Question

Just trying out Go, but I can’t get it to compile my very first program. This caused a bunch of questions on the compiler.

It is contained in this single file:

"D:\programming\Go\src\mytest\mytest.go"

the program text is:

// mytest project mytest.go
package mytest

import "fmt"

func main() {
    fmt.Println("Hello, Go!")
}

In the package folder I tried the following commands:

>go build

says nothing. According to go help build this is the intended result.

>go build -v
_/D_/programming/Go/src/mytest

What are the _/D_/ things are??? Looks like a new invention!

And the most strange one:

>go build -v mytest
can't load package: package mytest: import "mytest": cannot find package

So what am I doing wrong and how do I get the thing compiled?

Answer 1

The main function in a program must be in package main. Package main can then import other packages and call them.
