During compilation, the following error occurs:
Unbound module Parsetree.
What's the reason ?
The --with-ocaml-src-dir=directory option of the configure script is used to indicate where the compiled sources of OCaml
are located. This directory is not the directory where OCaml is installed, but
the directory where OCaml sources were uncompressed and compiled. In particular
this option cannot be used with an OCaml installed from a linux distribution package.
