Programming WebAssembly with Rust: building Rogue WebAssembly game
I’m trying to build the Rogue WebAssembly game from chapter 4, using the code provided on the website.
In build.sh
, the wasm-bindgen
command is failing with the stack-trace at [1] below. My version of wasm-bindgen
is 0.2.67. I have tried changing the Cargo.toml
file to “0.2”, instead of “^0.2”, but the result is the same.
thanks!
Michael
p.s. I am enjoying the book, though it might be better to have the code hosted on GitHub?

With wonderful help from friends [1], here are steps that enabled the jsint_roguewasm
example on my machine:
- edit
index.js
to import from./pkg/roguewasm
instead of./roguewasm
- edit
src/lib.rs
to import from../index
instead of./index
- in
build.sh
, replace thewasm-bindgen
command withwasm-pack build
