perlmodinstall - Installing CPAN Modules

As shipped in IRIX 6.5.30. Added in IRIX 6.5.19.

NAME
     perlmodinstall - Installing CPAN Modules

DESCRIPTION
     You can think of a module as the fundamental unit of reusable Perl code;
     see the perlmod manpage for details.  Whenever anyone creates a chunk of
     Perl code that they think will be useful to the world, they register as a
     Perl developer at http://www.perl.com/CPAN/modules/04pause.html so that
     they can then upload their code to the CPAN.  The CPAN is the
     Comprehensive Perl Archive Network and can be accessed at
     http://www.perl.com/CPAN/.

     This documentation is for people who want to download CPAN modules and
     install them on their own computer.

     PREAMBLE

     You have a file ending in .tar.gz (or, less often, .zip).  You know
     there's a tasty module inside.  There are four steps you must now take:

     DECOMPRESS the file

     UNPACK the file into a directory

     BUILD the module (sometimes unnecessary)

     INSTALL the module.

     Here's how to perform each step for each operating system.  This is not a
     substitute for reading the README and INSTALL files that might have come
     with your module!

     Also note that these instructions are tailored for installing the module
     into your system's repository of Perl modules.  But you can install
     modules into any directory you wish.  For instance, where I say perl
     Makefile.PL, you can substitute perl Makefile.PL
     PREFIX=/my/perl_directory to install the modules into /my/perl_directory.
     Then you can use the modules from your Perl programs with use lib
     "/my/perl_directory/lib/site_perl"; or sometimes just use
     "/my/perl_directory";.

     o   If you're on Unix,

         You can use Andreas Koenig's CPAN module (
         http://www.perl.com/CPAN/modules/by-module/CPAN ) to automate the
         following steps, from DECOMPRESS through INSTALL.

         A. DECOMPRESS

         Decompress the file with gzip -d yourmodule.tar.gz

         You can get gzip from ftp://prep.ai.mit.edu/pub/gnu.
         Or, you can combine this step with the next to save disk space:

              gzip -dc yourmodule.tar.gz | tar -xof -

         B. UNPACK

         Unpack the result with tar -xof yourmodule.tar

         C. BUILD

         Go into the newly-created directory and type:

               perl Makefile.PL
               make
               make test

         D. INSTALL

         While still in that directory, type:

               make install

         Make sure you have the appropriate permissions to install the module
         in your Perl 5 library directory.  Often, you'll need to be root.

         That's all you need to do on Unix systems with dynamic linking.  Most
         Unix systems have dynamic linking -- if yours doesn't, or if for
         another reason you have a statically-linked perl, and the module
         requires compilation, you'll need to build a new Perl binary that
         includes the module.  Again, you'll probably need to be root.

     o   If you're running Windows 95 or NT with the ActiveState port of Perl

            A. DECOMPRESS

         You can use the shareware Winzip ( http://www.winzip.com ) to
         decompress and unpack modules.

            B. UNPACK

         If you used WinZip, this was already done for you.

            C. BUILD

         Does the module require compilation (i.e. does it have files that end
         in .xs, .c, .h, .y, .cc, .cxx, or .C)?  If it does, you're on your
         own.  You can try compiling it yourself if you have a C compiler.  If
         you're successful, consider uploading the resulting binary to the
         CPAN for others to use.  If it doesn't, go to INSTALL.

            D. INSTALL

         Copy the module into your Perl's lib directory.  That'll be one of
         the directories you see when you type

            perl -e 'print "@INC"'


     o   If you're running Windows 95 or NT with the core Windows distribution
         of Perl,

            A. DECOMPRESS

         When you download the module, make sure it ends in either .tar.gz or
         .zip.  Windows browsers sometimes download .tar.gz files as _tar.tar,
         because early versions of Windows prohibited more than one dot in a
         filename.

         You can use the shareware WinZip ( http://www.winzip.com ) to
         decompress and unpack modules.

         Or, you can use InfoZip's unzip utility (
         http://www.cdrom.com/pub/infozip/Info-Zip.html ) to uncompress .zip
         files; type unzip yourmodule.zip in your shell.

         Or, if you have a working tar and gzip, you can type

            gzip -cd yourmodule.tar.gz | tar xvf -

         in the shell to decompress yourmodule.tar.gz.  This will UNPACK your
         module as well.

            B. UNPACK

         All of the methods in DECOMPRESS will have done this for you.

            C. BUILD

         Go into the newly-created directory and type:

               perl Makefile.PL
               dmake
               dmake test

         Depending on your perl configuration, dmake might not be available.
         You might have to substitute whatever perl -V:make says. (Usually,
         that will be nmake or make.)

            D. INSTALL

         While still in that directory, type:

               dmake install

     o   If you're using a Macintosh,

         A. DECOMPRESS

         You can either use StuffIt Expander ( http://www.aladdinsys.com/ ) in
         combination with DropStuff with Expander Enhancer (shareware), or the
         freeware MacGzip (
         http://persephone.cps.unizar.es/general/gente/spd/gzip/gzip.html ).

