OCAMLDEP(1)OCAMLDEP(1)NAMEocamldep - Dependency generator for OCaml
SYNOPSISocamldep [ 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
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 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.
-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.
-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
dependencies cannot be used by make(1), but can be post-pro‐
cessed 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
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.
-ppx command
Pipe abstract syntax tree through preprocessor command.
-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.
