@EmileRolley if you invoke make build_french_law_library_ocaml -B you'll get an error message that corresponds to a bug in your JSOO wrapper plugin for the handling of context scope variables (both input and defined in the scope). Could you take a look at it next week ?

It seems related to the management both of the unit type and the duration which I missed because they don't appear in the allocations_familiales examples.

It should work now :)
