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 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.
