Support #491
Updated by Daniel Curtis over 9 years ago
First you MUST use GCC >= 4.8 By default, on my Raspbian version : 2013-05-25-wheezy-raspbian, gcc is on version 4.7.2. So, how to install GCC 4.8? You can't use apt-get, so to build gcc from source there is what I did : h2. Dependencies installation * Add in @/etc/apt/sources.list@ : <pre> deb-src http://archive.raspbian.org/raspbian wheezy main contrib non-free </pre> * Then install a few dependencies: <pre> sudo apt-get update sudo apt-get install lsb-release debhelper bison flex libmpfr-dev libmpc-dev zlib1g-dev libgmp3-dev sudo apt-get build-dep gcc-4.7 autoconf2.64 </pre> h2. Install GCC * Download the latest GCC 4.8 <pre> wget https://ftp.gnu.org/gnu/gcc/gcc-4.8.1/gcc-4.8.1.tar.gz -O gcc-4.8.1.tar.gz tar xf gcc-4.8.1.tar.gz </pre> * Get and apply patches <pre> wget http://anonscm.debian.org/viewvc/gcccvs/branches/sid/gcc-4.7/debian/patches/armhf-triplet.diff?view=co -O armhf-triplet.diff wget http://anonscm.debian.org/viewvc/gcccvs/branches/sid/gcc-4.7/debian/patches/gcc-multiarch-trunk.diff?view=co -O gcc-multiarch-trunk.diff cd gcc-4.8.1 patch -p2 -i ../armhf-triplet.diff patch -p2 -i ../gcc-multiarch-trunk.diff cd gcc autoconf2.64 cd ../libjava autoconf2.64 cd .. </pre> * GCC configuration <pre> cd .. mkdir obj cd obj ../gcc-4.8.1/configure --prefix=/opt/gdc --enable-shared --enable-linker-build-id --with-system-zlib --without-included-gettext --enable-threads=posix --enable-nls --enable-clocale=gnu --enable-libstdcxx-debug --enable-libstdcxx-time=yes --enable-gnu-unique-object --enable-plugin --enable-objc-gc --disable-sjlj-exceptions --with-arch=armv6 --with-fpu=vfp --with-float=hard --build=arm-linux-gnueabihf --host=arm-linux-gnueabihf --target=arm-linux-gnueabihf --enable-checking=yes --disable-bootstrap --enable-languages=c,c++ </pre> * Compilation <pre> make 2>&1 | tee build.log </pre> * Installation <pre> sudo make install </pre> * Change symbolic links, this changes your currents gcc and g++ commands to use gcc 4.8 <pre> sudo ln -s /opt/gdc/bin/gcc /usr/bin/gcc sudo ln -s /opt/gdc/bin/g++ /usr/bin/g++ </pre> h3. Verification * Commands should return GCC version 4.8 <pre> gcc -v g++ -v </pre> h2. Compile Galera So, now you have GCC 4.8 with atomic 8 bits operation! But there is a bug which prevent you to build Galera lib with "GCC 4.8":https://bugs.launchpad.net/galera/+bug/1164992 So you must use Galera revision higher than 149. At this time I used 152, but I think you safely use the latest version now. * Download Galera (>149, in this case 152) <pre> wget http://bazaar.launchpad.net/~codership/galera/2.x/tarball/152?start_revid=176 http://bazaar.launchpad.net/~codership/galera/2.x/tarball/152?start_revid=152 -O galera.tgz tar xf galera.tgz </pre> * Compilation <pre> cd \~codership/galera/2.x/ scons boost_pool=0 </pre> We move the files later. h2. Install MariaDB * Dependencies installation <pre> sudo apt-get install cmake make g++ libncurses5-dev mysql-client </pre> * MariaDB Download <pre> http://ftp.osuosl.org/pub/mariadb/mariadb-galera-5.5.40/source/mariadb-galera-5.5.40.tar.gz wget http://ftp.igh.cnrs.fr/pub/mariadb/mariadb-galera-5.5.29/kvm-tarbake-jaunty-x86/mariadb-galera-5.5.29.tar.gz tar xf mariadb-galera-5.5.40.tar.gz mariadb-galera-5.5.29.tar.gz cd mariadb-5.5.40/ mariadb-5.5.29/ </pre> * Compilation <pre> cmake -G "Unix Makefiles" -DWITH_WSREP=ON -DWITH_INNODB_DISALLOW_WRITES=1 make sudo make install </pre> * Move Galera's need file to MariaDB repository <pre> sudo cp garb/garbd /usr/local/mysql/bin/ sudo cp libgalera_smm.so /usr/local/mysql/lib/plugin/ </pre> Now just configure your database with Wsrep configuration and use it. h2.
