NAME

perlepoc - 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 information lookat: http://www.symbian.com/

This is a port of perl to the epocemx SDK by Eberhard Mattes, whichitself uses the SDK by symbian. Essentially epocemx it is a POSIXlook alike environment for the EPOC OS. For more information look at: 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 EpocRelease 3 Hardware (Series 5 classic), too. For more information aboutthis hardware please refer to http://www.psion.com/

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

INSTALLING PERL ON EPOC

You can download a ready-to-install version fromhttp://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 fromhttp://epocemx.sourceforge.net/ first.

Install perl.sis on the EPOC machine. If you do not know how to dothat, 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 theconventions of epocemx.

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 inEPOC:

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

• kill, alarm and signals. Do not try to use them. This may beimpossible to implement on EPOC.

• select is missing.

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

• EPOC does not handle the notion of current drive and currentdirectory very well (i.e. not at all, but it tries hard to emulateone). See PATH.

• Heap is limited to 4MB.

• Dynamic loading is not implemented.

Compiling Perl 5 on the EPOC cross compiling environment

Sorry, this is far too short.

• You will need the epocemx SDK from Eberhard Mattes.

• Get the Perl sources from your nearest CPAN site.

• Unpack the sources.

• Build a native perl from this sources... Make sure to save theminiperl 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'tguarantee I'll be able to answer them. Since the port to epocemx isquite new, please check the web for updates first.

Very special thanks to Eberhard Mattes for epocemx.
