What's the current status of the project?

Is this project currently working? I tried installing and running the example from the README, but the resulting wasm file seems to only include the runtime and does not contain my own OCaml code.

Hi,

Could you tell me which steps did you follow exactly? (local build, or through an opam switch?) Could you also provide the source file and the resulting Wasm?

[Wybxc]

I am using the toolchain installed with opam switch (as per the instructions in the README).

The test file is as follows:

let _ = print_string "!!!!!!\n"
let msg = "Hello WebAssembly!"
let _ = print_string msg
let _ = print_newline ()
let _ = print_string "!!!!!!\n"

OK, so, a few things:

• a module containing only the runtime looks like the flambda option was not enabled properly within the compiler, could you try with the "local build" instructions ?
• printing function are not going to do anything unless a proper "host" runtime is provided, for instance, you can use these files (index.html, main.js) and put the result of compiling fib.ml in a.out.wasm, then running python -m http.server 8000 && xdg-open http://localhost:8000 should run the module properly and display the numbers in the browser console ;
• note that Wasocaml was a prototype made to validate the WasmGC proposal and convince the WG to keep i31 in the design, it is not actively maintained, development might restart if we find someone to fund a proper implementation on flambda2 (oxcaml).

Best,
