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.)
