How can I see how dune is invoking the ocaml compiler?

I'd like to reproduce some of dune's functionality in buck2, but have no idea how to implement dune's functionality where a wrapped module can specify a library interface.

I'd like to see how dune is invoking ocaml tools such as ocamlopt.opt, to see what flags are passed. In buck2 this can be done with buck2 what-ran, does dune have something similar?

If not, where can I stick a Printf.printf in the dune source to see how it's invoking other tools?

Solution

  • You may be looking for the --display option with a value of verbose.

    dune exec --display=verbose
