This information is for people who want to work with the source code for the viewer.

Open Source Viewer

Viewer code is hosted by GitHub using git.

Second Life Viewer

Other repositories where development for future features can be seen are listed on the Release Notes Repositories page. If you have not worked with GitHub or distributed version control you may be interested in GitHub's introductory material.

Checking out Code

To clone the current release repository:

git clone https://github.com/secondlife/viewer.git

Compiling

Per platform instructions are available in these topics:

Notes

Common compilation problems

Autobuild

Autobuild is the new Linden Lab framework to maintain and build everything, from viewer to 3rd party libraries.

Instructions:

Channels and Versions

Channels are just groupings of versions. Linden Lab uses channels to track and supply updates for Project, Beta, and Release Viewers separately.

On login, the combination of channel plus version is checked against a set of rules in the Viewer Version Management service. Within each channel, some versions are allowed and some are blocked. Viewers are blocked if they are too old, are unsafe (security issues), incompatible (the protocol has been changed in some fundamental way), or are a test version and Linden Lab only wants data from the most recent. See Viewer Integration and Release Processes for an explanation of how different versions are managed by Linden Lab.

If you are building a viewer, the Policy on Third Party Viewers requires that you set your own channel name.

See:

Channel and Version Requirements: a detailed explanation and official policy on channels and versions in Second Life, and an explanation of how to set your channel name when building.

+This information is for people who want to work with the source code for the viewer.
-Even if you don't plan to develop, just the act of downloading and compiling can uncover problems. If the version you download doesn't build on your platform, file a bug.
+==Open Source Viewer==
-== Getting the source ==
+Viewer code is hosted by [https://github.com/secondlife GitHub] using [https://en.wikipedia.org/wiki/Git git].
-The Second Life source code can be downloaded from our Subversion repository at
+* [https://github.com/secondlife/viewer Second Life Viewer]
- https://www.lindenlab.dreamhosters.com/svn/linden/release/
+Other repositories where development for future features can be seen are listed on the [https://releasenotes.secondlife.com/repositories.html Release Notes Repositories] page.

-You can download the files using your web browser, but it is recommended that you use a Subversion Client
+=== Checking out Code ===
-You can download a command line client for most operating systems at the Subversion [http://subversion.tigris.org/ web site].  If you are more comfortable with Graphical interfaces, you can also use [http://tortoisesvn.net/ TortoiseSVN], or [http://rapidsvn.tigris.org/ RapidSVN]

+Instructions:
-==== Development Environment ====
+* [[Build Viewer With Autobuild]]
-The following dev environment is what LL uses for Windows development.  There is no reason that the Second Life viewer can not be built using other enviroments, but it will take some extra work.  We should soon have instructions for building the viewer using Microsoft's Visual Studio .NET 2005 Express, which at the time of writing, was freely available.

-In the source directory, there are several empty placeholder folders for libraries which the Second Life viewer relies upon, but which Linden Lab can not ship the source. This section describes how to acquire the code, and how to install it.

-* Run Setup, and install to a convenient location (I installed to my desktop)
-* Open the installed directory, and in "Source\lib\" copy the "expat.h" and "expat_external.h" files to the "include\expat\" folder.

-== Platform notes ==
+[[Category:Compiling viewer]]
-=== Linux ===
-==== Ubuntu build notes ====
-Ubuntu 5.10 and higher uses a newer version of libc6 with a bug fix that breaks our codebase.
-If you see errors of the form:
-<code>
-    obj_dat.c:(.text+0x857): undefined reference to `__ctype_b'
-</code>
-...when you try to build our codebase then you need to enable the CTYPE_WORKAROUND.  If you use 'make' or 'dmake', add the
-following lines to your ~/.bashrc file:
-<code>
-    export SIMULATOR_CPPFLAGS="-DCTYPE_WORKAROUND"
-    export RPCSERVER_CPPFLAGS="-DCTYPE_WORKAROUND"
-    export DATASERVER_CPPFLAGS="-DCTYPE_WORKAROUND"
-    export USERSERVER_CPPFLAGS="-DCTYPE_WORKAROUND"
-    export TEST_CPPFLAGS="-DCTYPE_WORKAROUND"
-</code>
-If you use 'scons', add the follow line to your ~/.bashrc file:
-<code>
-    export SERVER_CPPFLAGS="-DCTYPE_WORKAROUND"
-</code>
-Source your ~/.bashrc, or open a new terminal, and build again.
