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()
some features of the UNIX filesystem regarding link count and file dates
inplace operation (the -i switch) without backup file
umask() works, but the correct permissions are only set when the file is finally close()d

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
