main.go undefined: target

G'day,

This project looks pretty cool, but seems like it doesn't build, although maybe I'm being silly.

das@das-dell5580:~/go/src/github.com/czerwonk$ rm -rf ping_exporter/
das@das-dell5580:~/go/src/github.com/czerwonk$ git clone https://github.com/czerwonk/ping_exporter.git

Possibly:

• a Makefile would make things more clear how to build this.
• target.go seems to define "target"

This is an easy trap to fall in:

$ go build *.go

or just

$ go build

should get you a ./ping_exporter.
