I’m having a hard time importing a library from do go. The library is in a folder in the same project directory and always of the import error, when not of the import error, of the error to access the function.
main go.
package main
import (
"fmt"
"./test"
)
func main(){
test.makeCalc(1,1)
fmt.Println("test.makeCalc(3,6)")
}
test go.
package test
func makeCalc(x int, y int) int{
return x+y
}

First create the following folder structure:
/path/to/app
|-main.go
|-src
|-test
|-test.go
Make sure that /path/to/app is included in GOPATH.
Otherwise, include it:
$ # em linux
$ cd /path/to/app
$ export GOPATH=$GOPATH:/path/to/app
The code that is in test.go, to be used in main.go, needs to be exported, so use:
package test
func MakeCalc(x int, y int) int{
return x+y
}
I hope I’ve helped!
According to the documentation, GOPATH is the folder where the desktop is. From what I understand, it cannot be composed of multiple paths. To set this variable in the bash use $ export GOPATH=/pasta/para/a/area/de/trabalho. reference: Setting GOPATH
Yes, it can be composed of multiple locations! The difference is that the first location defined will be the location where libraries will be installed by default that will be installed during the preparation phase of the project.

According to the specification, the interpretation of the
importdepends on the compiler implementation. I recommend usingimportwith the canonical name of the package.– Anderson F. Viana
