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.)
