<title>Installation of Qt4</title>
|
|
|
|
<para>There are several ways to install a complicated package such as
|
|
<application>Qt4</application>. The files are not completely position
|
|
independent. Installation procedures execute the program
|
|
<command>pkg-config</command> to determine the location of package
|
|
executables, libraries, headers, and other files. For
|
|
<application>Qt4</application>, <command>pkg-config</command> will look
|
|
for the appropriate <filename>lib/pkgconfig/Qt*.pc</filename> files which
|
|
must be modified if relocating the package. These files are set up correctly
|
|
by the build process.</para>
|
|
|
|
<para>The default installation places the files in
|
|
<filename class='directory'>/usr/local/qt/</filename>. Many commercial
|
|
distributions place the files in the system's
|
|
<filename class='directory'>/usr</filename> hierarchy. The package can
|
|
also be installed in an arbitrary directory.</para>
|
|
|
|
<para>The advantage of this method is that no updates to the
|
|
<filename>/etc/ld.so.conf</filename> or
|
|
<filename>/etc/man_db.conf</filename> files are required. The package
|
|
files are distributed within several subdirectories of the
|
|
<filename class='directory'>/usr</filename> hierarchy.
|
|
This is the method that most commercial distributions use.</para>
|
|
|
|
<note>
|
|
<para>There is no conflict between the <application>Qt3</application>
|
|
and <application>Qt4</application> applications and headers so both
|
|
can be installed at the same time. This may be necessary to build or
|
|
run Qt3 applications like <application>KDE3</application> and
|
|
<application>Qt4</application> applications like
|
|
<application>Doxygen</application>'s <application>doxywizard</application>
|
|
on the same system.
|
|
</para>
|
|
|
|
<para>To set up both <application>Qt3</application> and
|
|
<application>Qt4</application> on the same system, choose the primary
|
|
version for the <filename>/opt/qt</filename> symbolic link and add
|
|
the explicit library directory of the other version to
|
|
<filename>/etc/ld.so.conf</filename>.</para>
|
|
|
|
<para>On a system with both versions ot Qt, there is a name conflict with
|
|
Qt applications such as <filename>qmake</filename>,
|
|
<filename>assistant</filename>, and <filename>designer</filename>. In
|
|
such a case, make sure the PATH variable lists the proper
|
|
<filename>/opt/qt<version>/bin</filename> directory before the
|
|
other Qt bin directory. </para>
|
|
</note>
|
|
|
|
<caution>
|
|
<para>If <application>Qt4</application> is being reinstalled and the
|
|
<filename class='directory'>/usr</filename>
|
|
directory is used as the prefix, run the following commands from a
|
|
console or non-Qt4 based window manager. It overwrites
|
|
<application>Qt4</application> libraries that should not be in use during
|
|
the install process.</para>
|
|
</caution>
|
|
|
|
<note>
|
|
<para>The build time and space required for the full
|
|
<application>Qt4</application> is quite long. The instructions below do
|
|
not build the tutorials and examples. Removing the
|
|
<parameter>-nomake</parameter> lines will create a complete build.</para>
|
|
</note>
|
|
|
|
<para>The method recommended by the <application>Qt4</application>
|
|
developers does not use the /usr directory prefix. It has the advantage of
|
|
keeping all the package files consolidated in a dedicated directory
|
|
hierarchy. By using this method, an update can be made without overwriting
|
|
a previous installation and users can easily revert to a previous version
|
|
by changing one symbolic link.</para>
|
|
|
|
<para>The <application>Qt4</application> developers use a default location
|
|
of <filename class='directory'>/usr/local/qt/</filename>, however the
|
|
procedure below puts the files in <filename
|
|
class='directory'>/opt/qt-&qt4-version;/</filename>
|
|
and then creates a symbolic link to <filename>/opt/qt/</filename>.</para>
