What did you do?

Write a simple program then go build then put it in another os.

package main

import (
	"fmt"
	"net/http"
)

func main() {
	http.HandleFunc("/", handler)
	http.ListenAndServe(":8080", nil)
}

func handler(w http.ResponseWriter, r *http.Request) {
	fmt.Fprint(w, "11")
}

runs

➜  fuck git:(master) ✗ go build -o fuck_linux_amd64
➜  fuck git:(master) ✗ ldd fuck_linux_amd64
        linux-vdso.so.1 (0x00007ffd921ee000)
        libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f4ab861d000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f4ab842b000)
        /home/linuxbrew/.linuxbrew/lib/ld.so => /lib64/ld-linux-x86-64.so.2 (0x00007f4ab864a000)

scp it to a CentOS 7 server produces

-bash: ./fuck_linux_amd64: /home/linuxbrew/.linuxbrew/lib/ld.so: bad ELF interpreter: no such file or directory

What did you expect to see?

can run the program

What did you see instead?

By default Go programs that import the "net" package, in your example via "net/http", are dynamically linked with the system libraries and system dynamic interpreter. That can in some cases mean that those programs can't be run on a different system. That is what is happening to you.

You can avoid this by setting CGO_ENABLED=0 when you run go build. That will give you a statically linked program. That has various consequences, such as not supporting certain complex and unusual DNS configurations.

I'm closing this issue because this is not a bug in Go. If you have further questions about this, please do not use the issue tracker. Please use a forum instead. See https://golang.org/wiki/Questions. Thanks.
