1 dnl autoconf macros for OCaml
3 dnl modified by Richard W.M. Jones
4 dnl from a configure.in by Jean-Christophe FilliĆ¢tre,
5 dnl from a first script by Georges Mariano
7 dnl defines AC_PROG_OCAML that will check the OCaml compiler
8 dnl and set the following variables :
9 dnl OCAMLC "ocamlc" if present in the path, or a failure
10 dnl or "ocamlc.opt" if present with same version number as ocamlc
11 dnl OCAMLOPT "ocamlopt" (or "ocamlopt.opt" if present), or "no"
12 dnl OCAMLBEST either "byte" if no native compiler was found,
13 dnl or "opt" otherwise
14 dnl OCAMLDEP "ocamldep"
15 dnl OCAMLLIB the path to the ocaml standard library
16 dnl OCAMLVERSION the ocaml version number
