You're right this is a linking issue and now the question is at which level
you want to "link" your code. I do not see the point of including a cmo in
another like you describe : i believe there are simpler and mainstream
options. Maybe I miss some details about your problem ? Using findlib to
help the linker is one way to do it, but if you insist on loading a single
module then you have two other options :
- code inclusion -> m4, camlmix, camlp4 or any preprocessor (not that ugly,
but still)
- the -pack option for combining several cmo in a single one (but then all
your modules are included in a "toplevel" module)
sorry if i still didn't get your problem ;o).
