I think

  ocamlc -pp camlp4o -c mysource.ml

should be sufficient. In some cases you might need to load additional
Camlp4 modules, in which case you'd do something like:

  ocamlc -pp 'camlp4o foo.cmo' -c mysource.ml

E.g., a commonly-used set for when you write your own syntax extensions is:

  ocamlc -pp 'camlp4o pa_extend.cmo q_MLast.cmo' -c mysource.ml

[ Pa_extend parses the grammar extension syntax, and Q_MLast processes
  quotation expanders to generate an AST. ]

But that's not what you're doing, so try the simplest version first.
