This is the ocaml tutorial example. It assumes that you've already built and installed the thrift ocaml runtime libraries in lib/ocaml.
To compile this, you will need to generate the Thrift sources for ocaml in this directory (due to limitations in the OASIS build-tool):
% thrift -r --gen ocaml ../tutorial.thrift % oasis setup % make
This will produce two executables Calc{Server,Client}. where is one of “byte” or “native”, depending on your ocaml installation. Just run the server in the background, then the client (as you would do for the C++ example).
