Build the Viewer on Windows

Visual Studio 2013 - Second Life Developer set up

This "Minimum Requirements recipe" listed below works for both local machines and VMs such as VMWare Fusion.

This document is mostly complete (see Todo sections below 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.

For Lindens Only See this page on the internal wiki for specifics of internal use.

Warning: These instructions will not work with viewer-release because they are being updated to build the 64bit (Alex Ivy) repository; for instructions that will work on other repositories, use the history tab above to view the instructions from 15 Jun 2017. Be aware that upgrading the tools on your system to those described here will mean that you will not be able to build older versions of the viewer.

Some Gotchas before we start The external package versions and bit-widths listed below have been carefully selected and tested. If you decide to install a different version of a given package (even a minor update), you are on your own. This recipe, by design, only covers development using the Cygwin shell - some commands will have to be modified if you want to use the Windows Command Prompt instead. You will need at the very least, these items before you begin: An installer for Windows 10 Pro 64bit A valid Windows Product key An installer for Visual Studio 2013 A valid license for Visual Studio 2013

Windows

• Install Windows 10 Pro 64bit using your own product key

• Keep running Windows Update (Start Menu -> All Programs -> Windows Update) until clicking on "Check for Updates" there tells you everything is up to date. Depending on the age of the install media you started with, this could take a really long time and many, many iterations.

Microsoft Visual Studio 2013 Pro

• Install VS 2013 Pro
• Note: If you don't own a copy of VS 2013 Pro, you might consider installing the Community version
  • Run the installer as Administrator (right click, "Run as administrator")
  • Uncheck all the "Optional features to install:" - they are not required

DirectX SDK

• Download and install DirectX SDK (June 2010)
  • Run the installer as Administrator (right click, "Run as administrator")
  • At the Installation Options screen, set everything except the DirectX Headers and Libs to "This feature will not be installed"

Tortoise Hg

Important: The combination of Cygwin and Tortoise Hg means it is not possible to check out or check into a repository that requires you to enter login credentials. Currently, to do this, you must switch to a Windows Command Prompt. Again, if you know how to fix this or have a suggestion for a better package to use, please let us know.

• Download and install TortoiseHg 3.2.3 (64bit)
  • Note: No option available to install as Administrator
  • Use default options (path, components etc.)

CMake

• Download and install at least CMake 3.4.3 (32bit is only option)
  • Run the installer as Administrator (right click, "Run as administrator")
  • At the "Install options" screen, select "Add CMake to the system PATH for all users"
  • For everything else, use the default options (path, etc.)

Cygwin

• Download and install Cygwin 64 (64bit)
  • Run the installer as Administrator (right click, "Run as administrator")
  • Use default options (path, components etc.) *until* you get to the "Select Packages" screen
  • Add additional packages:
    • Devel/patch
  • Use default options for everything else

Python

• Download and install the most recent version of Python 2.7 (32bit)
  • It is important to use 32-bit Python. The VMP requires it.
  • Note: No option available to install as Administrator
  • Use default options (path, components etc.) *until* you get to the "Customize Python" screen
  • Change "Add python.exe to Path" to "Will be installed on local hard drive"

Intermediate check

Confirm things are installed properly so far Open a Cygwin terminal and type: cmake --version hg --version python --version If they all report sensible values and not "Command not found" errors, then you are in good shape

Set up Autobuild and Python

• Install Autobuild
  • Open a command prompt, either cygwin or Windows Command Prompt
  • Windows: pip install hg+http://bitbucket.org/lindenlab/autobuild-1.1#egg=autobuild
  • cygwin: pip install "hg+http://bitbucket.org/lindenlab/autobuild-1.1#egg=autobuild"
    • (The quotes are important for cygwin, otherwise it thinks the # is a comment delimiter)
  • Autobuild will be installed. Earlier versions of autobuild could be made to work by just putting the source files into your path correctly; this is no longer true - autobuild must be installed as described here
• Check
  • autobuild --version
  • should report 1.1.5 or later

NSIS (Unicode)

• You must install the Unicode version here and not the one from the NSIS page
• Not required unless you need to build an actual viewer installer for distribution, or change the NSIS installer package logic itself

Test build of the Second Life Viewer

Open a Cygwin shell and create a folder to hold your work

cd /cygdrive/c
mkdir work
cd work

Check out the current viewer sources from Mercurial

hg clone https://bitbucket.org/lindenlab/viewer-release
hg clone https://bitbucket.org/lindenlab/viewer64  <= until Alex Ivy gets promoted to viewer-release

Get viewer-build-variables; see Building the Viewer with Autobuild#Select Build Variables.

Switch to the directory you just checked out and run Autobuild Configure

cd viewer-release
cd viewer64  <= with Alex Ivy
autobuild configure -c configuration -A 64

where configuration is either "RelWithDebInfoOS" or "ReleaseOS". You can omit that 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.

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

autobuild configure 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-vc120-64/newview/configuration/secondlife-bin.exe

(or of course build-vc120-32 if you choose to build a 32-bit viewer)

Building within Visual Studio

Open the VS 2013 solution file

cygstart build-vc120-64/SecondLife.sln  # or build-vc120-32 of course

• Select Release or RelWithDebInfo from the pulldown. (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"

wait...

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

Additional Tools & Settings you might need

• Tools
  • Install and set up hg hooks using instructions

    This arguably should be in the "minimum Requirements" section as it's way too easy to accidentally check in files with Windows line endings. Strongly suggest you install this.

  • Install a Visual Studio helper like WholeTomato Visual Assist for VS2013 or Workspace Whiz

    These extensions to Visual Studio add many great features. Pretty much essential for serious work.

  • Install a decent merge tool like Araxis Merge

    Many free alternatives out there but Araxis is the best (and most expensive)
