OpenSim Source Code
This package contains the source code for the libraries in the OpenSim API. Downloading and building the source are NOT necessary to run either the OpenSim Applications (GUI, Scripting) or the OpenSim API. Building from source is challenging and, as a non-commercial entity, we have limited resources to provide support for the build process.
