ghcup-hs VS termux-packages

I'd recommend using ghcup to install Haskell nowadays. (https://www.haskell.org/ghcup/) It makes it easy to install and switch versions of the compiler, language server, and build tools.

The compiler now shows more helpful error messages and GHCup allows us to manage multiple versions of GHC, Stack, and HLS (Haskell Language Server) in a breeze. Compilation time is faster now, but I believe it is because hardware has become faster over the years. Unfortunately, cross-compiling is not yet as simple.

Install Haskell using GHCup. In days of old installing Haskell used to be a pain, but nowadays Haskell comes with a self-isolated thing call ghcup - you install it once, and then it installs the rest of the universe in its own isolated directory that can be independently deleted or updated without affecting the rest of your system.

Try this https://www.haskell.org/ghcup/ but with Window's WSL2.

I've downloaded GHCup, hls and stack from the command from this link https://www.haskell.org/ghcup/

The instructions to install ghcup are here: https://www.haskell.org/ghcup/

I have been using helix with ghcup installed ghc(s) and language servers. It works with Haskell out of box, no configuration necessary. Helix is a modal editor, similar to but distinctly different from the vi family. Although a long time vim user I have found the switch to helix not too difficult and definitely worth the trouble.

What method were you thinking of using? The recommended method is ghcup

Yes. Even without enabling root, you can install Termux[1] and have a full Linux cli environment with ssh.

I agree. I sync my camera folder with Syncthing[1], so as soon as I take a photo it is available on my laptop.

As usual don't forget that Android/Linux isn't GNU/Linux,

With this, I was able to cross compile lone for x86_64 from within the Termux environment of my aarch64 smartphone. All I had to do was obtain the Linux user space API headers for x86_64.

I made a Termux package request for multiplatform Linux UAPI headers specifically so I could cross compile lone but unfortunately it was rejected.

I wonder how far you could get with the git client in termux. I got vim running at one point.

Crystal can be installed with just pkg install crystal. If you have Docker, you could also clone the build environment and try building Crystal locally with scripts/run-docker.sh scripts/build-package.sh -I -a aarch64 crystal.
