Installing the required dependancies

The Second Life Viewer has a number of compile/link dependancies on external libraries which need to be put in place first. The Second Life Viewer is not a trivial build, and experience with building large software packages will help you greatly - but don't be daunted, it should be simple once the dependancies are in the right place the first time.

Paths and package names given here are based on Ubuntu 6.06 and may vary according to your Linux distribution.

Prerequisites

  • You will need the SCons build tool [package: scons] and the GCC 3.4 C/C++ compiler [package: g++-3.4]; other GCC versions are not well-tested.

Copy headers and libraries into the source tree

Here is a guide to the sequence of shell commands needed to copy the needed headers and libraries into the Second Life Viewer source tree for building. Actual paths to system headers may vary according to Linux distribution.

  • ${SLSRC} refers to the top-level directory of the Second Life Viewer source tree.
  • ${OPENJPEG} refers to the top-level directory of your completed OpenJPEG build.
  • ${FMOD} refers to the top-level directory into which you unpacked FMOD 3.
  • ${ELFIO} refers to the top-level directory of your completed ELFIO build.

cp -a /usr/include/apr-1.0/ ${SLSRC}/libraries/i686-linux/include/apr-1

mkdir ${SLSRC}/libraries/i686-linux/include/expat
cp -a /usr/include/expat*.h ${SLSRC}/libraries/i686-linux/include/expat/

mkdir ${SLSRC}/libraries/i686-linux/include/zlib
cp -a /usr/include/zlib*.h ${SLSRC}/libraries/i686-linux/include/zlib/

mkdir ${SLSRC}/libraries/i686-linux/include/openjpeg
cp ${OPENJPEG}/libopenjpeg/openjpeg.h ${SLSRC}/libraries/i686-linux/include/openjpeg/
cp ${OPENJPEG}/libopenjpeg.a ${SLSRC}/libraries/i686-linux/lib_release_client/

cp ${FMOD}/api/inc/* ${SLSRC}/libraries/i686-linux/include/
cp ${FMOD}/api/libfmod-3.75.so ${SLSRC}/libraries/i686-linux/lib_release_client/

mkdir ${SLSRC}/libraries/i686-linux/include/ELFIO
cp ${ELFIO}/ELFIO/*.h ${SLSRC}/libraries/i686-linux/include/ELFIO/
cp ${ELFIO}/ELFIO/libelfio.so ${SLSRC}/libraries/i686-linux/lib_release_client/

mkdir ${SLSRC}/libraries/i686-linux/include/jpeglib
cp -a /usr/include/j*.h ${SLSRC}/libraries/i686-linux/include/jpeglib/
touch ${SLSRC}/libraries/i686-linux/include/jpeglib/jinclude.h

mkdir ${SLSRC}/libraries/i686-linux/include/llfreetype2
cp -a /usr/include/freetype2/freetype/ ${SLSRC}/libraries/i686-linux/include/llfreetype2/
cp -a /usr/include/ft2build.h ${SLSRC}/libraries/i686-linux/include/llfreetype2/freetype/

cp -a /usr/include/atk-1.0 ${SLSRC}/libraries/i686-linux/include/
cp -a /usr/include/gtk-2.0 ${SLSRC}/libraries/i686-linux/include/
cp -a /usr/lib/gtk-2.0/include/* ${SLSRC}/libraries/i686-linux/include/gtk-2.0/
cp -a /usr/include/glib-2.0 ${SLSRC}/libraries/i686-linux/include/
cp -a /usr/lib/glib-2.0/include/* ${SLSRC}/libraries/i686-linux/include/glib-2.0/
cp -a /usr/include/pango-1.0 ${SLSRC}/libraries/i686-linux/include/

if your GTK is fairly recent and thus needs Cairo: 

cp -a /usr/include/cairo/* ${SLSRC}/libraries/i686-linux/include/

Compiling

$ cd indra
$ scons DISTCC=no BTARGET=client BUILD=release

  • The resulting unstripped binary is newview/secondlife-i686-bin

Running from inside the tree

  • preparing to run 'in-tree'
    • ensure you have indra/newview/app_settings/static_*.db2 - if not, you'll find it in the 'binary-common' package.

$ cp ../../scripts/messages/message_template.msg app_settings/

  • running it!

$ ( cd newview && LD_LIBRARY_PATH=../../libraries/i686-linux/lib_release_client:${LD_LIBRARY_PATH}:/usr/local/lib  ./secondlife-i686-bin )

Packaging the client

This doesn't work 'out of the box' as an automated process right now.
