OCAMLDEP(1) General Commands Manual 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 references to external compilation units, and outputs depen-
dency lines in a format suitable for the make(1) utility. This ensures
that make will compile the source files in the correct order, and re-
compile 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 com-
piler ocamlc(1) and with the native-code compiler ocamlopt(1).
OPTIONS
The following command-line options are recognized by ocamldep(1).
-absname
Show absolute filenames in error messages.
-all Generate dependencies on all required files, rather than assum-
ing 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 us-
ing 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 com-
pilation 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. Oth-
erwise, Bar is assumed to be a module from the standard library,
and no dependencies are generated. For programs that span multi-
ple directories, it is recommended to pass ocamldep(1) the same
-I options that are passed to the compiler.
-nocwd Do not add current working directory to the list of include di-
rectories.
-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 Mod-
ule2 ... 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 de-
pendencies 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 byte-
code version). When an implementation file (.ml file) has no
explicit interface file (.mli file), ocamldep(1) generates de-
pendencies on the bytecode compiled file (.cmo file) to reflect
interface changes. This can cause unnecessary bytecode recompi-
lations 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.
-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.
-shared
Generate dependencies for native plugin files (.cmxs) in addi-
tion to native compiled files (.cmx).
-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.
