How to use struct from another package?

[Shrimpy Wu]

get "unknown TryGo.TestStruct field 'a' in struct literal" error. why i cannot use struct from another package?

in my source code i have below folder/files structure, and i run command "go run main/main.go"

src

  |--main

  |     |---main.go

  |

  |

  |----MyType.go

main.go

package main

import (

  "fmt"

  "github.com/shrimpy/TryGo"

)

func main()  {

  testStructInst := TryGo.TestStruct {

    a: "a",

    b: "b",

    c: "c",

  }

  fmt.Println(testStructInst)

}

in MyType.go

package TryGo

type TestStruct struct {

  a string

  b string

  c string

}

You can use the struct, you just can't use field "a", because it's lowercase and thus "package private" :)

You need to first "go get" your own package from github because of the way you import it. If you don't want to do that, put MyType.go inside its own folder (src/TryGo/) and get rid of github.com/shrimpy/ from the import path.

ksug also has a good point. If your package import path is "foo/bar/pkgname", your package should be in "$GOPATH/src/foo/bar/pkgname" (no matter if github is involved or not).
