How can I find my package?

Question

Where should I put my package so that it can be imported by another package?

$ tree . ├── main.go └── src └── test.go 1 directory, 2 files $ cat src/test.go package test $ cat main.go package main import "test" $ go build main.go main.go:3:8: import "test": cannot find package 

Answer 1

Install GOPATH. Put your foo source (s) package in GOPATH / src / optional-whatever / foo / *. And use it in code like

 import "optional-whatever/foo" 

You do not need to explicitly install foo, the go tool is a build tool, it will do this automatically if necessary.

Answer 2

There are a few things that must happen. First you need to install the "test" package:

 $ export GOPATH=$(pwd) # Assumes a bourne shell (not csh) $ mkdir src/test $ mv src/test.go src/test/test.go $ mkdir pkg # go install will put packages here $ go install test # build the package and put it in $GOPATH/pkg $ go build main.go 

Note that there is no need to create pkg, as go install will do it for you. After you installed the test package (usually a bad name, BTW) go build main.go , different errors should now appear (for example, "imported and not used")

Answer 3

maybe you can put the test.go file in the same directory as main.go, and in test.go, it uses something like this:

 import "./test"
