NAME
ocamlbuild - The Objective Caml project compilation tool
SYNOPSIS
ocamlbuild [ -Is dir1,... ] [ -libs lib1,... ] [ -lflags flag1,...
] [ -pp flags ] [ -tags tag1,... ] [ -j parallel-jobs ] target.native
[ -- arg1 arg2 ... ]
(same options)
DESCRIPTION
ocamlbuild(1) orchestrates the compilation process of your OCaml
project. It is similar in function to make(1) except that it is
tailor-made to automatically compile most OCaml projects with very
little user input.
ocamlbuild should be invoked in the root of a clean project tree (e.g.,
with no leftover compilation files). Given one or more targets to
compile, it scans the required subdirectories to gather information
about the various files present, running tools such as ocamldep(1) to
extract dependency information, and gathering optional files that fine-
tune its behaviour. Target names are very significant.
TARGET NAMES
ocamlbuild uses a set of target naming conventions to select the kind
of objects to produce. Target names are of the form base.extension
where base is usually the name of the underlying Ocaml module and
extension denotes the kind of object to produce from that file -- a
byte code executable, a native executable, documentation... Of course
extensions such as .cmo, .cma, .cmi... map to their usual
counterparts. Here is a list of the most important ocamlbuild-specific
extensions:
.native Native code executable
.byte Byte code executable
.inferred.mli Interface inferred with ocamlc-i
.docdir/index.html HTML documentation generated with ocamldoc
