This information is for people who want to look at the actual source code for the viewer. Just the act of downloading and compiling can uncover problems. If the version you download doesn't build on your platform, file a bug.
This information is for people who want to work with the source code for the viewer.
If you have time and skill, adding a feature that you've always wanted, or fixing a bug that most annoys you is welcome.  There is a process for uploading your changes and getting them accepted for a merge into a future release viewer.

This is the latest Viewer 2 code that LindenLab has.
Viewer code is stored in a [https://en.wikipedia.org/wiki/Git Git] repository on [https://bitbucket.org/lindenlab bitbucket], an  Open Source repository web site.
Viewer 2 source code is stored in a Mercurial (hg) repository on [http://bitbucket.org/lindenlab bitbucket], one of the main Open Source repository web sites. There are many versions there, with the ones you are most likely interested in being

You can browse the source code using an ordinary web browser, download it to your machine, or use Mercurial to manage the process for you.

One of the interesting features of the Viewer-Development branch is that you can literally watch Lindens merging bug fixes and new features into the code before your very eyes.


Another good way to browse the source code, including UML diagrams,  is using  [http://dimentox.com/snowstorm/ Doxygen].

Be sure to read [[Creating a version control repository]].
To clone the current release repository:


=== Download Source Archives (Zipfile/Tarball) ===
  <nowiki>git clone git@bitbucket.org:lindenlab/viewer.git</nowiki>
 
OBSOLETE! Linden Lab provides current and past downloads in an archived format, see the [[source downloads]] page. Be sure to get all three: source, artwork, and libraries.

OBSOLETE!
 
Linden Lab maintains a version control repository containing various (experimental) branches.
See the [[version control repository]] page for the correct repository url.
 
Subsequently, if you are using a command line, you could check out the source code with
svn checkout '''repository-url''' '''target-directory'''
For example to checkout snowglobe 1.4:
cd snowglobe-1.x-svn
svn checkout <nowiki>https://svn.secondlife.com/svn/linden/projects/2009/snowglobe/trunk</nowiki> linden
 
Note that using <nowiki>'https://'</nowiki> as opposed to <nowiki>'http://'</nowiki> is only really necessary if you are a

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

Open Source Viewer

Viewer code is stored in a Git repository on bitbucket, an Open Source repository web site.

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

Checking out Code

To clone the current release repository:

git clone git@bitbucket.org:lindenlab/viewer.git

Compiling

Per platform instructions are available in these topics:

Notes

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.
