OCAMLDEP(1)									      OCAMLDEP(1)

NAME
       ocamldep - Dependency generator for OCaml

SYNOPSIS
       ocamldep [ options ] filename ...

DESCRIPTION
       The  ocamldep(1) command scans a set of OCaml source files (.ml and .mli files) for refer-
       ences 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 compilation unit Bar, a dependency on  that
	      unit's  interface  bar.cmi  is generated only if the source for bar is found in the
	      current directory 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 gener-
	      ated. 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 compilation 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 dependen-
	      cies 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.
