1) In order to compile your module, you need to tell ocamlbuild you are using the simplemem plugin. You can use: $ ocamlbuild -use-ocamlfind -pkgs cil,cil.simplemem foo.cma foo.cmxs Note that if your command-line invocation grows too much, you can write a _tags file to drive ocamlbuild (you'll still need the -use-ocamlfind flag though): $ cat _tags <foo.*>: package(cil), package(cil.simplemem) Of course, you are not limited to Simplemem, or even to CIL plugins: this technique works to link any OCaml library installed with ocamlfind. 2) To use your plugin, you also need to load cil.simplemem. You can either use: $ cilly -load cil.simplemem -load foo.cmxs or, if you install your plugin with ocamlfind, add the following line to your META file: requires = "cil.simplemem" Note that order matters if you use the command-line option. The advantage of the META file is that ocamlfind figures out the right dependency order for you (and it's more concise of course). Let me know if this solves your issue. I'll try and update the gist at some point with your example.
