Let say you are having a project with src/ sub directory and two .go files inside: hello.go and typetest.go and both defines the same package "main". One of them (hello.go) also implements func main().

To make it compile as whole you need to make sure two things are configured properly: GOPATH and Run/Debug configuration.

Open the Project Libraries/GOPATH settings:

For Gogland

File -> Settings -> Go

For Intellij IDEA

File -> Settings -> Languages & Frameworks -> Go -> Go Libraries

Makes sure the GOPATH for the project looks something like that:

Next, open Run -> Edit Configurations and make sure your configuration looks similar to this:
