NAME

       findlib.conf - [Configuration of findlib/ocamlfind]

GENERAL

       There are three possibilities to configure the findlib library:

         Build time:

              Before  findlib  is compiled, a "configure" script is invoked to
              figure  out the settings that are most likely  to  work  on  the
              system.  Most    settings are simply entered into text files and
              can  easily  be  changed    after  installation.  The  following
              properties  cannot  be  changed later  because they are compiled
              into the resulting binaries:

                  o  The  default   location   of   the   configuration   file
                     findlib.conf.  However,  you can set a different location
                     by the environment variable  OCAMLFIND_CONF.

                  o  Whether the installed O'Caml version supports autolinking
                     or not.

         Configuration file findlib.conf:

              An  initial  version  of this file is generated by the configure
              script,  but you are free to modify it  later.  Most  important,
              this  file  contains the system-wide search path used to look up
              packages, and  the    default  location  where  to  install  new
              packages.

              All  files  with  the  suffix  ".conf"  found  in the directory
              findlib.conf.d are also scanned for parameters.

         Environment variables:

              The settings of findlib.conf can be  overridden  by  environment
              variables.

       Last but not least, several settings can also be passed as command-line
       options, or by invoking the function Findlib.init.

findlib.conf

       The directory containing findlib.conf is determined at build  time  (by
       running  the configure script), the fallback default is /usr/local/etc.
       You can set a different location by changing the  environment  variable
       OCAMLFIND_CONF which must contain the absolute path of findlib.conf.

       The  file  has the same syntax as META, i.e. it consists of a number of
       lines with the format

       variable = "value"

       Here is the list of allowed variables:

         path

              The search path for META files/package directories. The variable
               enumerates directories which are separated by colons (Windows:
              semicolons), and these directories are tried in turn to  find  a
              certain    package. More exactly, if d is such a directory and p
              the searched  package, the search  algorithm  will  first  check
              whether d/p/META  exists. In this case, this META file is taken,
              and d/p is the package  directory. Second, the  algorithm  tries
              d/META.p,  but  the package  directory must be specified in this
              META.p file by a  directory directive.

              Note that the first found META file is taken, so  the  order  of
              the  directories in the search path counts.

              This variable is required.

              Example:

              path = "/usr/local/lib/ocaml/site-lib:/usr/lib/ocaml/site-lib"

         destdir

              This  variable  determines the location where ocamlfind  install
              puts the packages by default: If d is this  directory, and p the
              package  to  install,  a  new  subdirectory d/p will  be created
              containing all the files of the package.

              Example:

              destdir = "/usr/local/lib/ocaml/site-lib"

              This variable is required.

         metadir

              If set, the command ocamlfind install will put the   META  files
              of  packages  into this directory (files are named META.p  where
              p=package name); otherwise the META files  are  put  into  the
              package directories like any other file.

              Example:

              metadir = "/var/lib/findlib/metaregistry"

              This variable is optional. It is not used by default.

         ocamlc,    ocamlopt,    ocamlcp,   ocamlmktop,  ocamldoc,  ocamldep,
         ocamlbrowser

              If you want to call other executables than "ocamlc", "ocamlopt",
                 "ocamlcp",   "ocamlmktop",   "ocamldoc",   "ocamldep",  and
              "ocamlbrowser", you can  set the names of  the executables here.
              The  command  ocamlfind  looks    into  these  four variables to
              determine the names of the compilers to  call.

              Example:

              ocamlc     = "ocamlc.opt"
              ocamlopt   = "ocamlopt.opt"
              ocamlcp    = "ocamlcp.opt"
              ocamlmktop = "ocamlmktop.opt"

              This variable is optional. It is not used by default.

         stdlib

              This variable determines the location of the  standard  library.
              This  must  be the same directory for which the O'Caml compilers
              are configured.

              This variable is optional. It  is  not  recommend  to  set  this
              variable  unless you know what you are doing!

         ldconf

              This  variable determines the location of the ld.conf file. This
              must  be the same file the  O'Caml  compilers  read  in;  it  is
              updated  by     ocamlfind when installing and removing packages.
              You can set this  variable to  the  special  value  "ignore"  to
              disable  the automatic modification of the ld.conf file.

              If not set, the ld.conf file is assumed to reside in the O'Caml
              standard library directory.

              This variable is optional. It is not  recommended  to  set  this
              variable  unless you know what you are doing!

       Toolchains:   It   is   possible  to  have  variants  of  the  original
       configuration. These variants are called "toolchains" because they  are
       intended  to  select  different  compilers,  e.g. patched compilers. In
       order to set a variable for a certain toolchain, use the syntax

       variable(toolchain) = "value"
         For example:

       ocamlc(mypatch) = "ocamlc-mypatch"
         When the toolchain "mypatch" is selected, this compiler will be  used
       instead of the standard one.

       In order to switch to a certain toolchain, use the -toolchain option of
       ocamlfind.

Environment

       A  number  of  environment  variables   modifies   the   behaviour   of
       findlib/ocamlfind:

         OCAMLFIND_CONF

              This  variable overrides the location of the configuration file
              findlib.conf. It must contain the absolute  path  name  of  this
              file.

         OCAMLPATH

              This variable may contain an additional search path for package
              directories. It is treated as if the directories were  prepended
              to  the configuration variable path.

         OCAMLFIND_DESTDIR

              This variable overrides the configuration variable  destdir.

         OCAMLFIND_METADIR

              This variable overrides the configuration variable  metadir.

         OCAMLFIND_COMMANDS

              This  variable  overrides  the  configuration variables  ocamlc,
              ocamlopt,  ocamlcp, ocamlmktop,   ocamldoc,  ocamldep,  and/or
              ocamlbrowser.    Its value must conform to the syntax

              ocamlc=name ocamlopt=name ocamlcp=name ocamlmktop=name ocamldoc=name ocamldep=name ocamlbrowser=name

              Example:

              ocamlc=ocamlc-3.00 ocamlopt=ocamlopt-3.00 ocamlcp=ocamlcp-3.00 ocamlmktop=ocamlmktop-3.00

         CAMLLIB or OCAMLLIB

              This variable overrides the configuration variable  stdlib.

         OCAMLFIND_LDCONF

              This variable overrides the configuration variable  ldconf.

         OCAMLFIND_IGNORE_DUPS_IN

              This  variable  instructs  findlib  not  to  emit  warnings that
              packages  or module occur several times. The  variable  must  be
              set  to  the  directory where the packages reside that are to be
              ignored for this  warning.
