Re: Can't launch cluster - undefined symbol: __sync_fetch_and_add_8

So, after few days i found the solution. I just missed to post it here.
I hope this can help somebody :-)
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 and it's why this error append.
I don't remember exactly why, but in my memorie it's because gcc <= 4.8 don't implemented 8 bits atomic operation on ARM.
So, how to install GCC 4.8 ?
You can't use apt-get :(
So to build gcc from source there is what i do :
Dependencies installation
Add in /etc/apt/sources.list :
Deb-src http://archive.raspbian.org/raspbian wheezy main contrib non-free
$ 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
Download GCC
$ wget ftp://ftp.uvsq.fr/pub/gcc/releases/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
Use Patchs
$ 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 ..
GCC configuration
$ 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++
Compilation
$ make 2>&1 | tee build.log
Installation
$ sudo make install
Change symbolic links
This change your currents gcc and g++ commands to use gcc 4.8
$ sudo ln -s /opt/gdc/bin/gcc /usr/bin/gcc
$ sudo ln -s /opt/gdc/bin/g++ /usr/bin/g++
Verification
Commands should return GCC version 4.8
$ gcc -v
$ g++ -v
So, now you have GCC 4.8 with atomic 8 bits operation !
But there is a bug which prevent you to build Galera lib withGCC 4.8 ... (lol)
https://bugs.launchpad.net/galera/+bug/1164992
So you must use Galera revision > 149
(At this time i used 152, but i think you safely use the latest version now)
Download Galera (>149, in this case 152)
$ wget http://bazaar.launchpad.net/~codership/galera/2.x/tarball/152?start_revid=152 -O galera.tgz
$ tar xf galera.tgz
Compilation
$ cd \~codership/galera/2.x/
$ scons boost_pool=0
We move files later.
And now just install the database (Maria DB in my case) :
Dependencies installation
$ sudo apt-get install cmake make g++ libncurses5-dev mysql-client
MariaDB Download
$ tar xf mariadb-galera-5.5.29.tar.gz
$ cd mariadb-5.5.29/
Compilation
$ cmake -G "Unix Makefiles" -DWITH_WSREP=ON -DWITH_INNODB_DISALLOW_WRITES=1
$ make
$ sudo make install
Move Galera's need file to MariaDB repositorie
$ sudo cp garb/garbd /usr/local/mysql/bin/
$ sudo cp libgalera_smm.so /usr/local/mysql/lib/plugin/
Now just configure your database with Wsrep configuration and use it :)
I hope this help somebody.
Best Regards.
