I use packs, but so far I was pretty certain that this used the compiler to find the location in .opam; some of the packages that I use with PACKS are not dependencies of the local library and are installed through opam. PACKS finds them, and to be clear, I do in fact have multiple installations of some libraries, and at different versions between the local development and opam.

Hi,

Ok. Does anybody know how to use OCamlMakefile to have it do this? The
commands already call ocamlfind before ocamlc;

ocamlfind ocamlc ...

To use OCaml packages with OCamlMakefile, you want...

PACKS = mylib anotherlib yetanotherlib

Here's an example OCamlMakefile-based makefile:

See the OCamlMakefile documentation for the rest of the options.
