This article borrows hugely from: http://labs.qt.nokia.com/2010/12/17/experimental-packages-for-symbian-development-on-linux/

First, there’s Qt SDK and Nokia Qt SDK. In a word, Qt SDK is for desktop development, while Nokia Qt SDK is for mobile development. A detailed comparison can be found here.

Then, there’s S60 SDK. Is it necessary to install it before developing symbian applications? The S60 SDK is only available under Windows platform. Under Windows, Nokia Qt SDK is an all-in-one package. It includes S60 SDK, Qt SDK, QtSimulator and a Symbian compiler. So, the AIO package is recommended. There’s another choice under Windows: S60 SDK + Qt for Symbian. The Symbian version can be found here. But this time, there’s no simulator.

As mentioned here, These two SDK will be merged in Nokia Qt SDK 1.1.

Now, we will have our Linux tutorial for Ubuntu.

1. Download and install the following packages (32-bit versions only):
* gcce-4.4.172-r1.deb
* s60-sdk-5.0.deb
* runonphone-4.7.1.deb
* qt-symbian-libs-4.7.1-r1.deb (Old version: qt-symbian-libs-4.7.1.deb)

2. Install App TRK on your phone. It’s a debug service. Find *.sisx files here. Check the TRKPackages.xml file to get correct version for your phone. For my C5-03, I used s60_5_0_app_trk_3_2_7.sisx.

3. Install Qt libs for Symbian. They can be found at Qt’s ftp site: ftp://ftp.qt.nokia.com/pub/qt/symbian/. I installed version 4.7.1 as the developing library. Here’s what exactly each *.sis package contains:

* fluidlauncher.sis
Contains around 10 different Qt demos. Depends on Qt and Open C.
* qt.sis
Contains the Qt libraries Symbian Signed for Nokia phones. Depends on Open C.
* qt_selfsigned.sis
A self-signed version of the above library. Works on other phones such as the Samsung i8910.
* qtwebkit.sis
Contains the QtWebKit library Symbian Signed for Nokia phones. Depends on Qt.
* qtwebkit_selfsigned.sis
A self-signed version of the above library. Works on other phones such as the Samsung i8910.
* qt_demos.sis
Contains qt.sis, qtwebkit.sis, fluidlauncher.sis and Open C all in one convenient package. No other dependencies.
* qt_installer.sis
Contains qt.sis, qtwebkit.sis and Open C all in one convenient package. No other dependencies.

Installing qt_installer.sis is enough.

4. Configure your QtCreator, add QtSimulator and QtSymbian versions. The Qt4 page should be something like:

qt_symbian_1

5. Now, create a simple GUI application and add desktop/simulator/device targets, so that you can run on all of them.
qt_symbian_2

6. Run on phone.

When App TRK is installed, connect the phone to the PC using the USB cable. Select “PCSuite” as connection type. Then run App TRK on the phone, and make sure that the connection type is USB. This can be changed under the Settings menu entry. If necessary, choose Connect from the menu.

On Linux, phone should appear as the /dev/ttyUSB1 device, however if you are running an old kernel, you may need to force the USB module to be loaded correctly before the device will appear:

Note the identifier on the line where your Symbian device appears. Then execute the following, using the first and second part of the identifier in place of XXX, respectively.

For my C5-03, It’s:

The rmmod step may fail if the module is not already loaded, but that is harmless.

In QtCreator, go to Projects –> Targets –> Symbian Device, refresh the serial port, select USB1 and connect to your phone.

qt_symbian_3

Congratulations! you’ve done. Select Symbian device as your target and click run button. This will package, deploy and run your application on your phone. Simple, Huhhh?

    This article applies to Ubuntu 8.04/10.04. I referred to the instruction here: http://ubuntuforums.org/showthread.php?t=51003. And I’ll use my qastrologer project to demo the building procedure.

1. Install build tool packages:

2. Get the source package, exact it into ~/packages/qastrologer. The directory structure should like: ~/packages/qastrologer/qastrologer-<version>/<source>. The <source> directory contains your *.pro file.

3. Add install section in *.pro file. Otherwise, the built package contains not binary:

I referred to the guild here: http://wiki.maemo.org/Packaging_a_Qt_application. For more information on how to use the INSTALLS macro, refer to the Qt document: http://doc.trolltech.com/4.7/qmake-environment-reference.html#installs

4. Run dh_make. This will create the basic debian package structure.

We are generating a single binary package and licensed with GPL. After running the command, a “debian” subdirectory is created. Now we need to fill in more useful infomations.

5. “rules” file:

It is the most important build script. The cdbs already have support for building QMake projects. Our “rules” file is simple:

Last line ensures we use Qt4. I referred to the source of minitube project. You can access it via:

6. “control” file:

This file controls build and binary dependency. For my qastrologer, the default values are enough. You may want to have some minor changes in “Section”/”Priority”/”Maintainer” values. Since I want to keep my package installs from 8.04 to 10.04 and above, I must specify the minimum dependencies manually to use Qt 4.3. So my “control” file looks like:

Note, the default “control” file uses “${shlibs:Depends}” and “${misc:Depends}” macros to generate binary dependencies automatically. Refer to the man page of debhelper to get more information.

7. Fill in “changelog” and “copyright” files.

8. Build the package:

For full build of the package (build source, deb, clean…) run:

Instead if you have a big package, you can also build only the deb file with:
