Introduction to Qt3

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 Qt3 is the version of Qt that KDE3 uses. 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.

Note: These instructions assume that you want to install
Qt3 with /opt as the prefix instead of the normal /usr.
If you wish to install Qt3 in /usr, then you will need
to adjust the commands accordingly.

Dependencies

Required

Optional

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

Note to DESTDIR Fans

Unfortunately Qt3 ignores DESTDIR. However, it uses INSTALL_ROOT for the same purpose, so use INSTALL_ROOT as you would normally use DESTDIR.

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-3.3.8 \
-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-3.3.8 /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-3.3.8 \

-system-libmng \
-plugin-imgfmt-png \
-plugin-imgfmt-jpeg \
-plugin-imgfmt-mng \

make &&
exit

Install the package

make install &&
mv -v /opt/qt-3.3.8/bin/qmake{,-32} &&
mv -v /opt/qt-3.3.8/bin/uic{,-32} &&
mv -v /opt/qt-3.3.8/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

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.
