Return to Compiling the viewer (Linux)

Automated libraries and headers adjustments, compilation and packaging


Here is a bash scripts (for v1.20 and earlier viewers: for v1.21 and later, please see cmake-SL) that could save you a lot of time... It basically does all what is needed to automatically build and package a viewer in Linux.

IMPORTANT NOTE:

This script includes instructions which have the potential to remove MANY files on your system should you modify it without understanding exactly what it does (i.e. rm -rf $VARIABLE/ where entire portions of your filesystem *will* be deleted without warning).

Although some basic checks are done to avoid removing an entire home directory, or even the root tree, this script is not meant to be tweaked without a very good knowledge of bash scripting. It is therefore highly recommended that you use it without modifying the PATH_TO_SOURCES and TEMP_DIR variables (modifying the USE_* and TUNE_FLAGS variables is safe).

# BEWARE: this script is meant to compile a -personal- SL client. It is -NOT- #
#         suitable to build client versions meant for public release, because #
#         non-open source code is packaged by this script (e.g. libkdu).      #
###############################################################################

# This bash script is aimed at easying up the build process of a SL client.
# It does not cover building it with custom/system openjpeg, elfio or fmodapi
# (we use the provided libraries).
# You may enable or disable the use of your system's library by editing
# the USE_SYSTEM_* variable ("yes" --> use the system library, "no" --> use
# LL's provided ones).
# The script also takes care of updating properly the viewer_manifest.py script
# accordingly, so that you (should) end up with a properly packaged client.

# To use this script, simply make it executable (chmod +x make-SL) and
# put it into /usr/local/bin (or any other directory in your PATH).
# Then, download the slviewer-src-*.tar.gz, slviewer-linux-libs-*.tar.gz,
# slviewer-artwork-*.zip and fmodapi*.tar.gz archives, and finally, invoke
# make-SL as follow:
#   make-SL path_to_archives  (example: make-SL ~/downloads)
# or simply:
#   make-SL
# when invoking from the directory where the archives are.
# The sources will be installed into the PATH_TO_SOURCES directory,
# and temporary files stored into the TEMP_DIR directory.
# The packaged build will be moved to your home directory.
# If you want to retry a compilation after fixing something manually and
# don't want make-SL to start all over again, overwriting everything,
# you may invoke it with the --retry option, like this:
#   make-SL --retry
# This script has been tested by the author, on a (very customized)
# Mandrake 10.2 distro, and on (less customized but yet not standard)
# Mandriva 2007.1, 2009.0 and 2010.0 distros.
# Tested with SL v1.17, v1.18, v1.19 & v1.20 sources.

# Where the sources of the client will be held (defaults to "./linden"):
PATH_TO_SOURCES="/usr/src/SL"
# Where to store temporary files:
TEMP_DIR="/usr/tmp/$USER"

# This problem was apparently fixed in v1.17.3.0.
