The following software is necessary to start i3Geo correctly (if the MS4W package is used, it's not necessary to install any other software, only R and its libraries):</p>
<ul style="margin-left: 40px;">
<li>
Apache;</li>
<li>
PHP 5;</li>
<li>
Mapserver;</li>
<li>
PHP MapScript.</li>
<li>
<a href="http://cran-r.c3sl.ufpr.br/" target="_blank">R</a> + <a href="http://www.r-project.org/" target="_blank">spatstat</a> library + <a href="http://cran.r-project.org/web/packages/deldir" target="_blank">deldir</a> library. In <strong>Linux</strong>, <a href="http://en.wikipedia.org/wiki/Ghostscript" target="_blank">Ghostscript</a> must be installed too. If R is not installed, some functionalities for graphics management and analysis of distribution points won't be able to be executed.</li>
</ul>
<p>
In case of compiling MapServer, made in Linux systems generally, the options GEOS, WMS/WFS client and WMS/WFS server must be used. Example of the "<em>mapserv.exe -v"</em> command for a standard installation:</p>
<p style="margin-left: 40px;">
MapServer version 5.2.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP OUTPUT=PDF OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=ICONV SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI SUPPORTS=THREADS SUPPORTS=GEOS SUPPORTS=RGBA_PNG INPUT=JPEG INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE</p>
<p>
The following extensions must be enabled in PHP too:</p>
<ul style="margin-left: 40px;">
<li>
php_mbstring</li>
<li>
php_gd</li>
<li>
php_xmlrpc</li>
<li>
php_xsl</li>
<li>
curl</li>
<li>
php_pdo</li>
<li>
pdo for sqlite or another database that is used by the administration system</li>
</ul>
<p>
Like the i3Geo version, the list of dependencies can have specific characteristics. See these link for more information:</p>
