NAMEperlamiga - Perl under Amiga OS
NOTEPerl 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 ``
SYNOPSISOne 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
A recent version of perl for the Amiga can be found at the Geek Gadgets section of the Aminet:
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
( <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 ofADE(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 AmigaOSStart 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 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
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 AmigaOSPerl under AmigaOS lacks some features of perl under
some features of the UNIXfilesystem 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
INSTALLATIONChange to the installation directory (most probably
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.
Manpages for Perl on AmigaOSIf 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
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
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 AmigaOSCan be constructed using "pod2latex".
BUILDING PERL ON AMIGAOSHere we discuss how to build Perl under AmigaOS.
Build Prerequisites for Perl on AmigaOSYou need to have the latest ixemul (Unix emulation for Amiga) from Aminet.
Getting the Perl Source for AmigaOSYou can either get the latest perl-for-amiga source from Ninemoons and extract it with:
tar xvzpf perl-$VERSION-src.tgz
or get the official source from
Extract it like this
tar xvzpf perl-$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 AmigaOSRemember to use a hefty wad of stack (I use 2000000)
sh configure.gnu --prefix=/gg
Testing Perl on AmigaOSNow run
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
