|

| 10 |
|
|---|
| 11 | Perl 5 README file for the EPOC Release 5 operating system.
|
|---|
| 12 |
|
|---|
| 13 | =head1 INTRODUCTION
|
|---|
| 14 |
|
|---|
| 15 | EPOC is an OS for palmtops and mobile phones. For more informations look at:
|
|---|
| 16 | http://www.symbian.com/
|
|---|
| 17 |
|
|---|
| 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 information look at:
|
|---|
| 21 | http://epocemx.sourceforge.net/
|
|---|
| 22 |
|
|---|
| 23 | perl and epocemx runs on Epoc Release 5 machines: Psion 5mx, 5mx Pro,
|
|---|
| 24 | Psion Revo, Psion Netbook and on the Ericsson 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/
|
|---|
| 27 |
|
|---|
| 28 | Vendors which like to have support for their devices are free to send
|
|---|
| 29 | me a sample.
|

| 31 | =head1 INSTALLING PERL ON EPOC
|
|---|
| 32 |
|
|---|
| 33 | You can download a ready-to-install version from
|
|---|
| 34 | http://www.oflebbe.de/oflebbe/perl/
|
|---|
| 35 |
|
|---|
| 36 | You will need at least ~6MB free space in order to install and run perl.
|
|---|
| 37 |
|
|---|
| 38 | Please install the emxusr.sis package from
|
|---|
| 39 | http://epocemx.sourceforge.net/ first.
|
|---|
| 40 |
|
|---|
| 41 | Install perl.sis on the EPOC machine. If you do not know how to do
|
|---|
| 42 | that, consult your PsiWin documentation.
|
|---|
| 43 |
|
|---|
| 44 | Perl itself and its standard library is using 4 MB disk space.
|
|---|
| 45 | Unicode support and some other modules are left out. (For details,
|
|---|
| 46 | please look into epoc/createpkg.pl). If you like to use these modules,
|
|---|
| 47 | you are free to copy them from a current perl release.
|
|---|
| 48 |
|
|---|
| 49 | =head1 STARTING PERL ON EPOC
|
|---|
| 50 |
|
|---|
| 51 | Please use the epocemx shell to start perl. perl integrates with the
|
|---|
| 52 | conventions of epocemx.
|
|---|
| 53 |
|
|---|
| 54 | =head2 Editors on Epoc
|
|---|
| 55 |
|
|---|
| 56 | A suitable text editor can be downloaded from symbian
|
|---|
| 57 | http://www.symbian.com/developer/downloads/files/editor.zip
|
|---|

|
|---|
| 59 | =head2 Features of Perl on Epoc
|
|---|
| 60 |
|
|---|
| 61 | The built-in function EPOC::getcwd returns the current directory.
|
|---|
| 62 |
|
|---|
| 63 | =head2 Restrictions of Perl on Epoc
|
|---|
| 64 |
|
|---|
| 65 | Features are left out, because of restrictions of the POSIX support in
|
|---|
| 66 | EPOC:

|

| 71 |
|
|---|
| 72 | socket IO is only implemented poorly. You can only use sysread and
|
|---|
| 73 | syswrite on them. The commands read, write, print, <> do not work for
|
|---|
| 74 | sockets. This may change iff epocemx supports sockets.

|

|

|

| 79 | impossible to implement on EPOC.

|

| 92 | directory very well (i.e. not at all, but it tries hard to emulate
|
|---|
| 93 | one). See PATH.

|

| 143 |
|
|---|
| 144 | I'm offering this port "as is". You can ask me questions, but I can't
|
|---|
| 145 | guarantee I'll be able to answer them. Since the port to epocemx is
|
|---|
| 146 | quite new, please check the web for updates first.
|
|---|
| 147 |
|
|---|
| 148 | Very special thanks to Eberhard Mattes for epocemx.
