[Caml-list] Ocamldep too "gentle".

[Caml-list] Ocamldep too "gentle".

[David Brown]

I'm having a problem with ocamldep being too "gentle".  I have a file
units.ml that is generated with extract_crc.  The problem is that
ocamldep gets run at the beginning of the make, when units.ml doesn't
yet exist.  ocamldep doesn't output the dependency on units.cmo and
units.cmx because it can't find the source file.

I know that ocamldep doesn't have any way of knowing which directory the
dependency is to be located in, so I'm really just looking for
suggestions.

What about: write the dependencies of units.ml in the makefile?

Or you can try create an empty units.ml before calculate dependency

This would lead to wrong dependencies if they are not empty.

The solution is to generate units.ml before generating the
dependency.... 

You could try to look at what the OcamlMakefile do for ocamllex and
ocamlyacc generated ml file.

I had the same problem with packages (-pack), 
but since there is no source file at all, one cannot do something like
what does OCamlMakefile.

Currently, I do "touch toto.ml; ocamldep ...; rm toto.ml"

but I've also written the attached small patch to ocamldep, 
which add an option "-f <file>", allowing the user to force some
dependencies to be generated even if there is no .ml[i] file.


Hope this help,
damien
