NAME

SYNOPSIS

DESCRIPTION

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

-absname

Show absolute filenames in error messages.

-all

Generate dependencies on all required files, rather than assuming implicit dependencies.

-allow-approx

Allow falling back on a lexer-based approximation when parsing fails.

-as-map

For the following files, do not include delayed dependencies for module aliases. This option assumes that they are compiled using options "-no-alias-deps -w -49", and that those files or their interface are passed with the "-map" option when computing dependencies for other files. Note also that for dependencies to be correct in the implementation of a map file, its interface should not coerce any of the aliases it contains.

-debug-map

Dump the delayed dependency map for each map file.

-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 generated. For programs that span multiple directories, it is recommended to pass ocamldep(1) the same -I options that are passed to the compiler.

-impl file

Process file as a .ml file.

-intf file

Process file as a .mli file.

-map file

Read an propagate the delayed dependencies for module aliases in file, so that the following files will depend on the exported aliased modules if they use them.

-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 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.)

-one-line

Output one line per file, regardless of the length.

-open module

Assume that module module is opened before parsing each of the following files.

-plugin plugin

Dynamically load the code of the given plugin (a .cmo, .cma or .cmxs file) in ocamldep(1). The plugin must exist in the same kind of code as the tool ( ocamldep.byte must load bytecode plugins, while ocamldep.opt must load native code plugins), and extension adaptation is done automatically for .cma files (to .cmxs files if ocamldep(1) is compiled in native code).

-pp command

Cause ocamldep(1) to call the given command as a preprocessor for each source file.

-ppx command

Pipe abstract syntax tree through preprocessor command.

-slash

Under Unix, this option does nothing.

-sort

Sort files according to their dependencies.

-version

Print version string and exit.

-vnum

Print short version number and exit.

-help or --help

Display a short usage summary and exit.
