I'm trying to write a basic go program that calls a function on a different file, but a part of the same package. However, it returns:
undefined: NewEmployee Here is the source code:
main.go:
package main func main() { emp := NewEmployee() } employee.go:
package main type Employee struct { name string age int } func NewEmployee() *Employee { p := &Employee{} return p } func PrintEmployee (p *Employee) { return "Hello world!" } Thanks in advance
Please read "How to Write Go Code".
Don't use /src in your GOPATH. Packages are located in $GOPATH/src.
For build or install you need to have your files in a package directory.
For go run, you need to supply all files as argument:
go run main.go employee.go But, you should almost always use go install, or go build (and preferably the former, as go build causes confusion when working with non-main packages)
I just had the same problem in Gogland and worked out that you need to change the "Run Kind:" from File to Package. You can choose this from a drop-down if you go into Run/Edit Configurations...
If your source folder is structured /go/src/blog (assuming the name of your source folder is blog).
That should run all of your files at the same time, instead of you having to list the files manually or "bashing" a method on the command line.
