将主包放入两个文件中[重复]

Question

This question already has an answer here:

• go build works fine but go run fails 2 answers

In $GOPATH/src/testapp I have two files

• main.go
• otherfile.go

main.go has

package main

import "fmt"

func main() {
  fmt.Println(SomeFunc())
}

otherfile.go has

package main

func SomeFunc() string {
  return "a thing"
}

When I try to run with go run main.go, I get an error

./main.go:6: undefined: SomeFunc

I thought I could create another file with package main and code in main.go would have access to its declarations. Why doesn't this work? How would I do something like this?

Answer 1

If I run go run *.go it works.
It also works if I go build and then ./testapp.
Hopefully this question helps someone in the future.
