Jbuilder hello_world example error

I stumbled upon the same problem. Could you please link to the issue you submitted?

EDIT I found two issues related to the hello_world project, both still open (Jan 2018):

• Example (hello_world) fails to build · Issue #283 · ocaml/dune · GitHub
  hello_world: "No rule found for alias ..." · Issue #240 · ocaml/dune · GitHub

The second issue, #240, is the one I opened, fwiw.
