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:

svn://openmv.org/opensim/trunk

Building

2. In the top-level directory, run the 'runprebuild.bat' 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.

Running

Double-click on the OpenSim.exe executable file in the 'bin' 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 "chmod 777 *" from the bin directory solves this.

Linux

Subversion Repository

To check out the latest revision:

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

Note: The libopenjpeg-libsl-...so 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.

Building (Mono)

cd opensim.new/trunk

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

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

(Yes, you must rerun the prebuild again after the first build, and then build again!)

Running (Mono)

cd bin
mono OpenSim.exe

Binary releases

Some recent pre-compiled releases are available at OpenSim binaries. These are usually a few revs out-of-date.

There are some older versions of the binaries here
