by way of Pluto notebooks for analysis or simulation.

Try lwn.net/SubscriberLi...

When I said "no juliaup" it's because I had hit this ~ $ curl -fsSL install.julialang.org | sh info: downloading installer curl: (22) The requested URL returned error: 404 juliaup: installer for platform 'aarch64-linux-android' not found, this may be unsupported

Oh, how unfortunate.

Biggest barrier is laziness / time constraints / or that I don't enjoy the puzzles of trying to build something on an unsupported platform.

You don’t have to build Julia. Just download the Arm binary from julialang.org. That’s what I did on my phone.
