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 the wasm-bindgen command with wasm-pack build
