Codership Oy http://www.codership.com <info@codership.com> This is Galera replication - Codership's implementation of the write set replication (wsrep) interface (https://launchpad.net/wsrep/). The software and other files in this directory unless otherwise noted are distributed under GPLv2, see COPYING for details. BUILDING - general Build Requirements: * Scons build system http://www.scons.org/ * Check unit test library http://check.sourceforge.net/ * Boost devel package http://www.boost.org/ * OpenSSL devel package To compile, in Galera root directory do either: $ scons (default optimized build) or $ ./scripts/build.sh (see ./scripts/build.sh --help for information on options) To build MySQL/Galera demo distribution, branch lp:codership-mysql into some directory (hereafter <MYSQL_DIR>) and run build script from this directory (hereafter <GALERA_DIR>): $ cd <MYSQL_DIR> $ bzr branch lp:codership-mysql $ cd <GALERA_DIR> $ MYSQL_SRC=<MYSQL_DIR>/codership-mysql ./scripts/mysql/build.sh -b -s -o -t After successful build, demo package can be found under scripts/mysql. BUILDING on CentOS/RHEL 5 CentOS/RHEL by default uses a very old version of GCC and a likewise ancient version of BOOST that lacks important features. In order to build Galera on CentOS/RHEL one needs to: 1) Install gcc44 and gcc44-c++ packages and set CC and CXX variables accordingly: # yum install gcc44 gcc44-c++ # export CC=gcc44 # export CXX=g++44 2) Remove standard boost and boost-devel packages (if present) 3) Install boost141-devel package: # yum install boost141-devel 4) Make link from /usr/include/boost to /usr/include/boost141: # cd /usr/include # ln -sf boost141/boost boost 5) Install scons check-devel openssl-devel # yum install scons check-devel openssl-devel Then proceeed as described above.
