This page covers building OpenSimulator from source code on multiple platforms.  Please help us keep this page up to date as the project progresses. If you just want to run OpenSimulator, [[Download]] and [[Configuration|run]] the binary build instead. In the most cases, you should be fine with binaries.
  
OpenSim requires either the .Net framework version 2.0, or the latest Mono. It supports the following compilers:
+
= Obtaining the Source Code =
* [http://msdn2.microsoft.com/en-us/express/aa700756.aspx Microsoft Visual C# Express Edition] (note: not Visual C++)
+
* [http://www.mono-project.com/ mono]
+
  
Note for people who just downloaded the sources from http://dist.opensimulator.org/ (the "Downloads" link on the left) be advised that some important things are missing (like MySQL template scripts). For such features, you must download using svn!
+
Check out the [[Download]] page for instructions on obtaining an OpenSimulator source release.  If you want the current development code (i.e. the Git master branch) see [[Developer_Documentation#Source_Code_Repository_Access]].

=== Subversion Repository ===
 
  
1. Get the nightly build source code from the svn repository:
+
Although this page is long, building is generally quite simple. See the BUILDING.txt file in the distribution itself for simplified instructions.
  
http://opensimulator.org/svn/opensim/trunk
+
== Requirements ==
  
2. Get 0.4.5.2 Stable version  from svn repository:
+
OpenSimulator 0.9.0.x requires either
svn co http://opensimulator.org/svn/opensim/tags/0.4.5.2-stable opensim
+
* [http://msdn.microsoft.com/en-us/netframework/cc378097 .NET Framework 4.0] on Windows
 +
* [https://www.mono-project.com/download/stable/ Mono] on Linux or Mac.  Mono 2.10.8 is the minimum version.
 +
You may also need nant tool.
  
=== 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.
+
OpenSimulator 0.9.1 (including current master) requires either
 +
* [http://msdn.microsoft.com/en-us/netframework/cc378097 .NET Framework 4.6] on Windows
 +
* [https://www.mono-project.com/download/stable/ Mono] on Linux or Mac.  Mono 5.12 is the minimum recommended version.
 +
recommend compiling with msbuild.
  
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.
+
Other platforms may have own mono distributions, or may need to compile mono on them.
  
==== Physics ====
 
  
===== Open Dynamics Engine (ODE) =====
+
Other libraries used by OpenSimulator can be found at our opensim-libs git repo.
  
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.
+
git clone git://opensimulator.org/git/opensim-libs
  
As installed from svn, ODE does not work on all platforms.  If you get an ODE-related crash, and/or an <i>ode.dll not found</i> type of error (which can occur even though the dll is present!), try using the debug version of the dll, available here:
+
You may need to compile them for your platform, in particular the unmanaged ones like Bullet or ODE native code libraries
  
http://www.squiggle.com/opensim/ode-debug.dll <br>
+
== MS Windows ==
  
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)
+
=== Supported Compilers ===
 +
* [https://visualstudio.microsoft.com/downloads/ Visual Studio Community 2017]
 +
* Or any version that does support the .Net version. At least VS2010 for versions prior to 0.91, VS2015 for 0.91 and after.
  
=== Running ===
+
=== Compiling in an IDE ===
 +
# Run "runprebuild.bat"
 +
# Open the resulting "OpenSim.sln" in Visual Studio IDE.
 +
# Select Debug or Release configuration
 +
# Menu Build -> Build Solution.
  
Recent versions of OpenSim come without an <tt>OpenSim.ini</tt> file. Copy the <tt>OpenSim.ini.example</tt> file to <tt>OpenSim.ini</tt> before making any changes.
+
===Compiling at the Command Prompt ===
 +
# Run "runprebuild.bat".
 +
# Run the resulting "compile.bat" file.
  
Double-click on the <tt>OpenSim.exe</tt> executable file in the <tt>bin</tt> directory. This will start up OpenSim in standalone mode.
+
== Linux and Other Mono Platforms ==
  
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.
+
=== Prepare to compile ===
 +
To create the several project files run on the folder opensim:
  
Physics can be invoked by adding the appropriate line to the [Startup] section of <tt>OpenSim.ini</tt>. For ODE, that would be:
+
  ./runprebuild.sh
  
physics = OpenDynamicsEngine
+
==== Compile with Nant ====
 +
On some mono versions, in particular old ones may need the use of nant to proper compile OpenSimulator, in that case just run:
  
You can also add a command line option to a shortcut, or run from a command prompt with:
+
  nant
  
-physics=OpenDynamicsEngine
+
==== Compile with xbuild ====
  
'''''Windows Vista'''''
+
On mono versions you can just use xbuild.
  
