Hello,
playing with ocamlbuild, I manage to produce one "my.top" toplevel by
filling "my.mltop" with some module names (cmo), and asking for:
ocamlbuild my.top.
Now, instead of building a toplevel with cmo files, I would like to
build one with libraries (cma).
Is there any way to do this with oca
I replied off-list to Nicolas (by mistake) in order to insist, because
my question was not clear enough.
After some more readings, I would say that my goal was to generate a
custom toplevel by linking an

Hello,
during installation, one Caml module named Ocamlbuild_config is created
(at least when the ocamlbuild method is used).
Is this module installed anywhere, and are the values listed in it
accessible from an ocamlbuild plugin?
That would avoid to call ocamlc or ocamlopt and parse results.

Hello,
I was not able to compile and install correctly camlidl

Did anybody succeed, or should camlidl be adapted?

There is clearly a problem in my configuration or in flexlink, or both?
