Error when installing ocamlfind with ocamljava

[antoine1fr]

Hi,

I've just installed ocamljava on opam 1.2.0 with the following commands:

opam remote add ocj http://opam.ocamljava.org
opam switch ocamljava-2.0-alpha2
eval `opam config env`

When trying to install ocamlfind I get the following error listing:

Building ocamlfind.1.5.5:

Here is my config:

• OS X 10.10
• opam 1.2.0
• java 1.8.0_25-b17

Do you have any idea where the error could come from?

Thanks

Indeed, you have to use a patched version of ocamlfind.
From the opam repository, you can install a draft vesion
through opam install ocamlfind-ocj. This draft is based
on version 1.4.0, and will be updated to the last version
in OCaml-JAva alpha3 (hopefully available this month).

Thanks for your answer! I'll try this ASAP. :)

The new 2.0-alpha3 version comes with a new ocamlfind
package (version 1.5.5), available under the name ocj-ocamlfind.
