Compiling this repo
- Make sure you have OCaml and GNU make installed.
make lib-extas advertised by
./configureif you don't have the dependencies installed and only need the opam binary (not the libs). This will locally take care of all OCaml dependencies for you.
- Otherwise, make sure to have ocamlfind, ocamlgraph, cmdliner, cudf,
dose 3.2.2+opam and re >= 1.2.0 installed. Or run
opam install opam-lib --deps-onlyif you already have a working instance. Re-run
make libinstallif needed (this is incompatible with
make lib-ext, as the opam library would conflict with installed versions of the dependencies)
