HOWTO build zimlib for Symbian

Active Perl
5.6.1 or later, tested with 5.10.1.1007

http://www.activestate.com/activeperl/downloads/

S60 SDK
http://forum.nokia.com

Used: S60 3rd Edition SDK, FP1


 * http://sw.nokia.com/id/178ab2d1-b59d-4236-96e6-215ae212c223/S60-SDK-200634-3.1-Cpp-f.1090b.zip


 * newer should work, older versions won´t work for TODO application, while zimlb may work.

Also install arm tool chain, installer will ask you to do so

Carbide.c++
http://forum.nokia.com

Used version 2.3


 * http://sw.nokia.com/id/dcc2430b-57b4-4a66-ba07-1d8635691f3e/Carbide_cpp_v2_3_en.exe

QT
QT is not required for the zimib, but used in the TODO application

http://qt.nokia.com/downloads/symbian-cpp

Used QT libraries 4.6.2 for Symbian (LGPL)


 * http://get.qt.nokia.com/qt/source/qt-symbian-opensource-4.6.2.exe

Open C/C++ plug-in
http://forum.nokia.com

Used version 1.6


 * http://sw.nokia.com/id/fbe59b85-a621-404b-94d7-94ca818e576a/s60_open_c_cpp_plug_in_v1_6_en.zip

SVN client
Subclipse can be integrated in the Carbide.c++ IDE. For installation instructions have a look at:


 * http://wiki.forum.nokia.com/index.php/Using_Subclipse_with_Carbide.c%2B%2B

Alternatively for example tortoisesvn can be used:


 * http://tortoisesvn.net/downloads

e32def.h
Do the fix described in http://wiki.forum.nokia.com/index.php/KIS001022_-_Open_C:_Initializer_element_is_not_constant_error_on_GCCE_platform to the /Symbian/9.2/S60_3rd_FP1/EPOC32/include/e32def.h file.

Else libzma won´t compile. (/Symbian/9.2/S60_3rd_FP1/EPOC32/include/e32def.h:2803: error: initializer element is not constant).

Emulator
While not strictly necessary, I'd recommend to install the following patch. Without it I had problems running the emulator for the QT reader application.

http://wiki.forum.nokia.com/index.php/TSS000651_-_NCNList_KERN-EXEC_3_panic_when_starting_the_S60_3rd_Edition,_FP1_emulator

Install sources
First open Nokia/Carbide.c++ to create workpace

E.g. c:SymbianCarbideworkspace

Following description assumes that source is installed to subfolders in this workspace.

zimlib
See also RELEASES

Use svn to get zimlib source.

This howto assumes that you have zimlib directly in the carbide workspace. (And not for example zim/zimlib).

If you are using tortoisesve, right click on workspace folder in windows explorer, select 'SVN Checkout...' and put the following into URL of repository:


 * http://svn.openzim.org/svnroot/trunk/zimlib

Checkout directory should be automatically set to: c:SymbianCarbideworkspacezimlib

Note that zimreader and zimwriter are currently not supported on symbian. (And probably support does not make to much sense anyway).

liblzma
Used version:
 * http://tukaani.org/xz/xz-4.999.9beta.tar.gz

Extract to carbide workspace and rename folder to xz. (Carbide does not like the - in the folder name.)

There is also an embedded, more lightweight, version available, I have not tried that yet but may make sense to use it. However, also the regular version is running fine on the mobile phone.

libbz2
Used version:


 * http://www.bzip.org/1.0.5/bzip2-1.0.5.tar.gz

Extract to carbide workspace bzip2/src.

Port projects
Main porting effort is that symbian does not support autoconf.

Build configuration and config files
Symbian uses group/ .mmp and group/bld.inf to configure the build process.

Additionally for some of libraries (liblzma) config.h files, for unix builds generated with autoconfs have to be added.

Install buildfiles
Close Carbide.c++.

Extract buildandconfig.zip TODO to the workspace containing the libraries.

Open carbide.c++.

