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.
