Installation of Qt4

Install Qt4 by running the following commands:

./configure -prefix           $QT4PREFIX \
            -sysconfdir       /etc/xdg   \
            -confirm-license             \
            -opensource                  \
            -release                     \
            -dbus-linked                 \
            -openssl-linked              \
            -system-sqlite               \
            -no-phonon                   \
            -no-phonon-backend           \
            -no-webkit                   \
            -no-openvg                   \
            -nomake demos                \
            -nomake examples             \
            -optimized-qmake             &&
make

This package does not come with a test suite.

Now as the root user:

make install &&
rm -rf $QT4PREFIX/tests

Remove references to the build directory from the installed .pc files by running the following command as the root user:

find $QT4PREFIX/lib/pkgconfig -name "*.pc" -exec perl -pi -e "s, -L$PWD/?\S+,,g" {} \;

Remove references to the build directory in the installed library dependency (prl) files by running the following command as the root user:

for file in $QT4PREFIX/lib/libQt*.prl; do
     sed -r -e '/^QMAKE_PRL_BUILD_DIR/d'    \
            -e 's/(QMAKE_PRL_LIBS =).*/\1/' \
            -i $file
done

Building Qtwebkit

The bundled version of qtwebkit in the main package requires an obsolete version of the gstreamer package. To overcome this, we use a more recent version available separately.

To start, the upstream package is unusual in that it does not come in a directory, so we have to create one before unpacking the tarball. After that, we need to make the package compatible with the latest version of gcc and use an included script to actually complete the build. To do this, run the following instructions:

mkdir qtwebkit-2.3.4 &&
pushd qtwebkit-2.3.4 &&

tar -xf ../../qtwebkit-2.3.4.tar.gz             &&
patch -Np1 -i ../../qtwebkit-2.3.4-gcc5-1.patch &&

QTDIR=$QT4PREFIX PATH=$PATH:$QT4PREFIX/bin \
Tools/Scripts/build-webkit --qt            \
                           --no-webkit2    \
                           --prefix=$QT4PREFIX

If desired, the build process can use parallel processors by adding the option --makeargs=-j<number> to the build-webkit instruction above.

To install the package, as the root user:

make -C WebKitBuild/Release install

Installing Auxillary Files

The following instructions assume that your working directory is the top of the Qt4 source tree:

popd

Install images and create the menu entries for installed applications. The QT4BINDIR variable is used here to point to the directory for the executable programs. If you have changed the bindir above, QT4BINDIR will need to be adjusted below. Be sure that the QT4BINDIR variable is defined in root's environment and as the root user:

QT4BINDIR=$QT4PREFIX/bin

Some packages such as VLC-2.2.1 look for certain executables with a -qt4 suffix. Run the following command as the root user to create the necessary symlinks:

  ln -sfrvn $QT4BINDIR/$file /usr/bin/$file-qt4
