ARMv6 support

[NelsonBrandao]

Hi, Is there any plan to support armv6?

This project would be a good replacement for converting SVG to PNG without puppeteer on the Raspberry pi zero

Raspberry Pi Zero is too old, you can try to compile it yourself using zig cc.

I was able to cargo install resvg the main lib on the Pi Zero. That is why I created this issue, to see if we could get official support.

Will try to compile resvg-js on the Pi Zero

you can install that because Rust supports the specified architecture. It's not because resvg has done something special about it. Besides, this project is not an official resvg affiliated project. We currently distribute to some chosen platforms using pre-compiled packages, adding more packages will make it harder to maintain. So I think manually compile it is a better choice now. Don't hesitate to ask if there's any difficulties doing so.

I was trying to setup this repo on my Pi but yarn install can't install @swc/core. Not sure if this is another problem related with ARMv6, this time on swc side.

If you're just building binary .node files, you don't need to install any other dependencies, just @napi-rs/cli and then npm run build.

> napi build --platform --release --js js-binding.js --dts js-binding.d.ts

    Finished release [optimized] target(s) in 0.12s

So I ran rustc -vV on the Pi Zero to get the correct target:

rustc 1.69.0 (84c898d65 2023-04-16)
binary: rustc
commit-hash: 84c898d65adf2f39a5a98507f1fe0ce10a2b8dbc
commit-date: 2023-04-16
host: arm-unknown-linux-gnueabihf
release: 1.69.0
LLVM version: 15.0.7

Decided to trigger the build on the actual Pi Zero instead of trying to cross compile. This was done by running npm run build -- --target arm-unknown-linux-gnueabihf

The build didn't throw any errors:

{...}
Finished release [optimized] target(s) in 109m 08s

and a resvgjs.linux-arm-gnueabihf.node file was created.

I then replace the original node_modules/@resvg/resvg-js-linux-arm-gnueabihf/resvgjs.linux-arm-gnueabihf.node inside my project node_modules with my built version.

Unfortunately the node script still throws an error when executing

Illegal instruction

I'm I doing something wrong here?

Btw thanks guys for all the help so far, much appreciated.

Sorry, but since the Raspberry Pi Zero is so old, I'm not going to support it and close this issue for now. If you figure out how to build it, feel free to share it here.
