{{Package-Introduction|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 [[KDE]]4 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.|http://www.trolltech.com/products/qt}}

== Dependencies ==

=== Required ===
* [[X Window System]]
* [[libjpeg]]
* [[libmng]]

=== Optional ===
* Xinerama provided by and [[X Window System]]
* Xfixes provided by and [[X Window System]]
* [[Glib2]]
* [[MySQL]]
* [[NAS]]
* [[CUPS]]
* [[PostgreSQL]]
* [[unixODBC]]
* [[SQLite]]
* [[Firebird]]

== 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 [[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 your [[X Window System]] is <font color="red">'''NOT'''</font> Xorg, then add to configure:

 -no-xfixes

== 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
 done

Compile the package:

 ./configure -prefix /opt/qt-{{Qt4-Version}} \
 -plugindir /usr/lib/plugins
 -sysconfdir /etc/qt4 \
 -qt-gif \
 -system-zlib \
 -system-libpng \
 -system-libjpeg \
 -system-libmng \
 -no-exceptions \
 -tablet &&
 make

Install the package

 make install &&
 ln -v -sfn qt-{{Qt4-Version}} /opt/qt4

== Multilib ==

=== 32Bit ===

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
 done

Compile the package

 export QMAKESPEC=linux-g++-32 &&
 PKG_CONFIG_PATH="${PKG_CONFIG_PATH32}" \
 ./configure -prefix /opt/qt-{{Qt4-Version}} \
 -libdir /opt/qt-{{Qt4-Version}}/lib \
 -plugindir /opt/qt-{{Qt4-Version}}/lib/plugins \
 -L/usr/lib \
 -sysconfdir /etc/qt4 \
 -qt-gif \
 -system-zlib \
 -system-libpng \
 -system-libjpeg \
 -system-libmng \
 -no-exceptions \
 -tablet &&
 make

Install the package

 make install &&
 mv -v /opt/qt-{{Qt4-Version}}/bin/qmake{,-32} &&
 mv -v /opt/qt-{{Qt4-Version}}/bin/uic{,-32} &&
 mv -v /opt/qt-{{Qt4-Version}}/bin/uic3{,-32} &&

TO BE DONE

=== 64Bit ===

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:

Create two qconfig.h header files which select the actual architecture-dependent qconfig-{32,64}.h header files:

{{Stub-Header|qtconfig|/opt/qt-{{Qt4-Version}}/include/Qt}}
{{Stub-Header|qtconfig|/opt/qt-{{Qt4-Version}}/include/QtCore}}
