Qt for Symbian binaries can be downloaded directly so development of applications using Qt for Symbian can start right away. Step 1: Setup the Development EnvironmentQt for the Symbian platform has some requirements on the development platform. The Symbian SDK for Linux as well as a cross compiler for the ARM processor used on Symbian devices should be present on the development machine. See http://qt.gitorious.org/qt/pages/QtCreatorSymbianLinux for more details. Step 2: Unpack the ArchiveUncompress the downloaded source package into the directory you want Qt installed, e.g. /home/user/qt/4.7. Step 3: Set the Environment VariablesIn order to build and use Qt, the PATH environment variable needs to be extended to fine Qt tools and also to find the Symbian platform tools: First you need to set the EPOCROOT environment variable to point to the location of your S60 SDK: EPOCROOT=/home/user/s60-sdk/ export EPOCROOT Then you can update the PATH variable; PATH=/home/user/qt/4.7/bin:$EPOCROOT/epoc32/tools:$PATH export PATH Step 4: Configure QtTo configure Qt for the Symbian platform, do: cd /home/user/qt/4.7 ./configure -platform linux-g++ -xplatform symbian-armcc to build the libraries using RVCT or cd /home/user/qt/4.7 ./configure -platform linux-g++ -xplatform symbian-gcce -no-webkit to build the libraries using GCCE. Type ./configure -help to get a list of all available options. The Configuration Options for Qt page gives a brief overview of these. Step 5: Build QtTo build Qt for the device, type: make Congratulations, Qt is now ready to use. Step 6: Building Qt Packages for the DeviceTo run any application or demo on a real device, you need to install it on the device. To do this you first have to create a a package for the device, containing the libraries: Building a Qt package without a certificate If you have no certificate, build a self signed Qt: cd src make sis The Qt libraries are built with "All -Tcb" capability, so that they can support all types of applications. However, these capabilities are automatically lowered if you make a self-signed package. Building a Qt package with a Symbian developer certificate If you have a Symbian-signed developer certificate, specify the capabilities you can sign for, for example: cd src/s60installs patch_capabilities.pl Qt_template.pkg - "ALL -Tcb -AllFiles -DRM" make sis QT_SIS_CERTIFICATE=<certificate file> QT_SIS_KEY=<certificate key file> cd ../3rdparty/webkit/WebCore patch_capabilities.pl QtWebKit_template.pkg - "ALL -Tcb -AllFiles -DRM" make sis QT_SIS_CERTIFICATE=<certificate file> QT_SIS_KEY=<certificate key file> Installing Qt Packages to the Device.It is possible to install packages to a phone in Linux by putting the package on the phone memory card and then installing manually from the phone menu. However, this is tedious and will not work on phones without a memory card, so the method recommended by Qt is to use the App TRK tool. Obtaining the App TRK package.Download the package from the following location.
This package currently has to be installed by putting the package on the memory card and installing from the phone menu, or using a Windows PC for doing the install. However, the installation only has to be done once. Configuring App TRK on the PhoneWhen 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. Configuring the USB Serial Driver on the Linux SystemOn 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: lsusb 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. sudo rmmod usbserial sudo modprobe usbserial vendor=0x0XXX product=0x0XXX The rmmod step may fail if the module is not already loaded, but that is harmless. Building the runonphone Tool.Note that building the runonphone tool requires a separate installation of Qt for Linux. If there is a version of Qt installed by your distribution's package mechanism, that that should do fine. Some distributions separate the libraries from the development setup which includes qmake. Make sure you have both installed. You will also need the libusb libraries and header files installed. Usually, installing a development package such as libusb-dev will ensure that you have all the necessary dependencies installed. First, make sure that the qmake you use is taken from the Linux installation of Qt. The easiest way to make sure of this is to open a new shell and run the following command: $ qmake -version QMake version 2.01a Using Qt version 4.6.2 in /usr/lib/qt4 qmake will tell you where it is installed. Copy the %QTDIR%/tools/runonphone folder to a place outside of the Qt tree. Then go to the folder in a shell and build it: cd $HOME/runonphone qmake make Copy the resulting executable to a folder which is in your PATH environment variable. Installing the Built Package onto the PhoneNote: Before starting, please make sure that there is no previously installed version of Qt on the phone. Return to the root of the Qt tree configured for Symbian. Then install the Qt libraries by running the following: runonphone -s lib/Qt.sis You may need to supply the path of the serial device file using the -p option: runonphone -s lib/Qt.sis -p /dev/ttyUSB1 If the installation fails, please make sure that there is no previously installed version of Qt on the phone. Qt requires some dependent packages to be installed on the device, which can be installed using the runonphone tool as well. One is the sqlite3.sis, which is included in the Qt distribution, while the others are shipped with the Symbian SDK. The required packages can be found from the following locations: src/s60installs/sqlite3.sis $EPOCROOT/nokia_plugin/openc/s60opencsis/openc_ssl_s60_1_6_ss.sis $EPOCROOT/nokia_plugin/openc/s60opencsis/pips_s60_1_6_ss.sis $EPOCROOT/nokia_plugin/opencpp/s60opencppsis/stdcpp_s60_1_6_ss.sis It is also possible to install packages onto the device using the runonphone build rule that qmake automatically generates for each Qt project. Options can be supplied to the runonphone tool that is invoked begind the scenes: make runonphone "QT_RUN_ON_PHONE_OPTIONS=-p /dev/ttyUSB1" If you are running runonphone or invoking the runonphone build rule often, it is possible to set the QT_RUN_ON_PHONE_OPTIONS environment variable with the options you normally use: export QT_RUN_ON_PHONE_OPTIONS="-p /dev/ttyUSB1" make runonphone This makes installation of packages onto a device easier and less error-prone. Running Qt DemosWe've included a subset of the Qt demos in this package for you to try out. An excellent starting point is the "fluidlauncher" demo. Install and run the demo by using the following commands: cd demos/embedded/fluidlauncher runonphone -s fluidlauncher.sis fluidlauncher.exe The same command can be used for other applications: cd myapp qmake make make sis runonphone -s myapp.sis myapp.exe For more information about building and running Qt programs on the Symbian platform, see The Symbian platform - Introduction to Qt. We hope you will enjoy using Qt. |
