&lt;hr /&gt;
&lt;div&gt;=Installing from source=&lt;br /&gt;
&lt;br /&gt;
==MS Windows==&lt;br /&gt;
&lt;br /&gt;
OpenSim requires either the .Net framework version 2.0, or the latest Mono. It also is compiled with the C# and not the C++ IDE for those who are using the no-cost Express Editions from MS.&lt;br /&gt;
&lt;br /&gt;
=== Subversion Repository ===&lt;br /&gt;
&lt;br /&gt;
1. Get the source code from the svn repository:&lt;br /&gt;
&lt;br /&gt;
 http://opensimulator.org/svn/opensim/trunk&lt;br /&gt;
&lt;br /&gt;
=== Building ===&lt;br /&gt;
&lt;br /&gt;
2. In the top-level directory, run the '&amp;lt;tt&amp;gt;runprebuild.bat&amp;lt;/tt&amp;gt;' file. This will create both a VS2005 solution file, and a nant build file.&lt;br /&gt;
&lt;br /&gt;
3. Open the resulting sln file with visual studio, and build it there, or if you prefer to use nant, run nant in the same top-level directory. This will build the executables.&lt;br /&gt;
&lt;br /&gt;
If you don't care about physics (walking on prims, etc), ignore the rest of this section.&lt;br /&gt;
&lt;br /&gt;
==== Physics ====&lt;br /&gt;
&lt;br /&gt;
===== Open Dynamics Engine (ODE) =====&lt;br /&gt;
&lt;br /&gt;
If you want to implement collision-based physics, OpenDynamicsEngine (ODE) is the furthest along at the moment (9/07).  It is not fully supported, but is starting to work somewhat reliably using a small number of regions per sim.&lt;br /&gt;
&lt;br /&gt;
As installed from svn, ODE does not work on all platforms.  If you get an ODE-related crash, and/or an &amp;lt;i&amp;gt;ode.dll not found&amp;lt;/i&amp;gt; type of error (which can occur even though the dll is present!), try using the debug version of the dll, available here:&lt;br /&gt;
&lt;br /&gt;
http://www.squiggle.com/opensim/ode-debug.dll &amp;lt;br&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Rename it &amp;lt;tt&amp;gt;ode.dll&amp;lt;/tt&amp;gt; and put it in &amp;lt;tt&amp;gt;.\bin&amp;lt;/tt&amp;gt;, replacing the stock &amp;lt;tt&amp;gt;ode.dll&amp;lt;/tt&amp;gt;.  You can also try building &amp;lt;tt&amp;gt;ode.dll&amp;lt;/tt&amp;gt; from the latest version of the source (http://www.ode.org/; make sure to enable trimesh)&lt;br /&gt;
&lt;br /&gt;
=== Running ===&lt;br /&gt;
&lt;br /&gt;
Double-click on the &amp;lt;tt&amp;gt;OpenSim.exe&amp;lt;/tt&amp;gt; executable file in the &amp;lt;tt&amp;gt;bin&amp;lt;/tt&amp;gt; directory. This will start up OpenSim in standalone mode.&lt;br /&gt;
&lt;br /&gt;
The debugger in VS2005 C# may be used to step through the code. For those that use a Cygwin shell, you may find that one or more dll's have permissions that cause problems running. Most find that a &amp;quot;&amp;lt;tt&amp;gt;chmod 777 *&amp;lt;/tt&amp;gt;&amp;quot; from the &amp;lt;tt&amp;gt;bin&amp;lt;/tt&amp;gt; directory solves this.&lt;br /&gt;
&lt;br /&gt;
Physics can be invoked by adding the appropriate line to the [Startup] section of &amp;lt;tt&amp;gt;OpenSim.ini&amp;lt;/tt&amp;gt;.  For ODE, that would be:&lt;br /&gt;
&lt;br /&gt;
 physics = OpenDynamicsEngine&lt;br /&gt;
&lt;br /&gt;
You can also add a command line option to a shortcut, or run from a command prompt with:&lt;br /&gt;
&lt;br /&gt;
 -physics=OpenDynamicsEngine&lt;br /&gt;
&lt;br /&gt;
==Linux/Mac OS X==&lt;br /&gt;
&lt;br /&gt;
=== Subversion Repository ===&lt;br /&gt;
&lt;br /&gt;
To check out the latest revision:&lt;br /&gt;
&lt;br /&gt;
 svn co http://opensimulator.org/svn/opensim/trunk opensim&lt;br /&gt;
&lt;br /&gt;
Note: The &amp;lt;tt&amp;gt;libopenjpeg-libsl-...so&amp;lt;/tt&amp;gt; is not really working. For this reason you should download the newest libsecondlife from http://www.libsecondlife.org/, and build your own libopenjpeg library. If you use this instead of the SVN version, your sim will work fine.&lt;br /&gt;
&lt;br /&gt;
Notes to Mac OS X users: &lt;br /&gt;
&lt;br /&gt;
* OS X does not come packaged with subversion, so you will need to either install it or access the repository from a computer that does have subversion.&lt;br /&gt;
* You'll also need to install Mono.&lt;br /&gt;
* The version of Mono in MacPorts (formerly DarwinPorts) seems to be out of date and produced compilation errors on my system. You may have better luck installing the newest package from http://www.mono-project.com/Downloads&lt;br /&gt;
