go build works fine but go run fails

I have a few files in the main package under one directory:

main.go config.go server.go

When I do: "go build" the program builds perfect and runs fine. When I do: "go run main.go" it fails.

Output:

# command-line-arguments
./main.go:7: undefined: Config
./main.go:8: undefined: Server

The symbols that are undefined are structs and they are capitalised so should be exported.

My Go version: go1.1.2 linux/amd64

Solution 1:

This should work

go run main.go config.go server.go

Go run takes a file or files and it complies those and only those files which explains the missing symbols in the original post.

Solution 2:

You could execute it as:

go run .

so you don't have to include all files manually.
