如何用Go语言编译程序？

Question

I'm walking the first steps with Go language and I'm trying to install it in Debian Squeeze. I follow the step of downloading the source code and then, I did this on my terminal:

cd $GOROOT/src
./all.bash

At the end, it says this:

# Checking API compatibility.
Go version is "go1.1.1", ignoring -next /root/go/api/next.txt
~pkg net, func ListenUnixgram(string, *UnixAddr) (*UDPConn, error)
~pkg syscall (darwin-386), func Fchflags(string, int) error
~pkg syscall (darwin-386-cgo), func Fchflags(string, int) error
~pkg syscall (darwin-amd64), func Fchflags(string, int) error
~pkg syscall (darwin-amd64-cgo), func Fchflags(string, int) error
~pkg syscall (freebsd-386), func Fchflags(string, int) error
~pkg syscall (freebsd-amd64), func Fchflags(string, int) error
~pkg text/template/parse, type DotNode bool
~pkg text/template/parse, type Node interface { Copy, String, Type }

    ALL TESTS PASSED

---
Installed Go for linux/amd64 in /root/go
Installed commands in /root/go/bin

So, the book says that I need to do some tests and compile it with 6g. But I try it this way:

Compile this first Go-program with: 6g test.go This compiles to a file: test.6 which is linked with the command: 6l test.6 This produces the executable named: 6.out which executes with the command: ./6.out and produces the output: Hello, world

But nothing works, my code is:

package main
func main() {
         println(“Hello”, “world”)
}

So, I do not know what more to do... I do know now the name of my compiler, so I have no idea how to compile this in Debian... If you please, give a hand with this... I would be really thankfully to you!

It looks like you are following instructions from:

The Way to Go: A Thorough Introduction to the Go Programming Language By Ivo Balbaert. Section 2.3 Installing Go on a Linux system

These instructions are out of date. They use an obsolete release of Go, release 0.60. You have installed Go release 1.1.1.

For up-to-date instructions see Installing Go from source

Also, when you copy programs from the book, the book uses “ (left double quotation mark) and ” (right double quotation mark) in the code examples. Go expects " (quotation mark).

Write the test.go Go program as:

package main

func main() {
    println("Hello", "world")
}

When you installed Go, it told you it "Installed commands in /root/go/bin." You need to have /root/go/bin in your $PATH so that it can find (recognize) the Go commands.

From the directory which contains the test.go file, run

$ export PATH=$PATH:/root/go/bin
$ go version
go version go1.1.1 linux/amd64
$ go run test.go
Hello world

If this fails, what output do you get?
