1、Installing Qt for Linux/X11 PlatformsQt for X11 has some requirements that are given in more detail in theQt for X11 Requirementsdocument.Before you start any actions, do this:sudo apt-get install libX11-dev libXext-dev libXtst-devStep 1: Installing the License File (commercial editions only)If you
2、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.Step 2: Unpacking the ArchiveUnpack the archive if you have not done so already. For example, if you have theqt-everywhere-opensource-src-4.8.5.tar.gzpackage, t
3、ype the following commands at a command line prompt: cd /tmp gunzip qt-everywhere-opensource-src-4.8.5.tar.gz # uncompress the archive tar xvf qt-everywhere-opensource-src-4.8.5.tar # unpack itThis creates the directory/tmp/qt-everywhere-opensource-src-4.8.5containing the files from the archive. We
4、only support the GNU version of the tar archiving utility. Note that on some systems it is called gtar.Step 3: Building the LibraryTo configure the Qt library for your machine type, run the./configurescript in the package directory.By default, Qt is configured for installation in the/usr/local/Troll
5、tech/Qt-4.8.5directory, but this can be changed by using the-prefixoption. cd /tmp/qt-everywhere-opensource-src-4.8.5 ./configureType./configure -helpto get a list of all available options. TheConfiguration Options for Qtpage gives a brief overview of these.To create the library and compile all the
6、demos, examples, tools, and tutorials, type: makeIf-prefixis outside the build directory, you need to install the library, demos, examples, tools, and tutorials in the appropriate place. To do this (as root if necessary), type: make installNote that on some systems the make utility is named differen
7、tly, e.g. gmake. The configure script tells you which make utility to use.Note:If you later 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 typingmake confcleanbefore runningconfigureagain
8、.Step 4: Set the Environment VariablesIn order to use Qt, some environment variables needs to be extended. PATH - to locate qmake, moc and other Qt toolsThis is done like this:In.profile(if your shell is bash, ksh, zsh or sh), add the following lines: PATH=/usr/local/Trolltech/Qt-4.8.5/bin:$PATH exp
9、ort PATHIn.login(in case your shell is csh or tcsh), add the following line: setenv PATH /usr/local/Trolltech/Qt-4.8.5/bin:$PATHIf you use a different shell, please modify your environment variables accordingly.For compilers that do not support rpath you must also extended theLD_LIBRARY_PATHenvironment variable to include/usr/local/Trolltech/Qt-4.8.5/lib. On Linux with GCC this step is not needed.Thats all. Qt is now installed.
