[Qemu-devel] [Bug 1623020] [NEW] emulate amd64 binary on arm7 host

[Bilal Amarni]

Public bug reported:

I'm trying to run a Go program compiled for amd64 on a Raspberry Pi.
Here is an example :

===
// main.go
package main

func main() {
        println("hello world")
}
===

Then here is the output I'm getting :

===
