PERLEPOC(1)						 Perl Programmers Reference Guide					       PERLEPOC(1)

NAME

       README.epoc - Perl for EPOC

SYNOPSIS

       Perl 5 README file for the EPOC Release 5 operating system.

INTRODUCTION

       EPOC is an OS for palmtops and mobile phones. For more informations look at: http://www.symbian.com/

       This is a port of perl to the epocemx SDK by Eberhard Mattes, which itself uses the SDK by symbian. Essentially epocemx it is a POSIX look
       alike environment for the EPOC OS. For more informations look at: http://www.windhager.de/~mattes/epocemx/

       perl and epocemx runs on Epoc Release 5 machines: Psion 5mx, 5mx Pro, Psion Revo, Psion Netbook and on the Ericson M128. It may run on Epoc
       Release 3 Hardware (Series 5 classic), too. For more information about this hardware please refer to http://www.psion.com/

       Vendors which like to have support for their devices are free to send me a sample.

INSTALLING PERL ON EPOC

       You can download a ready-to-install version from http://www.science-computing.de/o.flebbe/perl/

       You will need at least ~6MB free space in order to install and run perl.

       Please install the emxusr.sis package from http://www.windhager.de/~mattes/epocemx/ first.

       Install perl.sis on the EPOC machine. If you do not know how to do that, consult your PsiWin documentation.

       Perl itself and its standard library is using 4 MB disk space.  Unicode support and some other modules are left out. (For details, please
       look into epoc/createpkg.pl). If you like to use these modules, you are free to copy them from a current perl release.

STARTING PERL ON EPOC

       Please use the epocemx shell to start perl. perl integrates with the conventions of epocemx.

       Editors on Epoc

       A suitable text editor can be downloaded from symbian http://www.symbian.com/developer/downloads/files/editor.zip

       Features of Perl on Epoc

       The built-in function EPOC::getcwd returns the current directory.

       Restrictions of Perl on Epoc

       Features are left out, because of restrictions of the POSIX support in EPOC:

       o   socket IO is only implemented poorly. You can only use sysread and syswrite on them. The commands read, write, print, <> do not work
	   for sockets. This may change iff epocemx supports sockets.

       o   kill, alarm and signals. Do not try to use them. This may be impossible to implement on EPOC.

       o   select is missing.

       o   binmode does not exist. (No CR LF to LF translation for text files)

       o   EPOC does not handle the notion of current drive and current directory very well (i.e. not at all, but it tries hard to emulate one).
	   See PATH.

       o   Heap is limited to 4MB.

       o   Dynamic loading is not implemented.

       Compiling Perl 5 on the EPOC cross compiling environment

       Sorry, this is far too short.

       o   You will need the epocemx SDK from Eberhard Mattes.

       o   Get the Perl sources from your nearest CPAN site.

       o   Unpack the sources.

       o   Build a native perl from this sources... Make sure to save the miniperl executable as miniperl.native.

	   Start again from scratch

		 cp epoc/* .
		 ./Configure -S
		 make
		 cp miniperl.native miniperl
		 touch miniperl.exe
		 make
		 perl createpkg.pl

		 emxsis perl.pkg perl.sis

SUPPORT STATUS OF PERL ON EPOC

       I'm offering this port "as is". You can ask me questions, but I can't guarantee I'll be able to answer them. Since the port to epocemx is
       quite new, please check the web for updates first.

       Very special thanks to Eberhard Mattes for epocemx.
