The OCaml API for Z3 was tested using OCaml 3.12.1.
You also need CamlIDL to be able to generate the OCaml API.
- To download OCaml:
http://caml.inria.fr/ocaml/
- To download CamlIDL:
http://forge.ocamlcore.org/projects/camlidl/
- To build the OCaml API for Z3:
./build-lib.sh
Remark: The OCaml and C compiler tool chains must be configured in your environment.
Remark: Building the OCaml API copies some pathnames into files,
so the OCaml API must be recompiled if the Z3 library files are moved.
See ../examples/ocaml/build-test.sh for an example of how to compile and link with Z3.
Acknowledgements:
The OCaml interface for Z3 was written by Josh Berdine and Jakob Lichtenberg.
Many thanks to them!

Summary: Retrieve congruence class representatives for terms.
The function can be used for relying on Z3 to identify equal terms under the current
set of assumptions. The array of terms and array of class identifiers should have
the same length. The class identifiers are numerals that are assigned to the same
value for their corresponding terms if the current context forces the terms to be
equal. You cannot deduce that terms corresponding to different numerals must be all different,
(especially when using non-convex theories).
All implied equalities are returned by this call.
This means that two terms map to the same class identifier if and only if
the current context implies that they are equal.
A side-effect of the function is a satisfiability check on the assertions on the solver that is passed in.
The function return L_FALSE if the current assertions are not satisfiable.
