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.
IINNTTRROODDUUCCTTIIOONN
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 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 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.

You can download a ready-to-install version from
http://www.oflebbe.de/oflebbe/perl/
You will need at least ~6MB free space in order to install and run
perl.
Please install the emxusr.sis package from http://epocemx.source-
forge.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.

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

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

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

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 impos-
sible 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 direc-
tory 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.

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

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.
