NAME
perlamiga - Perl under Amiga OSSYNOPSIS
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:
http://www.aminet.net/~aminet/dirs/dev_gg.html
DESCRIPTION
Prerequisites
- 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-binNote 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
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.)
Shortcomings of Perl under AmigaOS
Perl under AmigaOS lacks some features of perl under UNIX because of deficiencies 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 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
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
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.
HTML
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".
GNU info files
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.LaTeX docs
can be constructed using "pod2latex".BUILD
Here we discuss how to build Perl under AmigaOS.Prerequisites
You need to have the latest ixemul (Unix emulation for Amiga) from Aminet.Getting the perl source
You can either get the latest perl-for-amiga source from Ninemoons and extract it with:
tar xvzpf perl-$VERSION-src.tgzor get the official source from CPAN:
http://www.perl.com/CPAN/src/5.0Extract it like this
tar xvzpf perl-$VERSION.tar.gzYou 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
- *
- remember to use a healthy sized stack (I used 2000000)
- *
- your PATH environment variable must include /bin (e.g. ``.:/bin'' is good) (or, more precisely, it must include the directory where you have your basic UNIX utilities like test, cat, sed, and so on)
- *
-
sh Configure -Dprefix=/ade -Dloclibpth=/ade/lib
- *
-
fix makedepend
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. - *
-
now type make depend
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.... - *
-
now go to the x2p directory
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.... - *
-
Now!
make
Testing
Now run
make testSome 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
Run
make install
