Thanks for the report.

Could you provide a sequence of shell commands that would allow to reproduce the problem?

I spot this error from a large project, it may be hard to reproduce in a minimal examlpe.
But it may be easy to verify this problem: by
ocamlbuild -verbose 1 binary.byte
and read the log
Here is a sample output

ocamlfind ocamldep -pp 'boot/fan -parser rf -parser debug -printer p -D OPT' -modules src/Camlp4/Struct/Grammar/Print.mli > src/Camlp4/Struct/Grammar/Print.mli.depends

It will not use Print.ml to generate dependency, if Print.mli is very succinct, it will not generate dependency correctly

I'm sorry, hongbo, but I'm afraid the issue would be quite hard to understand and debug without a test case. Please try to see if you can produce a test case, otherwise the bug is unlikely to go away from this report alone.

I agree with gasche, we need a repro case, even if it's a big one.

I would try to make a reproducible case by tuesday. The problem is that for small repos, it's hard to cause a failure

Sorry, I can not reproduce the problem any more, my repo was changed a lot(directory structure flattened).

But I remembered if I have two files Printer.ml Printer.mli, if I remove Printer.mli, then everything went smoothly. Sorry for the in-convenience.
