Wasm compilation failing

[josediegorobles]

I have this problems (and are the same problems with this an other libraries like rgb-node since month ago):

It finnally comes that is rustc-serialize that is deprecated in favour of serde but is being used by grin_secp256k1zkp.

I see this issue of yours:

#9

How is the issue going, there are plans to substitute one for another, it's possible to contribute to that?

Thanks

The issue depends on secp256k1-zkp and nobody is working on it. I am out of professional capacity of doing this cryptography stuff :( I had even proposed grants; but all cryptographers who is able to implement lack not money but time.

Thanks! It's much clearer for me now the situation.

Hi @dr-orlovsky,

After update to v0.10, I tried compiling with wasm-pack build and occurs this error:

After investigate, I noticed this configuration in syn library:

We need change all parse() to parse2() in amplify_syn lib.

Also, I made some changes in Cargo.toml to work with wasm-pack:

[package]
name = "rgb-core"
version = "0.10.0-beta.1"
authors = ["Dr Maxim Orlovsky <[email protected]>"]
(...)
[lib]
name = "rgb"
crate-type = ["cdylib", "rlib"] # <--- HERE
(...)
[target.'cfg(target_arch = "wasm32")'.dependencies]
getrandom = { version = "0.2", features = ["js"] }  # <--- HERE

I hope this help.

@crisdut thank you for all the details and investigation of the fix. I have applied it here: rust-amplify/amplify-derive#36

I will do a new release now - and update RGB Core dependency version, adding WASM CI. Let's see would it solve the issue