* Even with the newer version, there's a config problem with NAnt. There's a blog post here: http://bleepsoft.com/tyler/index.php?itemid=82 which explains how to fix the script (the blog post shows the path for 1.1.18 -- you'll need to replace this with 1.2.5 if you install the latest version from mono-project.com).&lt;br /&gt;
&lt;br /&gt;
=== Building (Mono) ===&lt;br /&gt;
&lt;br /&gt;
 cd opensim&lt;br /&gt;
 ./runprebuild.sh&lt;br /&gt;
 nant&lt;br /&gt;
&lt;br /&gt;
==== Physics ====&lt;br /&gt;
&lt;br /&gt;
If you want to implement collision-based physics, OpenDynamicsEngine (ODE) is the furthest along at the moment (9/07).  It is not fully supported, but is starting to work somewhat reliably using a small number of regions per sim.&lt;br /&gt;
&lt;br /&gt;
===== Open Dynamics Engine (ODE) =====&lt;br /&gt;
&lt;br /&gt;
As installed from svn, ODE does not work on all platforms.  If you get an ODE-related crash, and/or a &amp;lt;i&amp;gt;libode.so not found&amp;lt;/i&amp;gt; type of error, you will need to build libode from source.&lt;br /&gt;
&lt;br /&gt;
Remove &amp;lt;tt&amp;gt;libode.so&amp;lt;/tt&amp;gt; from the &amp;lt;tt&amp;gt;./bin&amp;lt;/tt&amp;gt; folder.  (Note that subsequent svn updates may replace it again; best fix is to copy your built &amp;lt;tt&amp;gt;libode.so&amp;lt;/tt&amp;gt; to &amp;lt;tt&amp;gt;bin&amp;lt;/tt&amp;gt;).  Do NOT remove &amp;lt;tt&amp;gt;ode.net.dll&amp;lt;/tt&amp;gt;!  Download the latest source packages from http://www.ode.org/.  When compiling, make sure to use the following configure options:&lt;br /&gt;
&lt;br /&gt;
 --with-trimesh=gimpact &lt;br /&gt;
 --enable-shared&lt;br /&gt;
&lt;br /&gt;
Make sure the configure script confirms these choices, and always compile with single precision (I believe that's the default).  Try &amp;lt;code&amp;gt; make -k &amp;lt;/code&amp;gt; if you get errors relating to drawstuff, test*, or openGL.  &amp;lt;code&amp;gt; make install &amp;lt;/code&amp;gt; should put &amp;lt;tt&amp;gt;libode.so&amp;lt;/tt&amp;gt; in the proper place (usually &amp;lt;tt&amp;gt;/usr/local/lib&amp;lt;/tt&amp;gt;), and it should be seen by opensim (&amp;lt;tt&amp;gt;ode.net.dll&amp;lt;/tt&amp;gt;)&lt;br /&gt;
&lt;br /&gt;
=== Running (Mono) ===&lt;br /&gt;
&lt;br /&gt;
 cd bin&lt;br /&gt;
 mono OpenSim.exe&lt;br /&gt;
&lt;br /&gt;
to invoke ODE, add the option:&lt;br /&gt;
 -physics=OpenDynamicsEngine&lt;br /&gt;
&lt;br /&gt;
or add &amp;lt;code&amp;gt;  physics = OpenDynamicsEngine &amp;lt;/code&amp;gt; to the [Startup] section of &amp;lt;tt&amp;gt;OpenSim.ini&amp;lt;/tt&amp;gt;.  Same deal for other physics engines, when available.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
As installed from svn, ODE does not work on all platforms.  If you get an ODE-related crash, and/or a &amp;lt;i&amp;gt;libode.so not found&amp;lt;/i&amp;gt; type of error, you will need to build libode from source.&lt;br /&gt;
&lt;br /&gt;
Remove &amp;lt;tt&amp;gt;libode.so&amp;lt;/tt&amp;gt; from the &amp;lt;tt&amp;gt;./bin&amp;lt;/tt&amp;gt; folder.  (Note that subsequent svn updates may replace it again; best fix is to copy your built &amp;lt;tt&amp;gt;libode.so&amp;lt;/tt&amp;gt; to &amp;lt;tt&amp;gt;bin&amp;lt;/tt&amp;gt;).  Do NOT remove &amp;lt;tt&amp;gt;ode.net.dll&amp;lt;/tt&amp;gt;!  Download the latest source packages from http://www.ode.org/.  When compiling, make sure to use the following configure options:&lt;br /&gt;
&lt;br /&gt;
 --with-trimesh=gimpact &lt;br /&gt;
 --enable-shared&lt;br /&gt;
&lt;br /&gt;
Make sure the configure script confirms these choices, and always compile with single precision (I believe that's the default).  Try &amp;lt;code&amp;gt; make -k &amp;lt;/code&amp;gt; if you get errors relating to drawstuff, test*, or openGL.  &amp;lt;code&amp;gt; make install &amp;lt;/code&amp;gt; should put &amp;lt;tt&amp;gt;libode.so&amp;lt;/tt&amp;gt; in the proper place (usually &amp;lt;tt&amp;gt;/usr/local/lib&amp;lt;/tt&amp;gt;), and it should be seen by opensim (&amp;lt;tt&amp;gt;ode.net.dll&amp;lt;/tt&amp;gt;)&lt;br /&gt;
&lt;br /&gt;
=== Running (Mono) ===&lt;br /&gt;
&lt;br /&gt;
 cd bin&lt;br /&gt;
 mono OpenSim.exe&lt;br /&gt;
&lt;br /&gt;
to invoke ODE, add the option:&lt;br /&gt;
 -physics=OpenDynamicsEngine&lt;br /&gt;
&lt;br /&gt;
or add &amp;lt;code&amp;gt;  physics = OpenDynamicsEngine &amp;lt;/code&amp;gt; to the [Startup] section of &amp;lt;tt&amp;gt;OpenSim.ini&amp;lt;/tt&amp;gt;.  Same deal for other physics engines, when available.&lt;br /&gt;
