ocamlfind-mini
----------------------------------------------------------------------
ocamlfind-mini is an OCaml script that implements a subset of the
full functionality of ocamlfind. It consists only of one file, so it
is easy to distribute it with any software.
The subset is normally sufficient to compile a library and to
install the library; but it is insufficient to link the library
into an executable.
----------------------------------------------------------------------
SUPPORTED OPERATING SYSTEMS:
----------------------------------------------------------------------
For Unixes, the script runs out of the box. It uses the ocaml system
found in the command path.
I think the script also runs in Windows, but I have not yet checked that.
Anyway, you cannot call it directly, but by doing
ocaml ocamlfind-mini <args>...
Macintosh is not supported; I don't have enough knowledge for a Mac port.
----------------------------------------------------------------------
FUNCTIONALITY:
----------------------------------------------------------------------
Overall: The configuration file ocamlfind.conf is ignored. However,
some environment variables are respected (see below).
A package directory is recognized by checking whether there is a META
file in it. However, the contents of that file are ignored.
The following subset has been implemented:
- ocamlfind-mini [ocamlc|ocamlopt|ocamlcp|ocamlmktop] <args>...
The -package option works, but you must set the environment variable
OCAMLPATH (see below).
The options -linkpkg, -predicates, -dontlink, -syntax, -ppopt are
rejected.
This normally means that you can compile modules as in:
ocamlfind-mini ocamlc -c -package p1,p2,p3 my_module.ml
However, you cannot create executables because -linkpkg is not
supported.
Note that ocamlfind-mini is unable to figure out the prerequisite
packages, so the -package option must enumerate _all_ needed packages.
Note that ocamlfind-mini does not support the alternate directory
layout where all META files are collected in one directory.
- ocamlfind-mini install <pkg> <file>...
Installs the files in the package directory for <pkg>. You must help
ocamlfind-mini by specifying the destination directory:
* Setting the -destdir option:
ocamlfind-mini install -destdir <dir> <pkg> <file> ...
This command installs the new package into <dir>/<pkg>.
* Setting the OCAMLFIND_DESTDIR variable:
export OCAMLFIND_DESTDIR=<dir>
ocamlfind-mini install <pkg> <file> ...
This command installs the new package into <dir>/<pkg>, too.
- ocamlfind-mini remove <pkg>
Removes the package <pkg>. Again, you must specify the destination
directory by either setting the -destdir option or by setting the
OCAMLFIND_DESTDIR variable.
----------------------------------------------------------------------
ENVIRONMENT:
----------------------------------------------------------------------
The following variables are supported:
- OCAMLPATH
A colon (Win: semicolon)-separated list of directories:
OCAMLPATH=<dir1>:<dir2>:...
When ocamlfind-mini searches a package <pkg>, it checks whether
<dirK>/<pkg>/META exists for K=1, 2, ...
- OCAMLFIND_DESTDIR
The destination directory for "install" and "remove".
- OCAMLFIND_METADIR
The destination directory for META files. It is not recommended to set
this variable.
