ocamlbuild is:

OCamlbuild is a generic build tool, which has built-in rules for building OCaml libraries and programs.

It was distributed as part of the OCaml distribution for OCaml versions between 3.10.0 and 4.02.3. Starting from OCaml 4.03, it is now released separately.

Its job is to determine the sequence of calls to the compiler with the right set of command-line flags needed to build your OCaml-centric software project.

It was designed as a generic build system (it is in fact not OCaml-specific), but also to be expressive enough to cover the specifics of the OCaml language that make writing good Makefiles difficult, such as the dreaded “units Foo and Bar make inconsistent assumptions about Baz” error.

To fix this problem, we can install more using the command below.

sudo apt-get -y install ocamlbuild

This command might take some time to finish depending on your machine internet connection.
