Golang包括本地文件

Question

I have the following two files:

a.go:

package main

func foo() {
    return 42
}

b.go:

package main

func main() {
    println(foo())
}

From what I've learned, it seems as if two files in the same package (and the same directory) should be able to use each other's functions. Yet, when I run go run b.go, I get the following:

# command-line-arguments
./b.go:4: undefined: foo

What's up? Do I have to somehow import a.go in my b.go?

Answer 1

You need to run using the two files go run a.go b.go
