7 README.epoc - Perl for EPOC
11 Perl 5 README file for the EPOC Release 5 operating system.
15 EPOC is an OS for palmtops and mobile phones. For more informations look at:
16 http://www.symbian.com/
18 This is a port of perl to the epocemx SDK by Eberhard Mattes, which
19 itself uses the SDK by symbian. Essentially epocemx it is a POSIX
20 look alike environment for the EPOC OS. For more informations look at:
21 http://www.windhager.de/~mattes/epocemx/
23 perl and epocemx runs on Epoc Release 5 machines: Psion 5mx, 5mx Pro,
24 Psion Revo, Psion Netbook and on the Ericson M128. It may run on Epoc
25 Release 3 Hardware (Series 5 classic), too. For more information about
26 this hardware please refer to http://www.psion.com/
28 Vendors which like to have support for their devices are free to send
31 =head1 INSTALLING PERL ON EPOC
33 You can download a ready-to-install version from
34 http://www.science-computing.de/o.flebbe/perl/
36 You will need at least ~6MB free space in order to install and run
39 Please install the emxusr.sis package from
40 http://www.windhager.de/~mattes/epocemx/ first.
42 Install perl.sis on the EPOC machine. If you do not know how to do
43 that, consult your PsiWin documentation.
45 Perl itself and its standard library is using 4 MB disk space.
46 Unicode support and some other modules are left out. (For details,
47 please look into epoc/createpkg.pl). If you like to use these modules,
48 you are free to copy them from a current perl release.
50 =head1 STARTING PERL ON EPOC
52 Please use the epocemx shell to start perl. perl integrates with the
53 conventions of epocemx.
55 =head2 Editors on Epoc
57 A suitable text editor can be downloaded from symbian
58 http://www.symbian.com/developer/downloads/files/editor.zip
60 =head2 Features of Perl on Epoc
62 The built-in function EPOC::getcwd returns the current directory.
64 =head2 Restrictions of Perl on Epoc
66 Features are left out, because of restrictions of the POSIX support in
73 socket IO is only implemented poorly. You can only use sysread and
74 syswrite on them. The commands read, write, print, <> do not work for
75 sockets. This may change iff epocemx supports sockets.
79 kill, alarm and signals. Do not try to use them. This may be
80 impossible to implement on EPOC.
88 binmode does not exist. (No CR LF to LF translation for text files)
92 EPOC does not handle the notion of current drive and current
93 directory very well (i.e. not at all, but it tries hard to emulate
98 Heap is limited to 4MB.
102 Dynamic loading is not implemented.
106 =head2 Compiling Perl 5 on the EPOC cross compiling environment
108 Sorry, this is far too short.
114 You will need the epocemx SDK from Eberhard Mattes.
118 Get the Perl sources from your nearest CPAN site.
126 Build a native perl from this sources... Make sure to save the
127 miniperl executable as miniperl.native.
129 Start again from scratch
134 cp miniperl.native miniperl
139 emxsis perl.pkg perl.sis
143 =head1 SUPPORT STATUS OF PERL ON EPOC
145 I'm offering this port "as is". You can ask me questions, but I can't
146 guarantee I'll be able to answer them. Since the port to epocemx is
147 quite new, please check the web for updates first.
149 Very special thanks to Eberhard Mattes for epocemx.
