generating .cma-files with ocamlbuild

generating .cma-files with ocamlbuild

[Christian Sternagel]

Is there an easy way to tell ocamlbuild that it should
take some *.ml and *.mli files and build an archive
<name>.cma out of them?

Btw: I have another question concerning *.cma files.
Maybe an example is the easiest way to express this
question.

There are files:
set.mli set.ml setInternal.ml a.mli a.ml

I want to create the file util.cma which contains
set.cmo, setInternal.cmo, and a.cmo.

set.cmo uses setInternal.cmo but the user should
only be able to access modules Set and A but not
SetInternal. As far as I understud, this is done by
just providing set.cmi and a.cmi together with
util.cma.

Questions:
1) Is my understandung correct?
2) Can there be a problem if somebody using util.cma
(who does not know, that setInternal.cmo is part of
it) uses a self-made module by the name SetInternal
in his application?

cheers

Yes, just create a .mllib file that lists all the modules you want to
include in the .cma.

Yes, it is.

Indeed, the linker will complain about incompatible interfaces for the
same module name.
