NAME
perlamiga - Perl under Amiga OS
NOTE
Perl 5.8.0 cannot be built in AmigaOS. You can use either
the maintenance release Perl 5.6.1 or the development
release Perl 5.7.2 in AmigaOS. See "PERL 5.8.0 BROKEN IN
AMIGAOS" if you want to help fixing this problem.

DESCRIPTION
Prerequisites for Compiling Perl on AmigaOS
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 latest versions of the following packages from
the Aminet archives ( 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 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
perl v5.12.5 Last change: 2012-11-03 1
Perl Programmers Reference Guide PERLAMIGA(1)
If you want to specify perl options "-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 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:
o fork()
o some features of the UNIX filesystem regarding link
count and file dates
o inplace operation (the -i switch) without backup file
o 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-$VERSION-bin.lha
or
tar xvzpf perl-$VERSION-bin.tgz
(Of course you need lha or tar and gunzip for this.)
For installation of the Unix emulation, read the appropriate
docs.
Accessing documentation
Manpages for Perl on AmigaOS
If you have "man" installed on your system, and you
installed perl manpages, use something like this:
perl v5.12.5 Last change: 2012-11-03 2
Perl Programmers Reference Guide PERLAMIGA(1)
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.
Perl HTML Documentation on AmigaOS
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".
Perl GNU Info Files on AmigaOS
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.
Perl LaTeX Documentation on AmigaOS
Can be constructed using "pod2latex".
BUILDING PERL ON AMIGAOS
Here we discuss how to build Perl under AmigaOS.
Build Prerequisites for Perl on AmigaOS
You need to have the latest ixemul (Unix emulation for
Amiga) from Aminet.
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-$VERSION-src.tgz
perl v5.12.5 Last change: 2012-11-03 3
Perl Programmers Reference Guide PERLAMIGA(1)
or get the official source from CPAN:
http://www.cpan.org/src/5.0
Extract it like this
tar xvzpf perl-$VERSION.tar.gz
You will see a message about errors while extracting
Configure. This is normal and expected. (There is a conflict
with a similarly-named file configure, but it causes no
harm.)
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
Testing Perl on AmigaOS
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 on AmigaOS
Run
make install
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
perl v5.12.5 Last change: 2012-11-03 4
Perl Programmers Reference Guide PERLAMIGA(1)
backticks seems to generate nothing: very probably related
to the (v)fork problems. Fixing the breakage requires
someone quite familiar with the ixemul library, and how one
is supposed to run external commands in AmigaOS without
fork().
