It's already supported.

how to set PKG_CONFIG_SYSROOT_DIR?

It's already supported.
I don’t know how to change the settings. For Android, I will set the cc and sysroot to compile successfully. How to set this wasm packaging environment? I use wasm-pack build to package or the prompt is not found <stdio.h> I think it should be cc and sysroot settings The problem

You need to use emscripten target, which provides stdio.h and alike.

rustup target add wasm32-unknown-emscripten
# install emscripten and set up env for emcc, and then
cargo build --target wasm32-unknown-emscripten --lib

Great.

Do you have the glue js for the wasm project? I found that the wasm file packaged in the project is difficult to use

[kornelski]

No, I don't. You'll have to use the public interface in Rust, and then export (perhaps with wasm-bindgen) your own entry point.

[wangbang79408854]

wasm-bindge is use wasm32-unknown-unknown? but gifski is only use wasm32-unknown-emscripten

[kornelski]

Ooof, indeed. You'll need to manually write the wrapper using #[no_mangle] extern fn. I haven't done it this way, so I can't recommend specifics.

I have given up using wasm, on the server，How to start multithreading, currently only two CPUs are used

If anyone stumbles upon this issue via a search engine or llm, I've hacked together a wasm port with an easy JavaScript interface that should be easy to get started with – https://github.com/jamsinclair/gifski-wasm.
