<title>Installation of Qt</title>
- <warning>
+ <para>
+ There are several ways to install a complicated package such as
+ <application>Qt</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>Qt</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 installing in <filename
+ class="directory">/usr</filename> 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. It is also supported by the
+ <application>qtchooser</application> application.
+ </para>
+
+ <para>
+ The advantage of installing <application>Qt</application> in a custom
+ directory such as <filename
+ class="directory">/opt/qt-&qt4-version;</filename> is that it keeps 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 or merely changing the PATH variable. It
+ also allows a developer to maintain multiple versions of
+ <application>Qt</application> for testing.
