perlamiga - Perl under Amiga OS
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 README.amiga, or pod/perlamiga.pod.
DESCRIPTIONPrerequisites 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 following archives from ftp://ftp.ninemoons.com/pub/ade/current or a mirror: ixemul-46.0-bin.lha ixemul-46.0-env-bin.lha pdksh- 4.9-bin.lha ADE-misc-bin.lha Note that there might be newer versions available by the time you read this. 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 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() file dates some features of the UNIX filesystem regarding link count and inplace operation (the -i switch) without backup file file is finally close()d umask() works, but the correct permissions are only set when the
INSTALLATIONChange to the installation directory (most probably ADE:), and extract the binary distribution: lha -mraxe x perl-5.003-bin.lha or tar xvzpf perl-5.003-bin.tgz (Of course you need lha or tar and gunzip for this.) For installation of the Unix emulation, read the appropriate docs.
Accessing documentationManpages 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'.
BUILDHere we discuss how to build Perl under AmigaOS. Prerequisites You need to have the latest ADE (Amiga Developers Environment) from ftp://ftp.ninemoons.com/pub/ade/current. Also, you need a lot of free memory, probably at least 8MB. Getting the perl source You can either get the latest perl-for-amiga source from Ninemoons and extract it with: tar xvzpf perl-5.004-src.tgz or get the official source from CPAN: http://www.perl.com/CPAN/src/5.0 Extract it like this tar xvzpf perl5.004.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 sh configure.gnu --prefix=/ade Now make Testing 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 Run make install
