perlamiga - Perl under Amiga OS
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 as is: either as README.amiga, or pod/perlamiga.pod.
A recent version of perl for the Amiga can be found at the Geek Gadgets section of the Aminet:
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).
You need at the very least AmigaOS version 2.0. Recommended is version 3.1.
Start 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 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.)
Perl under AmigaOS lacks some features of perl under UNIX because of deficiencies in the UNIX-emulation, most notably:
Change to the installation directory (most probably ADE:), and extract 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.
If 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.
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
Emacs would appreciate it very much, especially with
CPerl mode loaded. You need to get latest
CPAN, or, alternately, prebuilt info pages.
can be constructed using
Here we discuss how to build Perl under AmigaOS.
You need to have the latest ixemul (Unix emulation for Amiga) from Aminet.
You can either get the latest perl-for-amiga source from Ninemoons and extract it with:
tar xvzpf perl-$VERSION-src.tgz
or get the official source from CPAN:
Extract it like this
tar xvzpf perl-$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.)
sh Configure -Dprefix=/ade -Dloclibpth=/ade/lib
In the file 'makedepend' there are three spots like this `$cat ...`: a for loop near line 75, an egrep near line 161, and a for loop near line 175. In all those spots using an editor change the $cat to /bin/cat.
When the make depend has ended load the gnumakefile into an editor and go to the end of the file. Move upwards in the file until you reach av.o: EXTERN.h and delete all lines down to # WARNING: Put....
Load the gnumakefile into an editor. Go to the end moveup until you reach hash.o: EXTERN.h and delete all lines dowonwards until you reach a line saying # WARNING: Put nothing....
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
