INSTALLING Qt Source Package Version %VERSION%. 1. If you have the commercial edition of Qt, install your license file as $HOME/.qt-license if you are on Unix. If you are on Windows, copy the license file into your home directory (this may be known as the userprofile environment variable) and rename it to .qt-license. For example on Windows XP, %USERPROFILE% should be something like C:\Documents and Settings\username. For the open source version you do not need a license file. 2. Unpack the archive if you have not done so already: On Unix (X11 and Mac): cd /tmp gunzip %DISTNAME%.tar.gz # uncompress the archive tar xvf %DISTNAME%.tar # unpack it This creates the directory /tmp/%DISTNAME% containing the files from the archive. We only support the GNU version of the tar archiving utility. Note that on some systems it is called gtar. On Windows, uncompress the files into the directory you want Qt installed, e.g. C:\Qt\%VERSION%. NOTE: The install path must not contain any spaces. 4. Environment variables In order to build and use Qt, the PATH environment variable needs to be extended to locate qmake, moc and other Qt tools On Windows, this is done by adding C:\Qt\%VERSION%\bin to the PATH variable. On Unix, this is done by adding /tmp/%DISTNAME%. For newer versions of Windows, PATH can be extended through "Control Panel->System->Advanced->Environment variables" and for older versions by editing C:\autoexec.bat. In .profile (if your Unix shell is bash), add the following lines: PATH=/usr/local/Trolltech/Qt-%VERSION%/bin:$PATH export PATH In .login (in case your Unix shell is csh or tcsh), add the following line: setenv PATH /usr/local/Trolltech/Qt-%VERSION%/bin:$PATH If you use a different Unix shell, please modify your environment variables accordingly. For some X11 compilers that do not support rpath you must also extended the LD_LIBRARY_PATH environment variable to include /usr/local/Trolltech/Qt-%VERSION%/lib. On Linux or Mac with GCC this step is not needed. 4. Building 4.1 Building on Unix To configure the Qt library for your machine type, run the ./configure script in the package directory. By default, Qt is configured for installation in the /usr/local/Trolltech/Qt-%VERSION% directory, but this can be changed by using the -prefix option. cd /tmp/%DISTNAME% ./configure Type "./configure -help" to get a list of all available options. To create the library and compile all the demos, examples, tools, and tutorials, type: make If you did not configure Qt using the -prefix-install option, you need to install the library, demos, examples, tools, and tutorials in the appropriate place. To do this, type: su -c "make install" and enter the root password. On some systems, you have to use the sudo command as follows: sudo make install and enter your password, this requires that you have administrator access to your machine. Note that on some systems the make utility is named differently, e.g. gmake. The configure script tells you which make utility to use. If you need to reconfigure and rebuild Qt from the same location, ensure that all traces of the previous configuration are removed by entering the build directory and typing make confclean before running the configure script again. 4.2 Building on Windows To configure the Qt library for your machine type: C: cd \Qt\%VERSION% configure Type "configure -help" to get a list of all available options. If you are using the "-direct3d" option, make sure that you have the Direct3D SDK installed, and that you have run the %DXSDK_DIR%\Utilities\Bin\dx_setenv.cmd command, before attempting to run configure. The actual commands needed to build Qt depends on your development system. For Microsoft Visual Studio to create the library and compile all the demos, examples, tools and tutorials type: nmake If you need to reconfigure and rebuild Qt from the same location, ensure that all traces of the previous configuration are removed by entering the build directory and typing nmake confclean before running the configure script again. 5. That's all. Qt is now installed. If you are new to Qt, we suggest that you take a look at the demos and examples to see Qt in action. Run the Qt Examples and Demos either by typing 'qtdemo' on the command line or through the desktop's Start menu.
