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.
