<h1 align=center> Installing Qt/X11</h1><br clear="all">
<p>
You may need to be root, depending on the permissions of the directories
where you choose to install Qt.
<p>
<ul>
<li>Unpack the archive if you have not done so already:
<p>
<pre>
cd /usr/local
gunzip qt-x11-<i>version</i>.tar.gz # uncompress the archive
tar xf qt-x11-<i>version</i>.tar # unpack it
</pre>
<p>
This creates the directory /usr/local/qt-<i>version</i> containing the
files from the main archive.
<p>
Rename qt-<i>version</i> to qt (or make a symlink):
<pre>
mv qt-<i>version</i> qt
</pre>
The rest of this file assumes that Qt is installed in /usr/local/qt.
</p>
<li>Set some environment variables in the file .profile (or .login,
depending on your shell) in your home directory. (Create the
file if it is not there already.)
<p>
<table>
<tr><td>QTDIR <td> wherever you installed Qt
<tr><td>PATH <td> to locate the moc program and other Qt tools
<tr><td>MANPATH <td> to access the Qt man pages
<tr><td>LD_LIBRARY_PATH <td> for the shared Qt library
<tr><td>QT_FONTPATH <td> optional. A list of directories where Qt can find type1 or true type fonts for
print embedding.
</table>
<p>
This is done like this:
<p>
In .profile (if your shell is bash, ksh, zsh or sh), add the
following lines:
<pre>
QTDIR=/usr/local/qt
PATH=$QTDIR/bin:$PATH
MANPATH=$QTDIR/man:$MANPATH
LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
<p>
export QTDIR PATH MANPATH LD_LIBRARY_PATH
</pre>
<p>
In .login (in case your shell is csh or tcsh), add the following lines:
<p>
<pre>
setenv QTDIR /usr/local/qt
setenv PATH $QTDIR/bin:$PATH
setenv MANPATH $QTDIR/man:$MANPATH
setenv LD_LIBRARY_PATH $QTDIR/lib:$LD_LIBRARY_PATH
</pre>
<p>
If you have some true type or type1 fonts installed in non
standard places, you might want to set the QT_FONTPATH environment
variable to point to these directories. This is not needed, when
all fonts are accessed through local font directories or a local
font server, as Qt will automatically scan the fontpath and the
font servers configuration file. All directories in the fontpath
will need to have a valid fonts.dir file, so Qt can map from X11
font names to the corresponding embeddable font.
</p>
<p>
After you have done this, you will need to login again, or
re-source the profile before continuing, so that at least $QTDIR
is set. The installation will give an error message and not
proceed otherwise.
</p>
<li> Install your license file. For the free edition, you do not need
a license file. For Professional and Enterprise editions, install
your license file as described in your distribution.
</p>
<li> Building.
<p>
This step compiles the Qt library, and builds the example programs,
the tutorial, and the tools (eg. the Designer).
<p>
Type:
<pre>
./configure
</pre>
<p>
This will configure the Qt library for your machine. Note that
GIF support is turned off by default. Run ./configure -help
to get a list of configuration options. Read PLATFORMS for a
list of supported platforms.
<p>
To create the library and compile all examples and the tutorial:
<pre>
make
</pre>
If your platform or compiler is not supported, read PORTING. If it is
supported but you have problems, see <a href=http://www.trolltech.com/platforms/>http://www.trolltech.com/platforms/</a>
</p>
<li> In very few cases you may need to run /sbin/ldconfig or something
similar at this point if you are using shared libraries.
<p>
If you have problems running the example programs, e.g. messages like
<pre>
can't load library 'libqt.so.2'
</pre>
you probably need to put a reference to the qt library in a
configuration file and run /sbin/ldconfig as root on your system.
And don't forget to set LD_LIBRARY_PATH as explained in 2) above.
</p>
<li> The online HTML documentation is installed in /usr/local/qt/doc/html/
The main page is /usr/local/qt/doc/html/index.html
The man pages are installed in /usr/local/qt/doc/man/
</p>
</ul>
<p>
You're done. Qt is now installed.
