9 Perl 5 README file for the EPOC Release 5 operating system.
10
12 EPOC is an OS for palmtops and mobile phones. For more informations
13 look at: http://www.symbian.com/
14 This is a port of perl to the epocemx SDK by Eberhard Mattes, which
16 itself uses the SDK by symbian. Essentially epocemx it is a POSIX look
17 alike environment for the EPOC OS. For more information look at:
18 http://epocemx.sourceforge.net/
19 perl and epocemx runs on Epoc Release 5 machines: Psion 5mx, 5mx Pro,
21 Psion Revo, Psion Netbook and on the Ericsson M128. It may run on Epoc
22 Release 3 Hardware (Series 5 classic), too. For more information about
23 this hardware please refer to http://www.psion.com/
24 Vendors which like to have support for their devices are free to send
26 me a sample.

29 You can download a ready-to-install version from
30 http://www.oflebbe.de/oflebbe/perl/
31 You will need at least ~6MB free space in order to install and run
33 perl.
34 Please install the emxusr.sis package from http://epocemx.source‐
36 forge.net/ first.
37 Install perl.sis on the EPOC machine. If you do not know how to do
39 that, consult your PsiWin documentation.
40 Perl itself and its standard library is using 4 MB disk space. Unicode
42 support and some other modules are left out. (For details, please look
43 into epoc/createpkg.pl). If you like to use these modules, you are free
44 to copy them from a current perl release.
45
47 Please use the epocemx shell to start perl. perl integrates with the
48 conventions of epocemx.
49 Editors on Epoc
51 A suitable text editor can be downloaded from symbian http://www.sym‐
53 bian.com/developer/downloads/files/editor.zip
54 Features of Perl on Epoc
56 The built-in function EPOC::getcwd returns the current directory.
58 Restrictions of Perl on Epoc
60 Features are left out, because of restrictions of the POSIX support in
62 EPOC:
63 · socket IO is only implemented poorly. You can only use sysread and
65 syswrite on them. The commands read, write, print, <> do not work
66 for sockets. This may change iff epocemx supports sockets.
67 · kill, alarm and signals. Do not try to use them. This may be impos‐
69 sible to implement on EPOC.
70 · select is missing.
72 · binmode does not exist. (No CR LF to LF translation for text files)
74 · EPOC does not handle the notion of current drive and current direc‐
76 tory very well (i.e. not at all, but it tries hard to emulate one).
77 See PATH.
78 · Heap is limited to 4MB.
80 · Dynamic loading is not implemented.
82 Compiling Perl 5 on the EPOC cross compiling environment
84 Sorry, this is far too short.
86 · You will need the epocemx SDK from Eberhard Mattes.
88 · Get the Perl sources from your nearest CPAN site.
90 · Unpack the sources.
92 · Build a native perl from this sources... Make sure to save the
94 miniperl executable as miniperl.native.
95 Start again from scratch
97 cp epoc/* .
99 ./Configure -S
100 make
101 cp miniperl.native miniperl
102 touch miniperl.exe
103 make
104 perl createpkg.pl
105 emxsis perl.pkg perl.sis
107
109 I'm offering this port "as is". You can ask me questions, but I can't
110 guarantee I'll be able to answer them. Since the port to epocemx is
111 quite new, please check the web for updates first.
112 Very special thanks to Eberhard Mattes for epocemx.
