NAME

     perlamiga - Perl under Amiga OS



SYNOPSIS
     One can read this document in the following formats:

             man perlamiga
             multiview perlamiga.guide

     to list some (not all may be available simultaneously), or
     it may be read as is: either as README.amiga, or
     pod/perlamiga.pod.



DESCRIPTION
     Prerequisites

     Unix emulation for AmigaOS: ixemul.library
           You need the Unix emulation for AmigaOS, whose most
           important part is ixemul.library. For a minimum setup,
           get the following archives from
           ftp://ftp.ninemoons.com/pub/ade/current or a mirror:

           ixemul-46.0-bin.lha ixemul-46.0-env-bin.lha pdksh-
           4.9-bin.lha ADE-misc-bin.lha

           Note that there might be newer versions available by
           the time you read this.

           Note also that this is a minimum setup; you might want
           to add other packages of ADE (the Amiga Developers
           Environment).

     Version of Amiga OS
           You need at the very least AmigaOS version 2.0.
           Recommended is version 3.1.

     Starting Perl programs under AmigaOS

     Start your Perl program foo with arguments `arg1 arg2 arg3'
     the same way as on any other platform, by

             perl foo arg1 arg2 arg3

     If you want to specify perl options `-my_opts' to the perl
     itself (as opposed to to your program), use

             perl -my_opts foo arg1 arg2 arg3

     Alternately, you can try to get a replacement for the
     system's Execute command that honors the #!/usr/bin/perl
     syntax in scripts and set the s-Bit of your scripts. Then
     you can invoke your scripts like under UNIX with
             foo arg1 arg2 arg3

     (Note that having *nixish full path to perl /usr/bin/perl is
     not necessary, perl would be enough, but having full path
     would make it easier to use your script under *nix.)

     Shortcomings of Perl under AmigaOS

     Perl under AmigaOS lacks some features of perl under UNIX
     because of deficiencies in the UNIX-emulation, most notably:

     fork()

file dates
     some features of the UNIX filesystem regarding link count and

     inplace operation (the -i switch) without backup file

file is finally close()d
     umask() works, but the correct permissions are only set when the



INSTALLATION
     Change to the installation directory (most probably ADE:),
     and extract the binary distribution:

     lha -mraxe x perl-5.003-bin.lha

     or

     tar xvzpf perl-5.003-bin.tgz

     (Of course you need lha or tar and gunzip for this.)

     For installation of the Unix emulation, read the appropriate
     docs.



Accessing documentation
     Manpages

     If you have `man' installed on your system, and you
     installed perl manpages, use something like this:

             man perlfunc
             man less
             man ExtUtils.MakeMaker

     to access documentation for different components of Perl.
     Start with

             man perl

     Note: You have to modify your man.conf file to search for
     manpages in the /ade/lib/perl5/man/man3 directory, or the
     man pages for the perl library will not be found.

     Note that dot (.) is used as a package separator for
     documentation for packages, and as usual, sometimes you need
     to give the section - `3' above - to avoid shadowing by the
     less(1) manpage.

     HTML

     If you have some WWW browser available, you can build HTML
     docs.  Cd to directory with .pod files, and do like this

             cd /ade/lib/perl5/pod
             pod2html

     After this you can direct your browser the file perl.html in
     this directory, and go ahead with reading docs.

     Alternatively you may be able to get these docs prebuilt
     from `CPAN'.

     GNU `info' files

     Users of `Emacs' would appreciate it very much, especially
     with `CPerl' mode loaded. You need to get latest `pod2info'
     from `CPAN', or, alternately, prebuilt info pages.

     `LaTeX' docs

     can be constructed using `pod2latex'.



BUILD
     Here we discuss how to build Perl under AmigaOS.

     Prerequisites

     You need to have the latest ADE (Amiga Developers
     Environment) from ftp://ftp.ninemoons.com/pub/ade/current.
     Also, you need a lot of free memory, probably at least 8MB.

     Getting the perl source

     You can either get the latest perl-for-amiga source from
     Ninemoons and extract it with:

       tar xvzpf perl-5.004-src.tgz

     or get the official source from CPAN:

       http://www.perl.com/CPAN/src/5.0

     Extract it like this

       tar xvzpf perl5.004.tar.gz

     You will see a message about errors while extracting
     Configure. This is normal and expected. (There is a conflict
     with a similarly-named file configure, but it causes no
     harm.)

     Making

       sh configure.gnu --prefix=/ade

     Now

       make


     Testing

     Now run

       make test

     Some tests will be skipped because they need the fork()
     function:

     io/pipe.t, op/fork.t, lib/filehand.t, lib/open2.t,
     lib/open3.t, lib/io_pipe.t, lib/io_sock.t

     Installing the built perl

     Run

       make install
