Compiling the viewer (MSVS2003)

The following instructions are for compiling the Second Life viewer on Windows. For other platforms, see Compiling the viewer. If you get lost, or these instructions are incomplete, email ben@lindenlab.com - I'll try to get them fixed.

Windows

Development Environment

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 environments, 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.

• Visual Studio .NET 2003 Professional
  • Microsoft Platform SDK
  • NEED NEWER DIRECTX DirectX 9.0 SDK Update (Summer 2003)
  • Set up the project globals:
    • Start Visual C++
    • Go to Tools/Options/Projects/VC++ Directories
    • Make sure that the includes and libraries paths have the DirectX SDK paths first, then the Platform SDK paths, and then the Visual C++ paths.
• ActivePython 2.3x
• ActivePerl
• Cygwin
  • When you run the cygwin setup utility make sure you have selected to install patchutil, flex, and bison (all located under "devel").

Libraries

If you have downloaded the library directory from LL, extract it, and copy the files to your code directory, maintaining the same directory structure. We have included all the libraries we can ship in this file, but we can not distribute the source to the following , and you will need to follow the instructions to acquire below:

Fmod Quicktime

In the source directory, there are several empty placeholder folders for libraries which the Second Life viewer relies upon. This section describes how to acquire the code, and how to install it. It is a good idea to install in order, as some libraries will rely on previous installs (ie, libcurl needs opensll and zlib).

Boost

• Download & extract Boost source for win32.
• Copy the "boost_X_XX_X\boost" folder to "libraries\include\".
• Run "boost_X_XX_X\tools\build\jam_src\build".
• Copy "boost_X_XX_X\tools\build\jam_src\bin.ntx86\bjam.exe" to "boost_X_XX_X\".
• Using the command prompt, build the static libraries:
  • cd linden\libraries\boost-X_XX_X\
  • set PYTHON_ROOT=C:\Python23
  • set PYTHON_VERSION=2.3
  • bjam stage
• copy "boost_X_XX_X\stage\lib\libboost_python-vc71-mt.lib" to "\libraries\i686-win32\lib_release\"

  • Right click each project in the Solution Explorer, choose properties.
  • In the C/C++ folder, choose Code Generation.
  • Change the Runtime Library to Muli-threaded.
  • Repeat for both debug and release.

  • copy the contents of "apr\include" to "libraries\i686-win32\include\apr-1".
  • in "libraries\i686-win32\include\apr-1\arch\" only the "win32" dir and "apr_private_common.h" are required.
  • copy the contents of "apr-util\include" to "libraries\i686-win32\include\apr-1".

$ cd xmlrpc-epi-0.51
$ patch -p1 < ../remove_iconv.patch
$ patch -p1 < ../excise_expat.patch
$ rm -rf expat
$ mkdir expat
$ cp $FOO expat
    Where $FOO is either
        /tmp/expat/include/* -- if you built expat recently
    or  ../../expat-1.95.8/src/lib/expat*.h -- if you haven't
    in this later case you'll need to have CVS gotten the expat
    lib, and expanded it's src.tar.gz file there

Building

• Open the \indra\indra_complete\indra_complete.sln solution in Visual Studio.
• Set newview to be the startup project.
• Build either ReleaseNoOpt (for debugging) or ReleaseForDownload (for production).
• newview.exe will be built in \indra\newview\ReleaseNoOpt or \indra\newview\ReleaseForDownload
• create a shortcut to newview, and change the start location to \indra\newview\ (all the .dll will be found there.)
