To compile and run the examples suite you must first have installed the library via OPAM. In order to build the suite simply invoke dune, i.e.

$ dune build

After successfully building the suite you can run each example via dune, which will run either the native or bytecode version of an example depending on which suffix you supply, e.g. to run the native version type

$ dune exec ./nqueens.exe

and for the bytecode version type

$ dune exec ./nqueens.bc.exe
