.SH "NAME"
README.symbian \- Perl version 5 on Symbian OS
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This document describes various features of the Symbian operating
system that will affect how Perl version 5 (hereafter just Perl)
is compiled and/or runs.
.PP
\&\fB\s-1NOTE:\s0 this port (as of 0.4.1) does not compile into a Symbian
\&\s-1OS\s0 \s-1GUI\s0 application, but instead it results in a Symbian \s-1DLL\s0.\fR
The \s-1DLL\s0 includes a \*(C+ class called CPerlBase, which one can then
(derive from and) use to embed Perl into applications, see \fIsymbian/README\fR.
.PP
The base port of Perl to Symbian only implements the basic POSIX-like
functionality; it does not implement any further Symbian or Series 60,
Series 80, or \s-1UIQ\s0 bindings for Perl.
.PP
It is also possible to generate Symbian executables for \*(L"miniperl\*(R"
and \*(L"perl\*(R", but since there is no standard command line interface
for Symbian (nor full keyboards in the devices), these are useful
mainly as demonstrations.
.Sh "Compiling Perl on Symbian"
.IX Subsection "Compiling Perl on Symbian"
(0) You need to have the appropriate Symbian \s-1SDK\s0 installed.
.PP
.Vb 5
\&    These instructions have been tested under various Nokia Series 60
\&    Symbian SDKs (1.2 to 2.6, 2.8 should also work, 1.2 compiles but
\&    does not work), Series 80 2.0, and Nokia 7710 (Series 90) SDK.
\&    You can get the SDKs from Forum Nokia (http://www.forum.nokia.com/).
\&    A very rough port ("it compiles") to UIQ 2.1 has also been made.
\&
\&    A prerequisite for any of the SDKs is to install ActivePerl
\&    from ActiveState, http://www.activestate.com/Products/ActivePerl/
\&
\&    Having the SDK installed also means that you need to have either
\&    the Metrowerks CodeWarrior installed (2.8 and 3.0 were used in testing)
\&    or the Microsoft Visual C++ 6.0 installed (SP3 minimum, SP5 recommended).
\&
\&    Note that for example the Series 60 2.0 VC SDK installation talks
\&    about ActivePerl build 518, which does no more (as of mid\-2005) exist
\&    at the ActiveState website.  The ActivePerl 5.8.4 build 810 was
\&    used successfully for compiling Perl on Symbian.  The 5.6.x ActivePerls
\&    do not work.
\&
\&    Other SDKs or compilers like Visual.NET, command\-line\-only
\&    Visual.NET, Borland, GnuPoc, or sdk2unix have not been tried.
\&
\&    These instructions almost certainly won\*(Aqt work with older Symbian
\&    releases or other SDKs.  Patches to get this port running in other
\&    releases, SDKs, compilers, platforms, or devices are naturally welcome.
.Ve
.PP
(1) Get a Perl source code distribution (for example the file
    perl\-5.9.2.tar.gz is fine) from http://www.cpan.org/src/
    and unpack it in your the C:/Symbian directory of your Windows
    system.
.PP
(2) Change to the perl source directory.
.PP
.Vb 1
\&        cd c:\eSymbian\eperl\-5.x.x
.Ve
.PP
(3) Run the following script using the perl coming with the \s-1SDK\s0
.PP
.Vb 1
\&        perl symbian\econfig.pl
\&
\&    You must use the cmd.exe, the Cygwin shell will not work.
\&    The PATH must include the SDK tools, including a Perl,
\&    which should be the case under cmd.exe.  If you do not
\&    have that, see the end of symbian\esdk.pl for notes of
\&    how your environment should be set up for Symbian compiles.
.Ve
.PP
(4) Build the project, either by
.PP
.Vb 1
\&        make all
\&
\&    in cmd.exe or by using either the Metrowerks CodeWarrior
\&    or the Visual C++ 6.0, or the Visual Studio 8 (the Visual C++
\&    2005 Express Edition works fine).
\&
\&    If you use the VC IDE, you will have to run F<symbian\econfig.pl>
\&    first using the cmd.exe, and then run \*(Aqmake win.mf vc6.mf\*(Aq to generate
\&    the VC6 makefiles and workspaces.  "make vc6" will compile for the VC6,
\&    and "make cw" for the CodeWarrior.
\&
\&    The following SDK and compiler configurations and Nokia phones were
\&    tested at some point in time (+ = compiled and PerlApp run, \- = not),
\&    both for Perl 5.8.x and 5.9.x:
\&
\&        SDK     | VC | CW |
\&        \-\-\-\-\-\-\-\-+\-\-\-\-+\-\-\-\-+\-\-\-
\&        S60 1.2 | +  | +  | 3650 (*)
\&        S60 2.0 | +  | +  | 6600
\&        S60 2.1 | \-  | +  | 6670
\&        S60 2.6 | +  | +  | 6630    
\&        S60 2.8 | +  | +  | (not tested in a device)
\&        S80 2.6 | \-  | +  | 9300
\&        S90 1.1 | +  | \-  | 7710
\&        UIQ 2.1 | \-  | +  | (not tested in a device)
\&
\&    (*) Compiles but does not work, unfortunately, a problem with Symbian.
\&
\&    If you are using the \*(Aqmake\*(Aq directly, it is the GNU make from the SDKs,
\&    and it will invoke the right make commands for the Windows emulator
\&    build and the Arm target builds (\*(Aqthumb\*(Aq by default) as necessary.
\&
\&    The build scripts assume the \*(Aqabsolute style\*(Aq SDK installs under C:,
\&    the \*(Aqsubst style\*(Aq will not work.
\&
\&    If using the VC IDE, to build use for example the File\->Open Workspace\->
\&    C:\eSymbian\e8.0a\eS60_2nd_FP2\eepoc32\ebuild\esymbian\eperl\eperl\ewins\eperl.dsw
\&    The emulator binaries will appear in the same directory.
\&
\&    If using the VC IDE, you will a lot of warnings in the beginning of
\&    the build because a lot of headers mentioned by the source cannot
\&    be found, but this is not serious since those headers are not used.
\&
\&    The Metrowerks will give a lot of warnings about unused variables and
\&    empty declarations, you can ignore those.
\&
\&    When the Windows and Arm DLLs are built do not be scared by a very long
\&    messages whizzing by: it is the "export freeze" phase where the whole
\&    (rather large) API of Perl is listed.
\&
\&    Once the build is completed you need to create the DLL SIS file by
\&
\&        make perldll.sis
\&
\&    which will create the file perlXYZ.sis (the XYZ being the Perl version)
\&    which you can then install into your Symbian device: an easy way
\&    to do this is to send them via Bluetooth or infrared and just open
\&    the messages.
\&
\&    Since the total size of all Perl SIS files once installed is
\&    over 2 MB, it is recommended to do the installation into a
\&    memory card (drive E:) instead of the C: drive.
\&
\&    The size of the perlXYZ.SIS is about 370 kB but once it is in the
