If you read this file _as_is_, just ignore the funny characters you see. It is written in the POD format (see pod/perlpod.pod) which is specially designed to be readable as is. =head1 NAME perlepoc - Perl for EPOC =head1 SYNOPSIS Perl 5 README file for the EPOC Release 5 operating system. =head1 INTRODUCTION EPOC is an OS for palmtops and mobile phones. For more information look at: L<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 information look at: L<http://epocemx.sourceforge.net/> perl and epocemx runs on Epoc Release 5 machines: Psion 5mx, 5mx Pro, Psion Revo, Psion Netbook and on the Ericsson M128. It may run on Epoc Release 3 Hardware (Series 5 classic), too. For more information about this hardware please refer to L<http://www.psion.com/> Vendors which like to have support for their devices are free to send me a sample. =head1 INSTALLING PERL ON EPOC You can download a ready-to-install version from L<http://www.oflebbe.de/perl/perl5.html> You will need at least ~6MB free space in order to install and run perl. Please install the emxusr.sis package from L<http://epocemx.sourceforge.net/> 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. =head1 STARTING PERL ON EPOC Please use the epocemx shell to start perl. perl integrates with the conventions of epocemx. =head2 Features of Perl on Epoc The built-in function EPOC::getcwd returns the current directory. =head2 Restrictions of Perl on Epoc Features are left out, because of restrictions of the POSIX support in EPOC: =over 4 =item * 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. =item * kill, alarm and signals. Do not try to use them. This may be impossible to implement on EPOC. =item * select is missing. =item * binmode does not exist. (No CR LF to LF translation for text files) =item * 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. =item * Heap is limited to 4MB. =item * Dynamic loading is not implemented. =back =head2 Compiling Perl 5 on the EPOC cross compiling environment Sorry, this is far too short. =over 4 =item * You will need the epocemx SDK from Eberhard Mattes. =item * Get the Perl sources from your nearest CPAN site. =item * Unpack the sources. =item * 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 =back =head1 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. =head1 AUTHOR Olaf Flebbe <olaf@oflebbe.de> L<http://www.oflebbe.de/perl/perl5.html> =head1 LAST UPDATE 2003-01-18 =cut
