This document is mostly complete and has been tested a number of times on bare metal systems. It is expected (and hoped) that developers will improve and refine this process over time - there are still some rough edges and things will change as new versions of software become available.

Step 1. Install Requirements

Required software:

Autobuild

Open a terminal and install autobuild using Python's pip command: 

pip install git+https://bitbucket.org/lindenlab/autobuild.git@v3

Intermediate Check

Confirm things are installed properly so far by typing the following in a terminal: 

cmake --version
python --version
git --version
autobuild --version

If everything reported sensible values and not "Command not found" errors, then you are in good shape! If the autobuild command is not found then you may need to add your python installation's Scripts directory to your system path.

Step 2. Checkout Code

Viewer

Open a terminal and checkout the viewer source code: 

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

Build Variables

See Building the Viewer with Autobuild#Select Build Variables.

Step 3. Configure

Switch to the viewer repository you just checked out and run autobuild configure: 

cd viewer
autobuild configure -c RelWithDebInfoOS -A 64

The -c argument determines which build configuration to create, generally either RelWithDebInfoOS or ReleaseOS. You can omit the option if you set the AUTOBUILD_CONFIGURATION environment variable to the one you want. -A may be either 64 or 32, depending on which you intend to build. You can omit that option if you set the AUTOBUILD_ADDRSIZE environment variable accordingly.

Please be patient: the autobuild configure command silently fetches and installs required autobuild packages, and some of them are large.

Step 4. Build

When that completes, you can either build within Visual Studio or from the command line

Autobuild Options

For help on configure options, type: 

autobuild configure --help

The BUILD_ID is only important for a viewer you intend to distribute. For a local test build, it doesn't matter: it only needs to be distinct. If you omit --id (as is typical), autobuild will invent a BUILD_ID for you.

For the Linden viewer build, this usage: 

autobuild configure [autobuild options]... -- [other options]...

passes [other options] to CMake. This can be used to override different CMake variables, e.g.: 

autobuild configure [autobuild options]... -- -DSOME_VARIABLE:BOOL=TRUE

The set of applicable CMake variables is still evolving. Please consult the CMake source files in indra/cmake, as well as the individual CMakeLists.txt files in the indra directory tree, to learn their effects.

Command Line Builds

In bash, initialize your tools environment by running: 

eval $(autobuild source_environment)

That only needs to be done once per bash session.

Build by running: 

autobuild build --no-configure  -c <CONFIGURATION> -A 64

the resulting viewer executable will be at: 

build-vc150-64/newview/<CONFIGURATION>/secondlife-bin.exe

Building in Visual Studio

Configure your build to run in attended mode: 

autobuild configure -c <CONFIGURATION> -- -DUNATTENDED:BOOL=FALSE
  • Open the generated Visual Studio solution file build-vc150-64/SecondLife.sln
  • Select Release or RelWithDebInfo from the configuration dropdown. (Debug is unmaintained. It would probably fail with perplexing errors.)
  • Select your starting project, if desired
  • Right-click on "secondlife-bin" in the Solution Explorer and select "Build"

When the build completes (hopefully without errors) run it by pressing Control-F5
