=head1 DESCRIPTION

=head2 Prerequisites

=over 6

=item B<Unix emulation for AmigaOS: ixemul.library>

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

ixemul-45.1-bin.lha
ixemul-45.1-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 B<ADE> (the I<Amiga Developers Environment>).

=item B<Version of Amiga OS>

You need at the very least AmigaOS version 2.0. Recommended is version 3.1.

=back

=head2 Starting Perl programs under AmigaOS

Start your Perl program F<foo> with arguments C<arg1 arg2 arg3> the
same way as on any other platform, by

perl foo arg1 arg2 arg3

If you want to specify perl options C<-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 B<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 F</usr/bin/perl> is not
necessary, F<perl> would be enough, but having full path would make it
easier to use your script under *nix.)

=head1 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.

=head1 Accessing documentation

=head2 Manpages

If you have C<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 (F<.>) is used as a package separator for documentation
for packages, and as usual, sometimes you need to give the section - C<3>
above - to avoid shadowing by the I<less(1) manpage>.


=head2 B<HTML>

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

cd /ade/lib/perl5/pod
pod2html

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

Alternatively you may be able to get these docs prebuilt from C<CPAN>.

=head2 B<GNU> C<info> files

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

=head2 C<LaTeX> docs

can be constructed using C<pod2latex>.

=head1 BUILD

Here we discuss how to build Perl under AmigaOS.

=head2 Prerequisites

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

=head2 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 F<Configure>. This
is normal and expected. (There is a conflict with a similarly-named file
F<configure>, but it causes no harm.)

=head2 Making

  sh configure.gnu --prefix=/ade

Now

  make

=head2 Testing

Now run

  make test

Some tests will fail. Here is which, and why:

=over 8

=item F<io/fs.t>, F<op/stat.t>, F<lib/*dbm.t>, F<lib/db-*.t>

Check I<file system> operations. Failures result from the inability to
emulate some Unixisms with the standard Amiga filesystem.

=item F<io/pipe.t>, F<op/fork.t>, F<lib/filehand.t>, F<lib/open2.t>,
      F<lib/open3.t>, F<lib/io_pipe.t>, F<lib/io_sock.t>

These tests will be skipped because they use the fork() function, which is not
supported under AmigaOS.

=item F<op/magic.t>

The ixemul.library doesn't set the expected values for $0 and $^X.

=back

=head2 Installing the built perl

Run

  make install
