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.

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.


Installing Qt3 in /usr

If you want to install Qt3 in /usr, these are in the instructions to do so. If you want to install it in /opt, the instructions are below.

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

Fix the location of some qt directories: 

sed -i -e 's:$(QTDIR)/include:&/qt:' \
       -e 's:$(QTDIR)/lib:&/qt:' \
  mkspecs/linux*/qmake.conf

Compile the package: 

 bash
 export PATH=$PWD/bin:$PATH &&
 export LD_LIBRARY_PATH=$PWD/lib:$LD_LIBRARY_PATH &&

 ./configure -prefix /usr \
 -docdir /usr/share/doc/qt \
 -headerdir /usr/include/qt \
 -datadir /usr/share/qt \
 -plugindir /usr/lib/qt/plugin \
 -translationdir /usr/share/qt/translations \
 -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 &&

 find -type f -name Makefile | xargs sed -i "s@-Wl,-rpath,/usr/lib@@g" &&
 make &&
 exit

Install the package: 

 make install &&

 cp -Rv doc/man /usr/share &&
 cp -Rv examples /usr/share/doc/qt &&

 ln -svf libqt-mt.so /usr/lib/libqt.so

Command Explanations

find -type f -name Makefile | xargs sed -i "s@-Wl,-rpath,/usr/lib@@g": This command removes the harcoding of /usr/lib in a number of files.

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

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.

Non-Multilib and Multilib

Note that this file isn't really necessary in most cases since /usr is already in the search path, but there are a few packages that care about QTDIR and some of the packages in CBLFS have instructions that include QTDIR, so creating this file means that those instructions should work correctly without any modification. 

cat > /etc/profile.d/20-qt.sh << "EOF"
# Begin /etc/profile.d/20-qt.sh

export QTDIR=/usr

# End /etc/profile.d/20-qt.sh
EOF

There is no need to update ld.so.conf when installing Qt3 in /usr.
