Package request: Rust and Cargo

[hinmatth]

As the popularity of Rust grows, Rust support in Termux would be extremely helpful to both Rust experts and beginners.

The binaries and libraries of Rust and Cargo are also shown to be compilable and buildable in ARM despite the fact that they should be compiled in Rust instead of C. Hence, building Rust and Cargo packages for Termux would seem highly feasible. A link towards the corresponding Github repo is provided below.

Thanks.

I was about to request this. I also would love to see rust added to the collection. In fact, termux with a full compiler collection is becoming a very valuable tool.

Good news for cross-compilation of Rust and Cargo on termux :)

Rustup doesn't work on termux (which is not a termux bug, just pointing out that rustup is not a solution)

$ curl -sSf https://static.rust-lang.org/rustup.sh | sh
rustup: gpg available. signatures will be verified
rustup: unknown CPU type: aarch64

@andreiw, sure, but using rustup on a pc os, you can easily compile the rust compiler for arm architectures i presume 😄

The link is pointing to the wrong place in the OP comment

Same with this one

Has anyone tested if rustup is working for ARM7 cpus? @andreiw seemed to try it on ARM64

Getting a permission denied error on rustup.sh in termux, chmod a+x doesn't help

[insunaa]

Rust isn't a bad match. It's also using the LLVM backend, which should already be installed since Termux comes with the clang toolchain.

This happens when I run the latest rustup.sh

Edit the script and insert the correct shell path in the shebang. I think it's /system/bin/sh under android (although please check).

Trying a different approach which is still relevant to the topic:

Downloaded rustup-init (the arm7 build), copied it to /data/local, switched to su and chmod +x rustup-init, then tried to run it. I now get a different error but I think this may be more relevant.

shamu:/data/local # sh rustup-init
rustup-init: line 1: syntax error: unexpected word (expecting ")")

Edit: used this build rustup-init

[gheoan]

I get the same error as @wrsg.

The rustup-init tool isn't available to android, yet. The only way to get rust on android will be through cross compiling it. I have tried it but I am not that familiar with their build system.

@vishalbiswas The next version of rust is switching to a new build system that requires Python, so it may be wise to wait until that version before doing any serious packaging.
