You mean how to solve in OCaml problems people solve using type-classes
in haskell ? 
 - For Eq,  ocaml has a polymorphic = 
 - For Ord, ocaml has a polymprohic <
 - For Show, there is sexplib, json-static, ocaml Dumper
 - Otherwise there is classes and module/functors, or just passing
   record containg functions,  which can mimic sometimes what type classes provides.

If you want real type-classes in OCaml, join the long list of people begging
for Xavier-Leroy/Vouillon/Doligez/Guarrigue/real-programmers...  to implement it 
(this list of begging people usually includes people who are too 
lazy/incompetent/afraid-to-look-in-ocaml-source to implement and rely on other
busy people to do the job).
