- =head1 NAME
-
- README.epoc - 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 informations look at:
- http://www.symbian.com/
-
- This is a port of perl to the epocemx SDK by Eberhard Mattes, which
- itselfs 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.
-
- =head1 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.
-
- =head1 STARTING PERL ON EPOC
-
- Please use the epocemx shell to start perl. perl integrates with the
- conventions of epocemx.
-
- =head2 Editors on Epoc
-
- A suitable text editor can be downloaded from symbian
- http://www.symbian.com/developer/downloads/files/editor.zip
-
- =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.
-

-
- =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

-
- =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.
