NAME
jocamldep - Dependency generator for JoCaml
SYNOPSIS
jocamldep [ -I lib-dir ] filename ...
DESCRIPTION
The jocamldep(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:
jocamldep options *.mli *.ml > .depend
where .depend is the file that should contain the dependencies.
Dependencies are generated both for compiling with the bytecode
compiler jocamlc(1) and with the native-code compiler jocamlopt(1).
OPTIONS
The following command-line option is recognized by jocamldep(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
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 form the standard
library, and no dependencies are generated. For programs that
span multiple directories, it is recommended to pass
jocamldep(1) the same -I options that are passed to the
compiler.
-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), jocamldep(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.)