Select File/Import

Choose General/Existing Projects into Workspace

Select root directory: The workspace. (default C:SymbianCarbideworkspace)

Finish import.

Buildfile settings
The .mmp files defines - amongst others - the source files, include path, libraries, and target file.

bld.inf mainly serves to select the include files to be exported.

config.h settings
The config.h files have been generate in cygwin with autoconf and have been manually changed until build has been successul. Two changes worth to mention here: Bool type definition changed to int. Should be checked why necessary and whether safe. Change TODO
 * xz/symbian/config.h
 * zimlib/symbian/config.h

Source patches
Basically you can extract sourcepatches.zip into the workspace and overwrite existing files. However, this will cause problems if different versions of the library sources are used, therefore it is recommended to do the patches manually as described in the following sections.

Note, that the patches (TODO except PID?) should not break other target platforms and it would make sense to integrate them into the repositories.

_WIN32 defines
Some of the libs use _WIN32 to define some configurations. While this is not a problem for builds for the device, it causes problems in builds for the emulator, as it defines _WIN32 as well. Therefore the source files have to be changed so that in case __SYMBIAN32__ is defined _WIN32 is ignored. The following changes have to be done:

bzip2

 * bzip2/src/bzlib.h

Add

// Symbian compiler defines _WIN32 in builds for emulator. #undef _WIN32
 * 1) ifdef __SYMBIAN32__
 * 1) endif

before line
 * 1) ifdef _WIN32


 * bzip2/src/bzip2.c

add after


 * 1) define BZ_LCCWIN32 0


 * 1) if defined(_WIN32) && !defined(__CYGWIN__)&& !defined(__SYMBIAN32__)

liblzma

 * xzsrcliblzmaapilzma.h

Add // Symbian compiler defines _WIN32 in builds for emulator. #undef _WIN32
 * 1) ifdef __SYMBIAN32__
 * 1) endif

before


 * 1) ifndef LZMA_API_IMPORT


 * xzsrcliblzmacommoncommon.h

Only required if QT creator is used for building. For carbide it appearantly works without this patch: to and (strm)->allocator, __VA_ARGS__); to                        (strm)->allocator, variableargs);
 * 1) define lzma_next_strm_init(func, strm, ...)
 * 1) define lzma_next_strm_init(func, strm, variableargs...)

zimlib

 * zimlibincludezimzim.h

Add

// Symbian compiler defines _WIN32 in builds for emulator. #undef _WIN32
 * 1) ifdef __SYMBIAN32__
 * 1) endif

before


 * 1) ifdef _WIN32

zimlib

 * zimlibsrcuuid.cpp

add


 * 1) include 

If this is a problem for other builds a #ifdef __SYMBIAN32__ would have to be added additionally.

Build
With Project/Build All Configurations each of the projects can be built.

Build zimlib as last project.

Use
To use zimlib in a symbian project the following line have to be included into the projects mmp file:

SYSTEMINCLUDE  epoc32includestdapis SYSTEMINCLUDE  epoc32include SYSTEMINCLUDE  epoc32includestdapissys SYSTEMINCLUDE  epoc32includestdapisstlport

// Using main as entry point STATICLIBRARY  libcrt0.lib LIBRARY        libc.lib LIBRARY        euser.lib

LIBRARY libstdcpp.lib

STATICLIBRARY zimlib.lib STATICLIBRARY bzip2.lib STATICLIBRARY liblzma.lib LIBRARY libm.lib LIBRARY libz.lib

OPTION CW -wchar_t on

Additionally the heap and stacksize should be increased, for example by:

//Deault heapsize not large enough to decrypt lzma EPOCSTACKSIZE 0x10000 EPOCHEAPSIZE 0x5000 0x1000000

Install on phone
TODO qt sample app description still missing

Tested on N82. Should work on all S60 3rd edition FP1 (e.g. N95), and later. 5th edition (5800, N97) may work as well, but not tested.

Install QT
Install qt.sis from qt installation directory or TODO

Note: Project also build a sis with integrated	qt installer (TODO filename), using Nokia smart intaller, but installation did not work for me due to signing issue.
