=head1 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 I<as is>: either as F<README.amiga>, or F<pod/perlamiga.pod>.

=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 latest versions
|
|
of the following packages from the Aminet archives
|
|
( L<http://www.aminet.net/~aminet/> ):
|
|
|
|
ixemul-bin
|
|
ixemul-env-bin
|
|
pdksh-bin
|
|
|
|
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.
|
|
|
|

|
|
|
|
=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 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.)
|
|
|
|
=head2 Shortcomings of Perl under AmigaOS
|
|
|
|
Perl under AmigaOS lacks some features of perl under UNIX because of
|
|
deficiencies in the UNIX-emulation, most notably:
|
|
|
|
=over 6
|
|
|
|
=item *
|
|
|
|
fork()
|
|
|
|
=item *
|
|
|
|
some features of the UNIX filesystem regarding link count and file dates
|
|
|
|
=item *
|
|
|
|
inplace operation (the -i switch) without backup file
|
|
|
|
=item *
|
|
|
|
umask() works, but the correct permissions are only set when the file is
|
|
finally close()d
|
|
|
|
=back
|
|
|
|
=head1 INSTALLATION
|
|
|
|
Change to the installation directory (most probably ADE:), and
|
|
extract the binary distribution:
|
|
|
|
lha -mraxe x perl-$VERSION-bin.lha
|
|
|
|
or
|
|
|
|
tar xvzpf perl-$VERSION-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 for Perl on AmigaOS
|
|
|
|
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 Perl HTML Documentation on AmigaOS
|
|
|
|
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 Perl GNU Info Files on AmigaOS
|
|
|
|
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 Perl LaTeX Documentation on AmigaOS
|
|
|
|
Can be constructed using C<pod2latex>.
|
|
|
|
=head1 BUILDING PERL ON AMIGAOS
|
|
|
|
Here we discuss how to build Perl under AmigaOS.
|
|
|
|
=head2 Build Prerequisites for Perl on AmigaOS
|
|
|
|
You need to have the latest B<ixemul> (Unix emulation for Amiga)
|
|
from Aminet.
|
|
|
|
=head2 Getting the Perl Source for AmigaOS
|
|
|
|
You can either get the latest perl-for-amiga source from Ninemoons
|
|
and extract it with:
|
|
|
|
tar xvzpf perl-$VERSION-src.tgz
|
|
|
|
or get the official source from CPAN:
|
|
|
|
http://www.cpan.org/src/5.0
|
|
|
|
Extract it like this
|
|
|
|
tar xvzpf perl-$VERSION.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 Perl on AmigaOS
|
|
|
|
Remember to use a hefty wad of stack (I use 2000000)
|
|
|
|
sh configure.gnu --prefix=/gg
|
|
|
|
Now type
|
|
|
|
make depend
|
|
|
|
Now!
|
|
|
|
make
|
|
|
|
=head2 Testing Perl on AmigaOS
|
|
|
|
Now run
|
|
|
|
make test
|
|
|
|
Some tests will be skipped because they need the fork() function:
|
|
|
|
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>
|
|
|
|
=head2 Installing the built Perl on AmigaOS
|
|
|
|
Run
|
|
|
|
make install
|
|
|
|
=head1 PERL 5.8.0 BROKEN IN AMIGAOS
|
|
|
|
As told above, Perl 5.6.1 was still good in AmigaOS, as was 5.7.2.
|
|
After Perl 5.7.2 (change #11423, see the Changes file, and the file
|
|
pod/perlhack.pod for how to get the individual changes) Perl dropped
|
|
its internal support for vfork(), and that was very probably the step
|
|
that broke AmigaOS (since the ixemul library has only vfork).
|
|
The build finally fails when the ext/DynaLoader is being built, and
|
|
PERL ends up as "0" in the produced Makefile, trying to run "0" does
|
|
not quite work. Also, executing miniperl in backticks seems to
|
|
generate nothing: very probably related to the (v)fork problems.
|
|
B<Fixing the breakage requires someone quite familiar with the ixemul
|
|
library, and how one is supposed to run external commands in AmigaOS
|
|
without fork().>
