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). This is not a theoretical problem, this script has caused damage to unwary users already.

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_BUILD_DIR variables (modifying the USE_* and TUNE_FLAGS variables is safe).


#!/bin/bash

# make-SL v1.86 (c)2007-2008 Henri Beauchamp. Released under GPL license v2:
# http://www.gnu.org/licenses/gpl.txt

######## THIS IS QUICK'N DIRTY ALPHA SOFTWARE. USE AT YOUR OWN RISKS ! ########
###############################################################################

###############################################################################
# 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 the client will be built into the TEMP_BUILD_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 a (no less customized but yet more standard)
# Mandriva 2007.1 distro.
# 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/SL2"
# Where to build the client:
export TEMP_BUILD_DIR="$PATH_TO_SOURCES/build"

# You may add tune flags here, to optimize the code for your processor.

# BEWARE: because of a bug in the v1.17.2.0 SConstruct file, you MUST keep at
# least an -O2 flag in the TUNE_FLAGS, to avoid getting a very slooooow client...
# This problem was apparently fixed in v1.17.3.0.
