|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
<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> TQTDIR -- 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>
|
|
|
|
|
TQTDIR=/usr/local/qt
|
|
|
|
|
PATH=$TQTDIR/bin:$PATH
|
|
|
|
|
MANPATH=$TQTDIR/man:$MANPATH
|
|
|
|
|
LD_LIBRARY_PATH=$TQTDIR/lib:$LD_LIBRARY_PATH
|
|
|
|
|
|
|
|
|
|
export TQTDIR 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 TQTDIR /usr/local/qt
|
|
|
|
|
setenv PATH $TQTDIR/bin:$PATH
|
|
|
|
|
setenv MANPATH $TQTDIR/man:$MANPATH
|
|
|
|
|
setenv LD_LIBRARY_PATH $TQTDIR/lib:$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>$TQTDIR</tt>
|
|
|
|
|
is set. The installation will give an error message and not
|
|
|
|
|
proceed otherwise.
|
|
|
|
|
<p> On AIX set LIBPATH and on HP-UX set SHLIB_PATH instead of LD_LIBRARY_PATH.
|
|
|
|
|
<p> Note that the SGI MIPSpro o32 and Sun WorkShop 5.0 targets are no
|
|
|
|
|
longer supported as of TQt 3.3.
|
|
|
|
|
<p> <li> Install your license file as <tt>$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.
