Summary

How to run .wasmer binary with go? I tried wasmer.DeserializeModule() and it fails with incompatible binary: The provided bytes are not wasmer-universal.

Additional details

I want to embed a package distributed on wasmer.io and I noticed it's not just well-known wasm binary after tried running the binary with another wasm runtime. It's works with wasmer run but I could not run with go.

Reproduction

  1. Donwload binary from https://wasmer.io/syrusakbary/cowsay/releases
  2. See how waasmer run works: wasmer run cowsay-v0.3.0.wasmer hello
  3. It fails with incompatible binary: The provided bytes are not wasmer-universal
package main

import (
	"fmt"
	"os"

	"github.com/wasmerio/wasmer-go/wasmer"
)

func main() {
	wasmBytes, err := os.ReadFile("cowsay-v0.3.0.wasmer")
	if err != nil {
		fmt.Println(err)
		return
	}

	engine := wasmer.NewEngine()
	store := wasmer.NewStore(engine)

	module, err := wasmer.DeserializeModule(store, wasmBytes)
	if err != nil {
		fmt.Println(err)
		return
	}

	_ = module
}
