Introduction to Qt4

Qt is a comprehensive development framework that includes an extensive array of features, capabilities and tools that enable development of high-performance, cross-platform rich-client and server-side applications. Qt is the GUI framework on which KDE is built and Qt4 is the version of Qt that the upcoming KDE4 will use. You can of course use Qt for non-KDE applications as well, but if you wish to use KDE or any KDE-based applications, you must have Qt installed on your system.

Configuration Information

If you would like to compile with MySQL support add the following to the configure command: 

-plugin-sql-mysql -I/usr/include/mysql

If you would like to compile with PostgreSQL support add the following to the configure command: 

-plugin-sql-psql -I/usr/include/postgresql/server

If you would like to compile with SQLite support add the following to the configure command: 

-plugin-sql-sqlite2 -system-sqlite

If you would like to compile with SQLite3 support add the following to the configure command: 

-plugin-sql-sqlite -system-sqlite

If you would like to compile with unixODBC support add the following to the configure command: 

-plugin-sql-odbc

If you would like to compile with NAS support add the following to the configure command: 

-system-nas-sound

If you would like to disable Qt 3 support functionality add the following to the configure command: 

-no-qt3support

If your X Window System is NOT Xorg, then add to configure: 

-no-xfixes

If you want optimized qmake tool add the following to the configure command: 

-optimized-qmake

If you would like to disable GLib event loop add the following to the configure command: 

-no-glib

Non-Multilib

If you're X Window System prefix is something other then /usr/X11R6 then run the following command to change the hard coded paths in the sources: 

for file in $(grep -lr "X11R6" *)
do
    sed -i "s@/usr/X11R6@${XORG_PREFIX}@g" $file
    sed -i "s@{XORG_PREFIX}/lib64@${XORG_PREFIX}/lib@g" $file
done

Compile the package: 

mkdir -v /opt/qt-4.8.5 &&
ln -v -sfn qt-4.8.5 /opt/qt4 &&
