Package request: Crystal

[ravener]

It would be nice to have the crystal programming language compiler on Termux, it uses LLVM and is also self-hosted/bootstrapped but since Rust is on Termux while its also self-hosted it should also be possible, via cross-compilation and stuff.

Some hardcoded prefix paths would also need to be patched.
See also This PR for ideas of more patches that might be needed.

I second the request

I'm trying to build Crystal myself on termux, but I can't get all the required dependencies.

Okay, but maybe someone would have an idea if you would

1. document the steps
2. what's currently missing

[Mhowser]

I followed the instructions here https://github.com/crystal-lang/crystal/wiki/All-required-libraries#general

When I got to sudo make install, I had to do ./configure --prefix=/data/data/com.termux/files/usr/bin and then do make install which worked.

I failed at getting the dependencies here https://github.com/crystal-lang/crystal/wiki/All-required-libraries#ubuntu

if you want to get the thing done, using alpinelinux from proot-distro run

apk add crystal shards musl-dev

musl-dev is the culprit that solves all the missing .so file errors

A while ago I managed to get it working (Crystal could even build itself on Termux), but I forgot the exact list of dependencies: https://forum.crystal-lang.org/t/running-crystal-on-termux/3880

Heads up: Crystal's master branch now has support for AArch64 Android (via --target=aarch64-linux-android), but not LLVM 15+ nor API levels 24 - 27 yet
