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-mysql -I/usr/include/postgresql/server

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

-system-nas-sound

If your window system is NOT XORG, then add to configure:

Non-Multilib

Compile the package:

./configure -prefix /opt/qt-4.2.2 \
-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-4.2.2 /opt/qt &&
cp -v -r doc/man /opt/qt/doc &&
cp -v -r examples /opt/qt/doc

N32

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:

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

Compile the package

export QMAKESPEC=linux-g++-64 &&
./configure -prefix /opt/qt-4.2.2 \
-libdir /opt/qt-4.2.2/lib64 \
-plugindir /opt/qt-4.2.2/lib64/plugin \
-L/usr/lib64 \
-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-4.2.2/bin/qmake{,-64} &&
mv -v /opt/qt-4.2.2/bin/uic{,-64} &&
mv -v /opt/qt-4.2.2/bin/moc{,-64} &&
mv -v /opt/qt-4.2.2/bin/qtconfig{,-64} &&
ln -sfv /usr/bin/multiarch_wrapper /opt/qt-4.2.2/bin/qmake &&
ln -sfv /usr/bin/multiarch_wrapper /opt/qt-4.2.2/bin/uic &&
ln -sfv /usr/bin/multiarch_wrapper /opt/qt-4.2.2/bin/moc &&
ln -sfv /usr/bin/multiarch_wrapper /opt/qt-4.2.2/bin/qtconfig &&
cp -v -r doc/man /opt/qt-4.2.2/doc &&
cp -v -r examples /opt/qt-4.2.2/doc &&
ln -v -sfn qt-4.2.2 /opt/qt
