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-4.2.2 directory, but this can be
changed by using the -prefix option. Alternatively, the
-prefix-install option can be used to specify a "local"
installation within the source directory.
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:
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.
Note that on some systems the make utility is named differently,
e.g. gmake. The configure script tells you which make utility to
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
before running the configure script again.
4. Environment variables
In order to use Qt, some environment variables needs to be
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
In .login (in case your shell is csh or tcsh), add the following line:
setenv PATH /usr/local/Trolltech/Qt-4.2.2/bin:$PATH
If you use a different shell, please modify your environment
For compilers that do not support rpath you must also extended the
LD_LIBRARY_PATH environment variable to include
/usr/local/Trolltech/Qt-4.2.2/lib. On Linux with GCC this step
is not needed.
5. That's all. Qt is now installed.
