			<content:encoded><![CDATA[<p>First of all I would like PHP5 ZIP Support under MacOS X Snow Leopard. So there is an easy PECL Extension that could be installed with, but it wouldn&#8217;t work:<br />
<code>
<pre>$ pecl install zip
[...]
php_pcre.h:29:18: error: pcre.h: No such file or directory
php_zip.c:602: error: 'pcre' undeclared (first use in this function)
[...]</pre>
<p></code></p>
<p>Now i started to compile PHP myself, &#8230; *waiting*waiting*error*killing myself*waiting* &#8230; Okey it takes to long time. Currently i&#8217;ve found an really easy way to fix this problem.</p>
<p>First: Install <a href="http://www.macports.org/">MacPorts</a>, it requires XCode.<br />
Second: Compile PCRE with MacPorts<br />
<code>
<pre>port install pcre</pre>
<p></code><br />
Third: Install the PECL ZIP extension via this special command :P<br />
<code>
<pre>$ CPPFLAGS="-I/opt/local/include" pecl install zip</pre>
<p></code><br />
Fifth: Add the extension to the php.ini file <i>/etc/php.ini</i><br />
<code>
<pre>extension=zip.so</pre>
<p></code></p>
<p>Restart your apache and thats it ;)</p>

			<content:encoded><![CDATA[<p>Da leider bei uns an der <a href="http://www.hs-weingarten.de">Hochschule Ravensburg-Weingarten</a> in einigen Analysis II Vorlesungen kein Skript angeboten wurde habe ich nun angefangen hierfür eines zu schreiben.</p>
<p><img src="http://www.cyber-tec.org/wp-content/uploads/2010/02/vegetable_meets_mathematics.jpg" alt="" title="vegetable_meets_mathematics" width="500" height="394" class="alignnone size-full wp-image-1072" /></p>
<p>Das Skript wird komplett in LaTex verfasst, da dort die ganzen Formeln relativ einfach umgesetzt werden können. Hier mal noch einige nützliche Informationen:</p>
<ul>
<li><a href="http://mo.mathematik.uni-stuttgart.de/kurse/kurs44/index_full.html">Mathematik-Online: LaTex</a></li>
<li><a href="http://de.wikipedia.org/wiki/Hilfe:TeX">Wikipedia: TeX</a></li>
<li><a href="http://de.wikibooks.org/wiki/LaTeX-Wörterbuch">Wikibooks: LaTex-Wörterbuch</a></lI>
</ul>
<p>Aktueller Zwischenstand sind ca. 28 Seiten und noch 50 Seiten zu schreiben. Ich hoffe das dies Studenten aus den nachfolgenden Semestern etwas weiterbringt und nicht alles während der Vorlesung mitschreiben müssen.</p>
<p>In den nächsten Tagen möchte ich einen Vorentwurf zum Download anbieten, vielleicht findet Ihr einige Fehler :-)</p>