         B. UNPACK

         If you're using DropStuff or Stuffit, you can just extract the tar
         archive.  Otherwise, you can use the freeware suntar (
         http://www.cirfid.unibo.it/~speranza ).

         C. BUILD

         Does the module require compilation?

         1. If it does,

         Overview: You need MPW and a combination of new and old CodeWarrior
         compilers for MPW and libraries.  Makefiles created for building
         under MPW use the Metrowerks compilers.  It's most likely possible to
         build without other compilers, but it has not been done successfully,
         to our knowledge.  Read the documentation in MacPerl: Power and Ease
         ( http://www.ptf.com/macperl/ ) on porting/building extensions, or
         find an existing precompiled binary, or hire someone to build it for
         you.

         Or, ask someone on the mac-perl mailing list (mac-
         perl@iis.ee.ethz.ch) to build it for you.  To subscribe to the mac-
         perl mailing list, send mail to mac-perl-request@iis.ee.ethz.ch.

         2. If the module doesn't require compilation, go to INSTALL.

         D. INSTALL

         Make sure the newlines for the modules are in Mac format, not Unix
         format.  Move the files manually into the correct folders.

         Move the files to their final destination: This will most likely be
         in $ENV{MACPERL}site_lib: (i.e., HD:MacPerl folder:site_lib:).  You
         can add new paths to the default @INC in the Preferences menu item in
         the MacPerl application ($ENV{MACPERL}site_lib: is added
         automagically).  Create whatever directory structures are required
         (i.e., for Some::Module, create $ENV{MACPERL}site_lib:Some: and put
         Module.pm in that directory).

         Run the following script (or something like it):

              #!perl -w
              use AutoSplit;
              my $dir = "${MACPERL}site_perl";
              autosplit("$dir:Some:Module.pm", "$dir:auto", 0, 1, 1);

         Eventually there should be a way to automate the installation
         process; some solutions exist, but none are ready for the general
         public yet.

     o   If you're on the DJGPP port of DOS,

            A. DECOMPRESS

         djtarx ( ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2/ ) will both
         uncompress and unpack.

            B. UNPACK

         See above.

            C. BUILD

         Go into the newly-created directory and type:

               perl Makefile.PL
               make
               make test

         You will need the packages mentioned in Readme.dos in the Perl
         distribution.

            D. INSTALL

         While still in that directory, type:

              make install

         You will need the packages mentioned in Readme.dos in the Perl distribution.


     o   If you're on OS/2,

         Get the EMX development suite and gzip/tar, from either Hobbes (
         http://hobbes.nmsu.edu ) or Leo ( http://www.leo.org ), and then
         follow the instructions for Unix.

     o   If you're on VMS,

         When downloading from CPAN, save your file with a .tgz extension
         instead of .tar.gz.  All other periods in the filename should be
         replaced with underscores.  For example, Your-Module-1.33.tar.gz
         should be downloaded as Your-Module-1_33.tgz.
         A. DECOMPRESS

         Type

             gzip -d Your-Module.tgz

         or, for zipped modules, type

             unzip Your-Module.zip

         Executables for gzip, zip, and VMStar ( Alphas:
         http://www.openvms.digital.com/cd/000TOOLS/ALPHA/ and Vaxen:
         http://www.openvms.digital.com/cd/000TOOLS/VAX/ ).

         gzip and tar are also available at ftp://ftp.digital.com/pub/VMS.

         Note that GNU's gzip/gunzip is not the same as Info-ZIP's zip/unzip
         package.  The former is a simple compression tool; the latter permits
         creation of multi-file archives.

         B. UNPACK

         If you're using VMStar:

              VMStar xf Your-Module.tar

         Or, if you're fond of VMS command syntax:

              tar/extract/verbose Your_Module.tar

         C. BUILD

         Make sure you have MMS (from Digital) or the freeware MMK ( available
         from MadGoat at  http://www.madgoat.com ).  Then type this to create
         the DESCRIP.MMS for the module:

             perl Makefile.PL

         Now you're ready to build:

             mms
             mms test

         Substitute mmk for mms above if you're using MMK.

         D. INSTALL

         Type

             mms install

         Substitute mmk for mms above if you're using MMK.
     o   If you're on MVS,

         Introduce the .tar.gz file into an HFS as binary; don't translate
         from ASCII to EBCDIC.

         A. DECOMPRESS

               Decompress the file with C<gzip -d yourmodule.tar.gz>

               You can get gzip from
               http://www.s390.ibm.com/products/oe/bpxqp1.html.

         B. UNPACK

         Unpack the result with

              pax -o to=IBM-1047,from=ISO8859-1 -r < yourmodule.tar

         The BUILD and INSTALL steps are identical to those for Unix.  Some
         modules generate Makefiles that work better with GNU make, which is
         available from http://www.mks.com/s390/gnu/index.htm.

HEY
     If you have any suggested changes for this page, let me know.  Please
     don't send me mail asking for help on how to install your modules.  There
     are too many modules, and too few Orwants, for me to be able to answer or
     even acknowledge all your questions.  Contact the module author instead,
     or post to comp.lang.perl.modules, or ask someone familiar with Perl on
     your operating system.