To run on Windows Vista, you must first disable Windows Firewall.  Under the new "Start" button of Vista, select "Control panel".  Then double-click "Windows Firewall".  In the window that pops up, on the left column, select "Turn Windows Firewall on or off".  You will have to give permission for this to run, then select the option "Off (not recommended)".  Click "OK" and exit from the Windows Firewall window.
+
  xbuild
  
If you have McAfee SecurityCenter, see the description below.
+
xbuild is no longer recommended on mono 5.x, but currently still works (5.12)
  
Once all the security features are disabled, right click on <tt>OpenSim.exe</tt> and select "Run as administrator".  This will pop up a window asking permission, select "Allow".  Your OpenSim server should run in a DOS-like window and accept connections.
 
  
 +
on more recent monos Release configuration may give some performance gain, but you do lose some debug capabilities.
 +
to compile Release configuration:
 +
  xbuild /p:Configuration=Release
  
'''''McAfee Security'''''
+
==== Compile with msbuild ====
 +
For Opensim 0.9.1 you can still use xbuild but Mono recommends the use of msbuild. You might need to install the package msbuild in addition to mono-complete for that.
  
McAfee Security does not allow applications to listen on ports not explicitly specified.  You have two options: 1) disable firewall protection all together, 2) enable <tt>OpenSim.exe</tt> to be able to open ports.
+
Use xbuild on the other cases.
  
''Disable firewall''
+
Recent improvements, specially on JIT runtime, justify compiling in Release configuration, but you do lose some debug capabilities.
  
Open McAfee SecurityCenter.  Select "Internet & Network".  In the lower left corner is a small link to "Configure...".  Select this.  In the right side of the window, select the bar that says "Firewall protection is enabled".  Here you can select "Off".
+
to compile with Debug configuration:
 +
  msbuild
  
''Enable <tt>OpenSim.exe</tt> to open ports''
+
to compile with Release configuration:
 +
  msbuild /p:Configuration=Release
  
Open McAfee SecurityCenter.  Select "Internet & Network".  In the lower left corner is a small link to "Configure...".  Select this.  In the right side of the window, select the bar that says "Firewall protection is enabled".  Select the "Advanced..." button.  This will pop up a new window.
+
= Configuration =
  
In the new window, on the left side, select "Program Permissions."  In the middle on the right side of the window, select the "Add Allowed Program" button.  Use the browser that pops up to find the OpenSim executable and select it.
+
See [[Configuration]].
  
Finally, select "OK" and exit the McAfee SecurityCenter window.

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.
+
 
+
Notes 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.
+
* You'll also need to install Mono.
+
* 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
+
* 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).
+
 
+
=== Building (Mono) ===
+
 
+
cd opensim
+
./runprebuild.sh
+
nant
+
 
+
If you encounter any errors while trying this, check the [[Troubleshooting]] page for help.
+
 
+
==== Physics (Unix) ====
+
 
+
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 <i>libode.so not found</i> 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>)

This page covers building OpenSimulator from source code on multiple platforms. Please help us keep this page up to date as the project progresses. If you just want to run OpenSimulator, Download and run the binary build instead. In the most cases, you should be fine with binaries.

Contents

Obtaining the Source Code

Check out the Download page for instructions on obtaining an OpenSimulator source release. If you want the current development code (i.e. the Git master branch) see Developer_Documentation#Source_Code_Repository_Access.

Building

Although this page is long, building is generally quite simple. See the BUILDING.txt file in the distribution itself for simplified instructions.

Requirements

OpenSimulator 0.9.0.x requires either

You may also need nant tool.


OpenSimulator 0.9.1 (including current master) requires either

recommend compiling with msbuild.


Other platforms may have own mono distributions, or may need to compile mono on them.


Other libraries used by OpenSimulator can be found at our opensim-libs git repo.

git clone git://opensimulator.org/git/opensim-libs

You may need to compile them for your platform, in particular the unmanaged ones like Bullet or ODE native code libraries

MS Windows

Supported Compilers
