<h2>16.3. CLR & Mono</h2>
<p>The Mono Project is an open development initiative sponsored by Ximian
that is working to develop an open source, Unix version of the Microsoft .NET
development and run time platform. Its objective is to enable Unix developers to build
and deploy cross-platform .NET Applications. Likewise, this expands the
capabilities of Windows programmers, this project opens .NET to non
Windows platforms. Mono will implement various Microsoft technologies that
have now been submitted to the ECMA for standardization.</p>
<p>The Goal is similar to that of Java, implementing a common virtual machine
on multiple operating systems, however you are not restricted to one
language.</p>
<p>Like .NET, Mono contains a Common Language Infrastructure (CLI) virtual,
machine that contains a class loader, Just-in-time compiler, and a garbage
collecting runtime; a class library that can work with any language which
works on the CLR; a compiler for the C# language.</p>
<p>Windows has compilers that target the virtual machine from a number
of languages: Managed C++, JavaScript, Eiffel, Component Pascal, APL, Cobol,
Perl, Python, Ruby, Scheme, Smalltalk, Standard ML, Haskell, Mercury and Oberon.
A single object system, threading system, class libraries, and garbage
collection system can be shared across all these languages, the CLR.</p>
<p>The CLR and the Common Type System (CTS) enables applications and
libraries to be written in a collection of different languages that target
the CLR byte code. This means that you could define a class to do algebraic
manipulation written in C#, that class can be reused from any other
language that supports the CLI. You could create a class in C#, subclass
it in C++ and instantiate it in an Eiffel program.</p>

<h3>16.3.1. Environment Setup</h3>
<p>Ximian announced the launch of the Mono project, an effort to create
an open source implementation of the .NET Development Framework.</p>
<p>Follow the steps below to configure the CLR runtime environment
with Virtuoso:</p>
<ol>
<li>
<div class="formalpara">
<strong>Install Mono</strong>
<p>The Mono package is available from the
<a href="http://www.go-mono.com/">Mono project home page</a> in the
form of an RPM for Linux. The source is also available.</p>
</div>
</li>
<li>
<div class="formalpara">
<strong>Make mscorlib.dll available to /usr/local/lib</strong>
<p>The mscorlib.dll is installed by Mono and needs to be symlinked from
its default location to <span class="computeroutput">/usr/local/lib</span>.</p>
</div>
</li>
</ol>
<br />

<h3>16.3.2. Testing the Virtuoso Mono Runtime Environment</h3>
<p>To test that you have successfully started the Virtuoso server with
Mono CLR runtime support make a simple library, import the contained class
into Virtuoso and call it.</p>
<p>Using an text editor create a C# source file in the server
root directory called sanity.cs, with the following contents:</p>
<div>
<pre class="programlisting">
using System;
public class sanity
{
public static string test(string name) {
return "Hello "+ name + ", from Virtuoso";
}
}
</pre>
</div>
<p>This sample needs to be compiled into bytecode assembly before it can
be used. Make sure you environment is configured to use Mono,
change directory to the Virtuoso server root containing the C# source file. Run:</p>
<div>
<pre class="programlisting">
bash$ mcs /target:library sanity.cs
Compilation succeeded
</pre>
</div>
<p>Now this library must be introduce to the Virtuoso Server. Using ISQL
use the following commands to test the CLR:</p>
<div>
<pre class="programlisting">
C:\Program Files\OpenLink\Virtuoso 3.0\bin>isql 1112
Connected to OpenLink Virtuoso
Driver: 03.00.2315 OpenLink Virtuoso ODBC Driver
OpenLink Interactive SQL (Virtuoso), version 0.9849b.
Type HELP; for help and EXIT; to exit.
SQL> DB..import_clr (vector ('sanity'), vector ('sanity'));
Done. -- 300 msec.
SQL> select sanity::test('Rob');
callret
VARCHAR
______________________________________________
Hello Rob, from Virtuoso
1 Rows. -- 60 msec.
</pre>
</div>
<p>Congratulations, you have proven that your Virtuoso server
can run .NET classes via Mono Runtime.</p>
<div class="tip">
<div class="tiptitle">See Also:</div>
<p>The Virtuoso Tutorials, which are installed with the Demo Virtuoso
Server (port 1112), contains numerous samples further demonstrating the use
of the CLR, .NET, Mono and Virtuoso.</p>
