|
|
|
|
<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 file <filename>lib/pkgconfig/qt-mt.pc</filename> which must be
|
|
modified if relocating the package. This file is 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>This section will demonstrate two different methods.</para>

<note>
|
|
<para>The build time for <application>Qt</application> is quite long. If
|
|
you want to save some time and don't want the tutorials and examples,
|

change the first <command>make</command> command to:</para>

<title>Method 1 - Installing in the '/usr' Hierarchy</title>
|
|
|
|
<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>If <application>Qt</application> is being reinstalled, run the
|
|
following commands from a console or non-Qt based window manager.
|
|
It overwrites <application>Qt</application> libraries that should not
|
|
be in use during the install process.</para>
