<p> You may need to be root, depending on the permissions of the directories
where you choose to install TQt.
<p> <ol type=1>
<li> Unpack the archive if you have not done so already:
<p> <pre>
cd /usr/local
gunzip qt-x11-version.tar.gz # uncompress the archive
tar xf qt-x11-version.tar # unpack it
</pre>
<p> This creates the directory /usr/local/qt-<em>version</em> containing the
files from the main archive.
<p> Rename qt-<em>version</em> to qt (or make a symlink):
<p> <pre>
mv qt-version qt
</pre>
<p> The rest of this file assumes that TQt is installed in <tt>/usr/local/qt</tt>.
<p> <li> Set some environment variables in the file <tt>.profile</tt> (or <tt>.login</tt>,
depending on your shell) in your home directory. Create the
file if it is not there already.
<p> <ul>
<li> QTDIR -- the directory in which you're building TQt
<li> PATH -- to locate the <a href="moc.html#moc">moc</a> program and other TQt tools
<li> MANPATH -- to access the TQt man pages
<li> LD_LIBRARY_PATH -- for the shared TQt library
</ul>
<p> This is done like this:
<p> In <tt>.profile</tt> (if your shell is bash, ksh, zsh or sh), add the
following lines:
<p> <pre>
QTDIR=/usr/local/qt
PATH=$QTDIR/bin:$PATH
MANPATH=$QTDIR/man:$MANPATH
LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
export QTDIR PATH MANPATH LD_LIBRARY_PATH
</pre>
<p> In <tt>.login</tt> (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> After you have done this, you will need to login again, or
re-source the profile before continuing, so that at least <tt>$QTDIR</tt>
is set. The installation will give an error message and not
proceed otherwise.
<p> On AIX set LIBPATH and on HP-UX set SHLIB_PATH instead of LD_LIBRARY_PATH.
<p> Note that the SGI MIPSpro o32 and Sun WorkShop 5.0 targets are no
longer supported as of TQt 3.3.
<p> <li> Install your license file as <tt>$HOME/.qt-license</tt>.
For the free edition and evaluation version, you do not need a license
file.
<p> <li> Compile the TQt library, and build the example programs,
the tutorial and the tools (e.g. <a href="designer-manual.html">TQt
Designer</a>) as follows.
<p> Type:
<pre>
./configure
</pre>
<p> This will configure the TQt library for your machine. Note that
GIF support is turned off by default. Run <tt>./configure -help</tt>
to get a list of configuration options. Read <tt>PLATFORMS</tt> for a
list of supported platforms.
<p> To create the library and compile all examples and the tutorial:
<pre>
make
</pre>
If 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 <tt>/sbin/ldconfig</tt> 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 'libtqt.so.2'
</pre>
you probably need to put a reference to the qt library in a
configuration file and run <tt>/sbin/ldconfig</tt> as root on your system.
And don't forget to <tt>set</tt> LD_LIBRARY_PATH as explained in 2) above.
<p> <li> The online HTML documentation is installed in <tt>/usr/local/qt/doc/html/</tt>
The main page is <tt>/usr/local/qt/doc/html/index.html</tt>.
The man pages are installed in <tt>/usr/local/qt/doc/man/</tt>.
The documentation is also accessible using <a href="assistant.html">TQt
Assistant</a>.
</ol>
<p> You're done. TQt is now installed.
