I just tried to execute a Hello World from VSCode 1.28.2 (Windows 8.1) in a C:Scriptshello_world.go file:

package main



import (

    "fmt"

)



func main() {

    fmt.Println("Hello, Gopher!")

}

My environment is as follows:

• I installed Go from scratch using the Windows installer:

$ go version

go version go1.11.2 windows/amd64

• Installed on C:Go


• Installed VSCode Go Extension: https://marketplace.visualstudio.com/items?itemName=ms-vscode.Go
  


• Installed debugger:

go get -u github.com/derekparker/delve/cmd/dlv

• Checked with SystemPropertiesAdvanced:
  
  
  
  
  • Local Variable GOPATH = %USERPROFILE%go
  
  
  • Local Variable PATH adds %USERPROFILE%gobin
  
  
  • System Variable PATH adds C:Gobin
  
  
  • System Variable GOROOT = C:Go
  
  
  
  


• I have MinGW64, GitBash and MinGW 1.0 (However I don't see how that could affect running Go from VSCode)


• Running from cmd.exe runs the program without problems at all:

C:Scripts>go run hello_world.go

Hello, Gopher!

In VSCode settings my global go.gopath and go.goroot settings are:

  // Specify GOPATH here to override the one that is set as environment variable. The inferred GOPATH from workspace root overrides this, if go.inferGopath is set to true.

  "go.gopath": null



  // Specifies the GOROOT to use when no environment variable is set.

  "go.goroot": null

So I customized the variables from VSCode as follows:

{

    "editor.renderControlCharacters": false,

    "go.inferGopath": true,

    "go.goroot": "C:\go",

}

Now this is the weird part. When I hit Ctrl+F5 compilation takes a "Example_c.c" file (?) and reports errors with that file (which I never created or even knew that existed):

I already tried deleting all my temporary files and restarted VsCode multiple times. The whole experience to setup a Go environment to debug a hello world is really dissapointing.

What else can I check? Any hints?

Your GOPATH should point to "C:Scripts". Then point the "program" variable in launch.json to "C:Scripts" to run it in Debug Mode.
