ocamldep - Dependency generator for Objective Caml


ocamldep [ options ] filename ...


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).


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 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 generated. For programs that span multiple directories, it is recommended to pass ocamldep(1) the same -I options that are passed to the compiler.
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).
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.
Under Unix, this option does nothing.
Print version and exit.
-help or --help
Display a short usage summary and exit.

Dans la mesure, me disais-je, où le langage rend compte de tout et où
tout ce qui, en principe, lui échappe (coutumes, rêves, cuisine,
vêtements, etc.) peut être ainsi annexé à son empire, c'est toujours, au
bout du compte, le sens qui triomphe.
Bien plus, tout ce qui, dans les oeuvres des hommes, nous a d'abord paru
barbare ou incohérent, bègue ou muet, obscur ou incompréhensible,
révoltant, voire tout à fait invisible ou tout à fait absent et comme
entaché du crime de Non-sens, finit par se ranger sur les étagères de
la Signification.
