# This script will prepare build environment with the same settings as release environment
#
# It will install two chroot environments:
#   - /home/buildbot_squeeze_i686
#   - /home/buildbot_squeeze_x86_64
# which are used for 32bit and 64bit
#
# This sctipt will also create folder /home/sources where all dependent libraries sources are
# downloading and compiling.
#
# Release builder scripts are stored in /home/sources/release-builder
# See build_all.sh script for usage details
#
# This script was tested on debian squeeze and wheezy, should work on ubuntu as well
# It wouldn't work on other distros
#
# TODO:
# - It's still required manual copying of build configuration files to /home/sources/release-builder/config
# - OSL is not set up yet

This directory contains scrips needed for automated release archive preparation

config/: storage of scons configs for different platforms

build_all.sh: script asks version to add to archive name and revision to compile,
              when script finished, there'll be 32 and 64 bit archives in current directory
              better to run this script from this directory

do_build_all.sh: uses environment variables set by build_all.sh script (or other scripts)
                 and launches compilation inside chroot environments

chroot_compile.py: runs compilation process with giver parameters in chroots
compile.py: script runs inside chroot environment and prepares archive

blender-buildenv.tar.bz2: archive, received from Ken Hughes when i've been preparing
                          new environment to make it as close to old one as it's possible

Hope all this would help you.

This directory contains different things needed for Blender builds

blender/: directory with blender's svnsnapshot

blender-build/, blender-install/: build and install directories for
                                  automated release creation

buildbot-i686-slave/,
buildbot-x86_64-slave/: buildbot slave environments for automated builds
                        (maybe it'll be better to move them to /home?)

staticlibs/: set of static libs. Mostly needed to make static linking prioretized
             under dynamic linking

release-builder/: all stuff needed for release archives preparation

Hope all this would help you.
