OCAMLDEP(1) General Commands Manual OCAMLDEP(1)
NAME
ocamldep - Dependency generator for Objective Caml
SYNOPSIS
ocamldep [ options ] filename ...
DESCRIPTION
The ocamldep(1) command scans a set of Objective Caml source files (.ml and .mli files) for references to external compilation units, and
outputs dependency lines in a format suitable for the make(1) utility. This ensures that make will compile the source files in the correct
order, and recompile those files that need to when a source file is modified.
The typical usage is:
ocamldep options *.mli *.ml > .depend
where .depend is the file that should contain the dependencies.
Dependencies are generated both for compiling with the bytecode compiler ocamlc(1) and with the native-code compiler ocamlopt(1).
OPTIONS
The following command-line options are recognized by ocamldep(1).
-I directory
Add the given directory to the list of directories searched for source files. If a source file foo.ml mentions an external compila-
tion unit Bar, a dependency on that unit's interface bar.cmi is generated only if the source for bar is found in the current direc-
tory or in one of the directories specified with -I. Otherwise, Bar is assumed to be a module from the standard library, and no
dependencies are generated. For programs that span multiple directories, it is recommended to pass ocamldep(1) the same -I options
that are passed to the compiler.
-ml-synonym .ext
Consider the given extension (with leading dot) to be a synonym for .ml.
-mli-synonym .ext
Consider the given extension (with leading dot) to be a synonym for .mli.
-modules
Output raw dependencies of the form filename: Module1 Module2 ... ModuleN where Module1, ..., ModuleN are the names of the compila-
tion units referenced within the file filename, but these names are not resolved to source file names. Such raw dependencies cannot
be used by make(1), but can be post-processed by other tools such as Omake(1).
-native
Generate dependencies for a pure native-code program (no bytecode version). When an implementation file (.ml file) has no explicit
interface file (.mli file), ocamldep(1) generates dependencies on the bytecode compiled file (.cmo file) to reflect interface
changes. This can cause unnecessary bytecode recompilations for programs that are compiled to native-code only. The flag -native
causes dependencies on native compiled files (.cmx) to be generated instead of on .cmo files. (This flag makes no difference if all
source files have explicit .mli interface files.)
-pp command
Cause ocamldep(1) to call the given command as a preprocessor for each source file.
-slash Under Unix, this option does nothing.
-version
Print version string and exit.
-vnum Print short version number and exit.
-help or --help
Display a short usage summary and exit.
