LibreMetaverse

LibreMetaverse is a fork of libOpenMetaverse which in turn was a fork of libSecondLife, a library for developing Second Life-compatible virtual world clients. LibreMetaverse returns the focus to up-to-date Second Life and OpenSim compatibility with an eye to performance, multi-threading, and memory management.

Simple installation procedure

Linux/macOS

• Make sure you have at least dotnet installed, with a valid net5.0/net6.0 SDK and runtime available!

• This update includes a solution file to skip the GUI applications (which will run only under Windows anyway). Use LibreMetaverse.ReleaseNoGUI.sln instead

• From the root, run dotnet restore LibreMetaverse.ReleaseNoGUI.sln. You should get some errors regarding missing Windows libraries; that's ok, you can ignore those, they're to be expected since Linux/macOS do not include such libraries. Some test applications are Windows-only.
  If all goes well, you should now have all dependent packages properly installed.

• From the root, run dotnet msbuild LibreMetaverse.ReleaseNoGUI.sln, and enjoy the superfast Roslyn compiler at work 😄 It should finish after a few minutes, depending on the speed of your machine.

• Your binaries will be under ../bin/net5.0 or ../bin/net6.0 (there might be a few more directories under ../bin), depending on what runtimes you have installed on your system. Make sure you cd to the correct directory depending on the runtime you have, and then search for all your binaries there: they should be normal-looking executable files (with the x attribute set) and having the name of the appropriate test application (e.g. TestClient for the interactive testing tool).

• Unlike OpenSimulator, you don't need to launch the binaries with Mono, they're directly executable; the dotnet chain already embeds the small runtime that allows .NET apps to run natively on whatever operating system you've got.

Windows

For Windows, you should use the default LibreMetaverse.sln, just as before (untested). For command-line compilation under Windows, if you wish to skip the GUI applications, the instructions are the same as above. Use the default LibreMetaverse.sln if you wish to install those as well.

GUI support under Linux/macOS

Currently unavailable, although there are some reports that this might be possible using a Windows emulator, such as Mono itself, or possibly Wine. This will require some project configuration changes, and was not tested!

Note: end-of-life support for .NET 5.0

Microsoft is dropping support for .NET 5.0 as of May 2022, so you should consider using .NET 6.0 instead (or, if you're wild, you can test the prerelease of .NET 7.0). The code runs flawlessly on .NET 6.0 as well (Windows GUI version untested)
