Go + Go Lang 在另一个文件中调用函数

Question

目录布局:

~ cd $GOPATH
~ tree src/simple 
src/simple
└── main
    ├── main.go
    └── other.go

main.go:

package main

import "fmt"

func main() {
    fmt.Println("This is in main. calling somefunc...")
    somefunc()
    fmt.Println("done. bye :)")
}

其他.go:

package main

import "fmt"

func somefunc() {
    fmt.Println("This is in somefunc in other.go")
}

这适用于 go build:

~ cd $GOPATH/src/simple/main/
~ go build
~ ./main
This is in main. calling somefunc...
This is in somefunc in other.go
done. bye :)

在 GoLand IDE 中，如果我运行，我会得到:

main/main.go:7:2: undefined: somefunc

通常，编辑器会突出显示所有语法错误。 somefunc 调用在编辑器中被视为有效语法，但当我运行时它不起作用。我什至可以通过 cmd-click 进入函数以跳转到定义。

这是 GoLand 2018.2.3 和 go version go1.11

Answer 1

在GoLand中创建一个运行配置Run -> Edit Configurations基于Go Build模板并设置

Name: Build (or whatever you like)Run kind: DirectoryDirectory: /Users/gopher/go/src/simple/main/                                      ^^^^^^Run after build: checkedWorking directory: /Users/gopher/go/src/simple

相应地更改 /Users/gopher/go/ 部分，以匹配 $GOPATH 的实际路径

然后Run -> Build 项目

This is in main. calling somefunc...This is in somefunc in other.godone. bye :)Process finished with exit code 0
