PERLAMIGA !!!PERLAMIGA NAME SYNOPSIS DESCRIPTION INSTALLATION Accessing documentation BUILD AUTHORS SEE ALSO ---- !!NAME perlamiga - Perl under Amiga OS !!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 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-bin 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()'' 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-$VERSION-src.tgz or get the official source from CPAN: http://www.perl.com/CPAN/src/5.0 Extract it like this tar xvzpf perl-$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__ 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 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 !!AUTHORS Norbert Pueschel, pueschel@imsdd.meb.uni-bonn.de Jan-Erik Karlsson, trg@privat.utfors.se !!SEE ALSO perl(1). ----
