Revision as of 10:28, 28 March 2011

The following table lists libraries and other third party dependencies used in constructing the Second Life Viewer.

Most of these (all the open source ones) should be available as prebuilds packaged by and for use with Autobuild.

Anywhere that the following disagrees with the autobuild.xml file in the viewer source, that file is correct.

The license information here is incomplete... I am still verifying and updating the license information.

LL
This repository is internal to Linden Lab.
M
This library is available under multiple licenses; the license shown is the one under which the Second Life Viewer Project is using it. See sources for details of alternatives.
B
This library is available under a license substantially similar to the traditional BSD license. See sources for details.

Redistribution

Some files in the SL installation can't be freely redistributed. This means it's not possible to simply package and offer for download a modified viewer: some files must not be redistributed.

This page documents the licenses and redistribution requirements of various files used by the viewer.

Windows

These are the files that need to be shipped with the Windows version

Runtime

Microsoft components. It's not yet known whether they're redistributable.

  • dbghelp.dll: Redistributable
  • msvcp71.dll: C++ Runtime Library, redistributable -viewer now using msvcp80.dll when compiled with VC2005
  • msvcr71.dll: C Runtime Library, Redistributable -viewer now using msvcr80.dll when compiled with VC2005

FONTS

Meta font software files

From the Readme.txt 

The Meta font software files contained in this folder are the
copyrighted property of FSI FontShop International ("FSI") and are
licensed by FSI solely for use by Linden Research, Inc. and by
residents or users of Second Life in the Second Life environment,
subject to the Second Life Terms of Service.  These Meta font software
files may not be copied by residents or developers of Second Life or
used by them for any other purpose whatsoever.
  • MtBkLfRg.ttf
  • MtBdLfRg.ttf

NOTE: These files must be replaced for an true opensource build

FMOD

FMOD sound library. Free for non-commercial projects. A commercial license will be needed for a commercial viewer.

From the README in the package: 

The fmod.dll file may be redistributed without the authors prior permission, 
and must remain unmodified.  The use of dll 'static linking' tools that aim
to hide the fmod library are forbidden.

Mozilla

The Gecko engine is MPL/GPL/LGPL licensed, which makes it redistributable.

  • app_settings/mozilla
  • freebl3.dll
  • gksvggdiplus.dll
  • js3250.dll
  • nspr4.dll
  • nss3.dll
  • nssckbi.dll
  • plc4.dll,
  • plds4.dll
  • smime3.dll
  • softokn3.dll
  • ssl3.dll
  • xpcom.dll
  • xul.dll

Kakadu

JPEG2000 library. Not redistributable. OpenJPEG is an alternative library that is redistributable

  • llkdu.dll

Starting with Viewer 2.5, llkdu.dll has been phased out. The libkdu.a and kdu.lib are still not redistributable but can be built from the toolkit provided by Kakadu under a license. How to build a viewer with such a library is documented in KDU Implementation.

OpenSSL

SSL library. Redistributable.

  • libeay32.dll
  • ssleay32.dll

Vivox

Vivox is the component that provides the voice functionality.

  • SLVoice.exe: Voice daemon. Not redistributable
  • SLVoiceAgent: Exact purpose unknown. Not redistributable
  • alut.dll: OpenAL, by Creative Labs. Redistributable.
  • ortp.dll: oRTP project, LGPL. Redistributable.
  • srtp.dll: Secure RTP?
  • vivoxsdk.dll: Vivox Communications API. Not redistributable
  • wrap_oal.dll: OpenAL32 by Creative Labs. Redistributable.

Unknown Libraries
