Installing Qt for X11 Platforms

Qt for X11 has some requirements that are given in more detail in the Qt for X11 要求 文档。

Step 1: Installing the License File (commercial editions only)

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.

Step 2: Unpacking the Archive

Unpack the archive if you have not done so already. For example, if you have the qt-everywhere-opensource-src-%VERSION%.tar.gz package, type the following commands at a command line prompt:

cd /tmp
gunzip qt-everywhere-opensource-src-%VERSION%.tar.gz        # uncompress the archive
tar xvf qt-everywhere-opensource-src-%VERSION%.tar          # unpack it
					

This creates the directory /tmp/qt-everywhere-opensource-src-%VERSION% 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.

Step 3: Building the Library

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 选项。

cd /tmp/qt-everywhere-opensource-src-%VERSION%
./configure
					

类型 ./configure -help to get a list of all available options. The Configuration Options for Qt page gives a brief overview of these.

To create the library and compile all the demos, examples, tools, and tutorials, type:

make
					

-prefix is 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 install
					

Note that on some systems the make utility is named differently, e.g. gmake. The configure script tells you which make utility to use.

注意: 若以后需要在相同位置重新配置和重构 Qt,确保移除所有先前配置痕迹,通过进入构建目录并键入 make confclean 先于运行 configure 再次。

Step 4: Set the 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:

.profile (if your shell is bash, ksh, zsh or sh), add the following lines:

PATH=/usr/local/Trolltech/Qt-%VERSION%/bin:$PATH
export PATH
					

.login (in case your shell is csh or tcsh), add the following line:

setenv PATH /usr/local/Trolltech/Qt-%VERSION%/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-%VERSION%/lib . On Linux with GCC this step is not needed.

That's all. Qt is now installed.

Qt 演示和范例

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 Main menu.
