<h1>QGLViewer - RPM installation</h1>
<h2>Pre-compiled RPMs</h2>
The easiest way to install the library is to use the RPM pre-compiled version (compiled with gcc 3.2.2):
<pre>
> rpm -Uvh <a href="http://artis.imag.fr/Members/Gilles.Debunne/QGLViewer/src/libQGLViewer-1.3.6-1.i586.rpm">libQGLViewer-1.3.6-1.i586.rpm</a> <a href="http://artis.imag.fr/Members/Gilles.Debunne/QGLViewer/src/libQGLViewer-devel-1.3.6-1.i586.rpm">libQGLViewer-devel-1.3.6-1.i586.rpm</a>
</pre>
<h2>Compiling from the sources</h2>
You can also rebuild all the sources using the RPM source package:
<pre>
> rpm --rebuild <a href="http://artis.imag.fr/Members/Gilles.Debunne/QGLViewer/src/libQGLViewer-1.3.6-1.src.rpm">libQGLViewer-1.3.6-1.src.rpm</a>
> rpm -Uvh /usr/src/RPM/RPMS/i?86/libQGLViewer-*1.3.6-1.i?86.rpm
</pre>
You may want to tune the sources to fit your local installation:
<pre>
> rpm -Uvh <a href="http://artis.imag.fr/Members/Gilles.Debunne/QGLViewer/src/libQGLViewer-1.3.6-1.src.rpm">libQGLViewer-1.3.6-1.src.rpm</a>
Edit /usr/src/RPM/SPECS/libQGLViewer-1.3.6.spec (tune QTDIR, install dir,...)
Uncompress the sources in /usr/src/RPM/SOURCES/libQGLViewer-1.3.6.tar.gz, edit, and recompress.
> rpm -ba /usr/src/RPM/SPECS/libQGLViewer-1.3.6.spec
> rpm -Uvh /usr/src/RPM/RPMS/i?86/libQGLViewer-*1.3.6-1.i?86.rpm
</pre>
<h2>RPM contents</h2>
The rpm installs the following files on your machine:
<ul>
<li>The library (<code>libQGLViewer-1.3.6.so</code>) in <b><code>/usr/local/lib</code></b></li>
<li>The header files in <b><code>/usr/local/include/QGLViewer</code></b></li>
<li>The documentation and the examples in <b><code>/usr/share/doc/QGLViewer</code></b></li>
</ul>
The rpm can also be downloaded from
<a href="http://rpmfind.net/linux/rpm2html/search.php?query=libQGLViewer">rpmFind.net</a> or
<a href="http://rpm.pbone.net">pbone.net</a>.
<h2>Troubleshooting</h2>
When installing the QGLViewer library, you may be prompted some dependency error messages. Missing
RPMs can be downloaded from these official sites : <a href="http://rpmfind.net">rpmfind.net</a>,
<a href="http://rpm.pbone.net">pbone.net</a> and
<a href="http://www.google.com/search?q=rpm+repository">Google</a>.
<ul>
<li><b>libGL dependency</b> : If you didn't use an RPM to install <code>libGL</code> (e.g. you used
the NVidia script), you may have to add <code>--force</code> to the installation options.</li>
<li><b>Qt-devel</b> : QT is usually shipped in the distribution CDs. You may however have to
install the <i>qt3-devel</i> package (<code>ls $QTDIR/lib</code> to find your Qt version).</li>
<li><b>Random display</b> : You are probably running a gcc 3.2 optimized version of the library. This
is gcc 3.2 bug, fixed in gcc 3.2.2. The patch should automatically be applied. In case of trouble,
edit <code>QGLViewer/QGLViewer.pro</code>, replace <code>release</code> by <code>debug</code> and re-compile.</li>
<li><b>libqt-mt</b> : QGLViewer is compiled with the <i>multi-thread</i> (qt-mt) version of qt. If you
only have <code>libqt.so</code> installed, edit <code>QGLViewer/QGLViewer.pro</code>, remove
<code>thread</code> and re-compile.</li>
<li><b>libGLcore.so.1</b> : This package used to be listed in the dependency list, but it should no longer be the case.</li>
<li><b>lib3ds</b> : Download the patched
<a href="http://artis.imag.fr/Members/Gilles.Debunne/QGLViewer/src/lib3ds-1.2.0-1.i686.rpm">lib3ds-1.2.0-1.i686.rpm</a>
(<a href="http://artis.imag.fr/Members/Gilles.Debunne/QGLViewer/src/lib3ds-1.2.0-1.i686.rpm">lib3ds-1.2.0-1.i586.gcc2.rpm</a> for gcc 2.96)
or the sources: <a href="http://artis.imag.fr/Members/Gilles.Debunne/QGLViewer/src/lib3ds-1.2.0-1.src.rpm">lib3ds-1.2.0-1.src.rpm</a> or <a href="http://artis.imag.fr/Members/Gilles.Debunne/QGLViewer/src/lib3ds-1.2.0.tar.gz">lib3ds-1.2.0.tar.gz</a>.</li>
<li><b>libX3DTK</b> : Download the library from the <a="http://www-artis.imag.fr/Members/Yannick.Legoc">X3DTK web site</a>.
