Compiling Qt from source
Download Qt sources
Untar the archive:
tar xvfz qt-x11-opensource-src-4.4.3.tar.gz
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:
Log in as 'root' to get permissions to write to /usr/local/Trolltech:
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.
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.
Under Fedora Core 7, the following packages were installed before Qt:
glibc-headers kernel-headers glibc-headers glibc-devel gcc libstdc++-devel gcc-c++ glib2 glib libXau-devel libXdmcp-devel xorg-x11-proto-devel mesa-libGL-devel libX11-devel libXext-devel libXext freetype-devel fontconfig-devel libXcursor-devel libXrender libXrender-devel zlib-devel
To summarize: g++ and headers for X11 libraries. libXext and libXrender did not exist in this default installation of Fedora Core 7.
