Perl 5.8.0 cannot be built in AmigaOS. You can use either themaintenance release Perl 5.6.1 or the development release Perl 5.7.2in AmigaOS. See PERL 5.8.0 BROKEN IN AMIGAOS if you want to helpfixing this problem.

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 maybe read as is: either as README.amiga, or pod/perlamiga.pod.

A recent version of perl for the Amiga can be found at the Geek Gadgetssection of the Aminet:

  http://www.aminet.net/~aminet/dev/gg

DESCRIPTION

Prerequisites for Compiling Perl on AmigaOS

Unix emulation for AmigaOS: ixemul.library
You need the Unix emulation for AmigaOS, whose most important part isixemul.library. For a minimum setup, get the latest versionsof 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 otherpackages 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 thesame 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 (asopposed to your program), use

perl -my_opts foo arg1 arg2 arg3

Alternately, you can try to get a replacement for the system's Executecommand that honors the #!/usr/bin/perl syntax in scripts and set the s-Bitof 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 notnecessary, perl would be enough, but having full path would make iteasier to use your script under *nix.)

Shortcomings of Perl under AmigaOS

Perl under AmigaOS lacks some features of perl under UNIX because ofdeficiencies 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 isfinally close()d

INSTALLATION

Change to the installation directory (most probably ADE:), andextract the binary distribution:

lha -mraxe x perl-$VERSION-bin.lha

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 perlmanpages, 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 manpagesin the /ade/lib/perl5/man/man3 directory, or the man pages for theperl library will not be found.

Note that dot (.) is used as a package separator for documentationfor packages, and as usual, sometimes you need to give the section - 3above - 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 thisdirectory, 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 withCPerl 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 Ninemoonsand 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 Configure. Thisis normal and expected. (There is a conflict with a similarly-named fileconfigure, 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 filepod/perlhack.pod for how to get the individual changes) Perl droppedits internal support for vfork(), and that was very probably the stepthat broke AmigaOS (since the ixemul library has only vfork). The build finally fails when the ext/DynaLoader is being built, andPERL ends up as "0" in the produced Makefile, trying to run "0" doesnot quite work. Also, executing miniperl in backticks seems togenerate nothing: very probably related to the (v)fork problems.Fixing the breakage requires someone quite familiar with the ixemullibrary, and how one is supposed to run external commands in AmigaOSwithout fork().
