Compiling Qt from source

Download

Download Qt sources

Build steps

Untar the archive:

 tar xvfz qt-x11-opensource-src-4.4.3.tar.gz

Configure Qt:

 cd qt-x11-opensource-src-4.4.3
 ./configure -prefix /usr/local/Trolltech/Qt-4.4.3

Accept the license offer GPLv2 or v3. Running the configuration script takes at least a few minutes. Compile Qt:

 make

Log in as 'root' to get permissions to write to /usr/local/Trolltech:

 su

Once logged in as 'root':

 make install
 exit

Alternatively, you can use sudo:

 sudo make install

Or, if you cannot log in as 'root', change the '-prefix' option to a path where you have write permissions.

Missing packages

You may encounter several errors if some required packages are not installed, especially development extension not present in default setups. Here follows lists of packages to install for Ubuntu and Fedora. Edit this document if you have experience with other distributions.
