Build Instructions

2007-09-08T04:38:02Z

MW1:

=Installing from source=

==MS Windows==

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.

=== Subversion Repository ===

1. Get the source code from the svn repository:

http://opensimulator.org/svn/opensim/

=== Building ===

2. In the top-level directory, run the '<tt>runprebuild.bat</tt>' file. This will create both a VS2005 solution file, and a nant build file.

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.

If you don't care about physics (walking on prims, etc), ignore the rest of this section.

==== Physics ====

===== Open Dynamics Engine (ODE) =====

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.

As installed from svn, ODE does not work on all platforms. If you get an ODE-related crash, and/or an ode.dll not found type of error (which can occur even though the dll is present!), try using the debug version of the dll, available here:

http://www.squiggle.com/opensim/ode-debug.dll 

Rename it <tt>ode.dll</tt> and put it in <tt>.\bin</tt>, replacing the stock <tt>ode.dll</tt>. You can also try building <tt>ode.dll</tt> from the latest version of the source (http://www.ode.org/; make sure to enable trimesh)

=== Running ===

Double-click on the <tt>OpenSim.exe</tt> executable file in the <tt>bin</tt> directory. This will start up OpenSim in standalone mode.

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 "<tt>chmod 777 *</tt>" from the <tt>bin</tt> directory solves this.

Physics can be invoked by adding the appropriate line to the [Startup] section of <tt>OpenSim.ini</tt>. For ODE, that would be:

physics = OpenDynamicsEngine

You can also add a command line option to a shortcut, or run from a command prompt with:

-physics=OpenDynamicsEngine

==Linux/Mac OS X==

=== Subversion Repository ===

To check out the latest revision:

svn co svn://opensecondlife.org/opensim/trunk opensim.new/trunk

Note: The <tt>libopenjpeg-libsl-...so</tt> 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.

Note to Mac OS X users: 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.

=== Building (Mono) ===

For revisions 1657 and above:

cd opensim.new/trunk

mono bin/Prebuild.exe /target nant
nant -buildfile:OpenSim.build

Earlier revisions (before 1657) require you to rerun prebuild again after the first build, and then build again:

cd opensim.new/trunk

mono bin/Prebuild.exe /target nant
nant -buildfile:OpenSim.build

mono bin/Prebuild.exe /target nant
nant -buildfile:OpenSim.build

==== Physics ====

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.

===== Open Dynamics Engine (ODE) =====

As installed from svn, ODE does not work on all platforms. If you get an ODE-related crash, and/or a libode.so not found type of error, you will need to build libode from source.

Remove <tt>libode.so</tt> from the <tt>./bin</tt> folder. (Note that subsequent svn updates may replace it again; best fix is to copy your built <tt>libode.so</tt> to <tt>bin</tt>). Do NOT remove <tt>ode.net.dll</tt>! Download the latest source packages from http://www.ode.org/. When compiling, make sure to use the following configure options:

--with-trimesh=gimpact
--enable-shared

Make sure the configure script confirms these choices, and always compile with single precision (I believe that's the default). Try <code> make -k </code> if you get errors relating to drawstuff, test*, or openGL. <code> make install </code> should put <tt>libode.so</tt> in the proper place (usually <tt>/usr/local/lib</tt>), and it should be seen by opensim (<tt>ode.net.dll</tt>)

=== Running (Mono) ===

cd bin
mono OpenSim.exe

to invoke ODE, add the option:
-physics=OpenDynamicsEngine

or add <code> physics = OpenDynamicsEngine </code> to the [Startup] section of <tt>OpenSim.ini</tt>. Same deal for other physics engines, when available.

OpenSimulator:0.5 Release Target Discussion

2007-09-07T06:14:57Z

MW1:

==Suggested Goals==

== ODE/ Physics==

*I respectfully and self-servedly recommend ODE support as a core feature of 0.5.

*Even though there are still legitimate questions about ODE's stability, it works well enough already to get ppl excited. Most of the work for the core team will transport to any other physics plugin, ie bullet or physx.

*If there is still a strong desire to completely redesign the physics interface, let's bite the bullet and do it. A world without physics is like -- well, a world without photons!

==New Backend Protocol (OGS 2)==

 

== As part of the new protocol, overhaul the "commsmanager"==

*A lot of the functions currently in there, needs moving out. Like most of the Caps handling needs to be moved to the backend servers (possible with a dedicated Caps Manager server, like LL seem to have).

*Inventory handling should move to a module. As should Xfer uploads.

== Rewrite Asset Cache/Server==

 

== Improve the management of client updates==

* Use a "interest list" for each connected client, so they only get updated about prims/objects that are in range (or they need to know about).

* Combine objects (parts) into single packets, rather than sending a separate packet for each prim as currently happens.

== Finish implementing the ll functions for scripting. ==

 

== Improve UDP network code (ClientStack) ==

 

== Clean up the IClientAPI interface ==

 

== Start to think more about security ? (most likely will not happen until a later version)==

* Add security sinks in the "region to region" .Net remoting process.

* Check for security wholes in scripting engine.

== Tighter integration of DataStore into the core ==
