# webassembly

One question, I'm trying to run this example, https://github.com/Kotlin/kotlin-wasm-examples/tree/main/wasi-example, with wasmtime, but when I do it like this: wasmtime kotlin-wasm-wasi-example-wasm-wasi.wasm from the /build/compileSync/wasmWasi/main/developmentExecutable/kotlin directory if fails with this message: Error: failed to parse WebAssembly module

Caused by:
Invalid input WebAssembly code at offset 366: rec group usage requires gc proposal to be enabled

[João Esperancinha]

Anyone can help me with this?

Wasmtime has not yet implemented the Wasm GC feature that Kotlin needs: https://github.com/bytecodealliance/wasmtime/issues/5032

Thanks for letting me know about this!

You may try using it with Node.js for now, @João Esperancinha

[edrd]

Since it does support GC

[João Esperancinha]

I'll have a look at that. Thanks!

Oh, I assumed you needed wasmtime in particular.
You can find steps for running Node (and Deno!) in the repo you mentioned. Adding Gradle -i flag would show node and deno cli commands.
