ocamlfind won't build with ocamljava

[arlencox]

When I try to build ocamlfind using the ocaml built with ocamljava I get an inconsistent assumptions over interface errors:

File "topfind.ml", line 1:
# Error: The files /Users/cox/.opam/ocamljava-2.0-alpha3/lib/ocaml/compiler-libs/toploop.cmi
#        and /Users/cox/.opam/ocamljava-2.0-alpha3/lib/ocaml/compiler-libs/parsetree.cmi
#        make inconsistent assumptions over interface Warnings
# make[1]: *** [topfind.cmo] Error 2

I tried to figure out how to fix it, but I couldn't figure out how to make the pieces of the build work outside of build.sh

Indeed; ocamlfind has to be patched to be compiled with ocamljava.
There is a dedicated opam package, namely ocj-ocamlfind.

Did you try to install ocamlfind thourgh opam install ocj-ocamlfind?

I didn't. I will try that. Is there a reason why these interfaces cannot make consistent assumptions?

The problem is that ocamljava defines new warnings.

In order to have a uniform handling, these new warnings are added as
new cases to the sum type of legacy warnings, hence modifying the
signature of the Warnings module.
