= note: the wasm32-unknown-unknown target may not be installed
can this be fixed ??

[aboutqx]

btw, cargo install command seems changes. cargo install -f wsam-bindgen-cli --version 0.2.29 works.

[chinedufn]

Thanks! 1a3bd0a

[aboutqx]

Would you please share some information about running this on windows?
Just new to rust, can't figure out why building on win fails.

[chinedufn]

Oh sorry I thought you had it working.

What error are you seeing?

[chinedufn]

Oh whoops now I see - run this:

rustup target add wasm32-unknown-unknown

Does that work?

[aboutqx]

It helps，the before errors disappear，get some grammar error.

my rust version is rustc 1.41.0 (5e1a79984 2020-01-27)
It seems that nalgebra package doesn't work.
What about upgrading the nalgebra package version?

[aboutqx]

dimforge/nalgebra#616
The new version fixed this.
How can i get it all upgraded?
blender-armature = "0.2.0" blender-mesh = "0.4.6" still use the old nalgebra.

[chinedufn]

Want to try adding nalgebra as a patch dependency to the tutorial's `Cargo.toml1? Does that work?

Something like:

[patch.crates-io]
nalgebra = "=0.16.3"

https://doc.rust-lang.org/edition-guide/rust-2018/cargo-and-crates-io/replacing-dependencies-with-patch.html

[aboutqx]

try [patch.crates-io] nalgebra = { path = "C:/Users/Administrator/.cargo/registry/src/mirrors.ustc.edu.cn-61ef6e0cd06fb9b8/nalgebra-0.19.0" }
Compile completes.
Still get errors.

I try to comment the build.rs main function.
It outputs

Looks like the mesh function from bytes have some problems there.

[chinedufn]

Gotcha - you just have to change your Cargo.toml to match the repository since the tutorial was written against older versions https://github.com/chinedufn/webgl-water-tutorial/blob/master/Cargo.toml#L13-L14

[aboutqx]

Still got some other grammer errors. Maybe I need to learn more rust first.

[chinedufn]

You can just delete that line

[chinedufn]

I've updated the instructions and the build script to work again fd1e209 .

If you follow the latest instructions in the README everything should work for you.

Let me know if there's an issue! Thanks for surfacing this!

[aboutqx]

Thanks a lot. It finnally got working.
Be glad to see more tutorials about webgl + rust.

[chinedufn]

You got it!
I wrote a Rust + WebGL physically based rendering tutorial that I'll be publishing in April - take a peek at the blog around then.
