hello world tutorial error

[finetjul]

In the hello world tutorial, a folder named wasi-build is referenced. I personally (on Windows 11 , VSCode, git bash, [email protected]) have only an emscripten-build folder, no wasi-build folder.

❯ npx itk-wasm run wasi-build/hello.wasi.wasm
Hello Wasm world!

It builds into the correct wasi-build folder with [email protected].

You might want to update the tutorial documentation accordingly.

Other problem I had on Windows: in loadEmscriptenModuleNode.js, I had to replace const fullModulePath = `${modulePrefix}.js`; with const fullModulePath = `file://${modulePrefix}.mjs`; and renaming hello.js into hello.mjs in emscripten-build.

First error:

Error [ERR_UNSUPPORTED_ESM_URL_SCHEME]: Only URLs with a scheme in: file, data are supported by the default ESM loader. On Windows, absolute paths must be valid file:// URLs. Received protocol 'c:'

Second error:

(node:25640) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)
C:\Work\wasm\hello_world\emscripten-build\hello.js:3
  var _scriptDir = import.meta.url;
                          ^^^^

SyntaxError: Cannot use 'import.meta' outside a module

Finally, here is the WASI error when trying to run the build:

PS C:\Work\wasm\hello_world> npx itk-wasm run wasi-build/hello.wasi.wasm
ERROR: Unknown option "--args,-e"

Usage: dockcross [options] [--] command [args]

By default, run the given *command* in an dockcross Docker container.

The *options* can be one of:

    --args|-a           Extra args to the *docker run* command
    --image|-i          Docker cross-compiler image to use
    --config|-c         Bash script to source before running this script


Additionally, there are special update commands:

    update-image
    update-script
    update

For update command help use: wasi-build/itk-wasm-build-env help <command>
undefined

@finetjul thanks for the report!

For the first issue, here is a patch: #784

I will attempt to reproduce the others once on a Windows system.
