ocamlopt, .cmxa and "not a compilation unit description" error Options

Hi,

I'd like to generate a library from a file that uses the nums library
(in a way such that the final user of my library does not have to
specify that nums is necessary).

I was able to generate a .cma with the following command:
ocamlc -a nums.cma file.ml -o lib.cma

However to generate a .cmxa, the command:
ocamlopt -a nums.cmxa file.ml -o lib.cmxa

fails and reports the error that "nums.cmxa is not a compilation unit
description."

I can always do:
ocamlopt -a file.ml -o lib.cmxa

But the user of my library will have to necessarily specify nums.cmxa
when compiling his project.
Is there a way to go around this? (for instance, by putting the option
nums.cmxa into the library?)

Thank you.

Have you considered using ocamlfind?

Don't fight it, use findlib!

In byte-code libraries can contains libraries, but not in native code.
