What did you do?

I have a go file and want to compile it into a wasm file.

package main
import (
	"fmt"
)

func main() {}

//export Greet
func Greet() {
	fmt.Println("this is greet test")
}

First, I compile it into a greet.wasm using the go command :

GOOS=wasip1 GOARCH=wasm go build -o greet.wasm greet.go

And then, using tinygo to compile into greet2.wasm

tinygo build -target wasi -o greet2.wasm greet.go

Run the function Greet of greet.wasm and greet2.wasm using the iwasm tool provided by wasm-micro-runtime

What did you see happen?

The greet2.wasm was run successfully, but the greet.wasm was run failed, and display a error: lookup function failed

What did you expect to see?

The iwasm tool of wasm-micro-runtime can run the function from wasm which compiled by go

GOOS=wasip1 GOARCH=wasm only supported after go 1.21.0.linux/amd64 and not GOOS=js
