INSTALLING Qt/X11 Version 4.1.3. 1. If you have the commercial edition of Qt, install your license file as $HOME/.qt-license. For the open source version you do not need a license file. 2. Unpack the archive if you have not done so already: cd /tmp gunzip qt-x11-opensource-src-4.1.3.tar.gz # uncompress the archive tar xvf qt-x11-opensource-src-4.1.3.tar # unpack it This creates the directory /tmp/qt-x11-opensource-src-4.1.3 containing the files from the archive. We only support the GNU version of the tar archiving utility. Note that on some systems it is called gtar. 3. Building To configure the Qt library for your machine type: cd /tmp/qt-x11-opensource-src-4.1.3 ./configure Type "./configure -help" to get a list of all available options. To create the library and compile all the demos, examples, tools, and tutorials, type: make To install the library, demos, examples, tools, and tutorials, type: su -c "make install" and enter the root password. Qt is by default installed into /usr/local/Trolltech/Qt-4.1.3 but this can be changed by using the -prefix parameter. Note that on some systems the make utility is named differently, e.g. gmake. The configure script tells you which make utility to use. If you need to reconfigure and rebuild Qt from the same location, ensure that all traces of the previous configuration are removed by entering the build directory and typing make confclean before running the configure script again. 4. Environment variables In order to use Qt, some environment variables needs to be extended. PATH - to locate qmake, moc and other Qt tools This is done like this: In .profile (if your shell is bash, ksh, zsh or sh), add the following lines: PATH=/usr/local/Trolltech/Qt-4.1.3/bin:$PATH export PATH In .login (in case your shell is csh or tcsh), add the following line: setenv PATH /usr/local/Trolltech/Qt-4.1.3/bin:$PATH If you use a different shell, please modify your environment variables accordingly. For compilers that do not support rpath you must also extended the LD_LIBRARY_PATH environment variable to include /usr/local/Trolltech/Qt-4.1.3/lib. On Linux with GCC this step is not needed. 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.
