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

Please install the emxusr.sis package from 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.

*

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.

*

kill, alarm and signals. Do not try to use them. This may be impossible 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 current directory very well (i.e. not at all, but it tries hard to emulate one). See PATH.

*

Heap is limited to 4MB.

*

Dynamic loading is not implemented.

Compiling Perl 5 on the EPOC cross compiling environment

*

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 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

Very special thanks to Eberhard Mattes for epocemx.
