importing one ml file into another

Question

I have an interpreter.ml file that contains an interpreter and some type definitions.

I've developed some test batteries to check if the interpreter works well or not.

When I put the functions I use to test the behaviour of the interpreter in the same file of the interpreter all works well, but if I try to use a different file for the tests (let's say tests.ml ) it did not load the interpreter functions and definitions.

the interpreter.ml and tests.ml are in the same folder

I tried both with open Interpreter and #use "./interpreter.ml" from inside tests.ml but it wont compile nor shut down the warnings in the IDE (kind of...I'm using Visual Studio Code on MacOs )

I've already tried to follow the official documentation but it won't compile with ocamlopt -c tests.ml

Answer 1

As a result of discussions, the executable is obtained by compiling the 2 files test.ml & interpreter.ml in the right order ( test.ml relies on objects defined in interpreter.ml ; as a consequence test.ml has to reference to interpreter objects either via the clause open Interpreter or by prefixing all relevant items with Interpreter ):

  ocamlc -o exec interpreter.ml test.ml 

ocamlbuild is easier as it resolves by itself the dependencies: The following command:

  ocamlbuild test.native 

will produce the executable.
