This is Galera replication - Codership's implementation of the write set
replication (wsrep) interface (https://github.com/codership/wsrep-API).
The software and other files in this directory unless otherwise noted

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

Optional:

• Asio C++ library devel package (http://think-async.com/)

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, clone
https://github.com/codership/mysql-wsrep into some directory (hereafter
<MYSQL_DIR>) and run build script from this directory (hereafter <GALERA_DIR>):

$ cd <MYSQL_DIR>
$ git clone --single-branch --branch 5.6
https://github.com/codership/mysql-wsrep.git
$ cd <GALERA_DIR>
$ MYSQL_SRC=<MYSQL_DIR>/mysql-wsrep ./scripts/mysql/build.sh -b -s -o -t

After successful build, demo package can be found under scripts/mysql.

BUILDING on Ubuntu 16.04

1. apt-get install libasio-dev check scons libboost-program-options-dev
   libboost-dev libssl-dev

Then proceed as described above.

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 proceed as described above.
