Introduction to Qt

The Qt package contains a C++ GUI library. This is useful for creating graphical applications or executing graphical applications that are dynamically linked to the Qt library. One of the major users of Qt is KDE.

Dependencies

Required

• X Window System
• libjpeg
• libmng

Optional

• MySQL
• NAS
• CUPS
• PostgreSQL
• unixODBC
• SQLite
• Firebird

Extra

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

-qt-sql-mysql

And run this sed before compiling:

sed -i "s@mysql.h@mysql/mysql.h@g" src/sql/drivers/mysql/qsql_mysql.h

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

-system-nas-sound

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:

bash
export QTDIR=$PWD &&
export LD_LIBRARY_PATH=$PWD/lib:$LD_LIBRARY_PATH &&
export PATH=$PWD/bin:$PATH &&
./configure -prefix /opt/qt-3.3.6 \
-sysconfdir /etc/qt \
-qt-gif \
-system-zlib \
-system-libpng \
-system-libjpeg \
-system-libmng \
-plugin-imgfmt-png \
-plugin-imgfmt-jpeg \
-plugin-imgfmt-mng \
-no-exceptions \
-thread \
-tablet &&
make &&
exit

Install the package

make install &&
ln -v -sfn qt-3.3.6 /opt/qt &&
ln -v -s libqt-mt.so /opt/qt/lib/libqt.so &&
cp -v -r doc/man /opt/qt/doc &&
cp -v -r examples /opt/qt/doc

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:

bash
export QTDIR=$PWD &&
export LD_LIBRARY_PATH=$PWD/lib:$LD_LIBRARY_PATH &&
export PATH=$PWD/bin:$PATH &&
export QMAKESPEC=linux-g++-32 &&
./configure -prefix /opt/qt-3.3.6 \
-plugindir /opt/qt-3.3.6/lib/plugin \
-sysconfdir /etc/qt \

-system-libpng \
-system-libjpeg \
-system-libmng \
-plugin-imgfmt-png \
-plugin-imgfmt-jpeg \
-plugin-imgfmt-mng \
-no-exceptions \
-thread \
-tablet &&
make &&
exit

Install the package

make install &&
mv -v /opt/qt-3.3.6/bin/qmake{,-32} &&
mv -v /opt/qt-3.3.6/bin/uic{,-32} &&
mv -v /opt/qt-3.3.6/bin/moc{,-32} &&

Fix a known issue with QTSPEC linux-g++-64

sed -i "/^QMAKE_LIBDIR_QT/s:/lib:&64:" ${QTDIR}/mkspecs/linux-g++-64/qmake.conf

Configuring

profile.d/20-qt.sh

If you're using the setup defined in Bash Startup Files then run the following commands. If you're not using the setup defined in Bash Startup Files make sure that your enviornment is setup correctly.
