Build time:c

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

Configuration file findlib.conf:c

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

Environment variables:c

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

pathc

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

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

This variable is required.c      

Example:c         

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

     

destdirc

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

Example:c      

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

     

This variable is required.c      

metadirc

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

Example:c      

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

     

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

ocamlcc ,c       ocamloptc ,c       ocamlcpc ,c       ocamlmktopc ,c       ocamldocc ,c       ocamldepc ,c       ocamlbrowserc      

If you want to call other executables than "ocamlc", "ocamlopt",c    "ocamlcp", "ocamlmktop", "ocamldoc", "ocamldep", andc    "ocamlbrowser", you canc    set the names ofc    the executables here. The command ocamlfindc looksc    into these four variables to determine the names of the compilers toc    call.c      

Example:c      

ocamlc     = "ocamlc.opt"c


ocamlopt   = "ocamlopt.opt"c


ocamlcp    = "ocamlcp.opt"c


ocamlmktop = "ocamlmktop.opt"c

     

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

stdlibc

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

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

ldconfc

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

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

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

OCAMLFIND_CONFc

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

OCAMLPATHc

This variable may contain an additional search path for packagec    directories. It is treated as if the directories were prepended toc    the configuration variable pathc .c      

OCAMLFIND_DESTDIRc

This variable overrides the configuration variablec       destdirc .      

OCAMLFIND_METADIRc

This variable overrides the configuration variablec       metadirc .      

OCAMLFIND_COMMANDSc

This variable overrides the configuration variablesc       ocamlcc , ocamloptc ,c       ocamlcpc , ocamlmktopc ,c       ocamldocc , ocamldepc , and/orc       ocamlbrowserc .    Its value must conform to the syntaxc         

ocamlc=c

namec ocamlopt=c namec ocamlcp=c namec ocamlmktop=c namec ocamldoc=c namec ocamldep=c namec ocamlbrowser=c namec      

Example:c      

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

     

CAMLLIBc or OCAMLLIBc

This variable overrides the configuration variablec       stdlibc .      

OCAMLFIND_LDCONFc

This variable overrides the configuration variablec       ldconfc .
