How to compile Percona Server with XtraDB 5.5 for ARM ( armhf )

To make Percona run on armhf architecture there are only small changes need to be applied.

I had a rough time getting a Percona run in a chrooted, bootstrapped Debian running beside Android on my previous phone, but it’s now done.

Get the latest code from Percona sources1, for me, it was 5.5.29-rel29.4 therefore I’ll write the docs for this version.

#!/bin/bash

cd /usr/src
wget http://www.percona.com/redir/downloads/Percona-Server-5.5/Percona-Server-5.5.29-29.4/source/Percona-Server-5.5.29-rel29.4.tar.gz
tar xzf Percona-Server-5.5.29-rel29.4.tar.gz
wget http://pastebin.com/raw.php?i=QXQNDbtc -OPercona-Server-5.5.29-rel29.4.armhf.patch
cd Percona-Server-5.5.29-rel29.4
patch -p0 < ../Percona-Server-5.5.29-rel29.4.armhf.patch
cmake . -DCMAKE_BUILD_TYPE=RelWithDebInfo -DBUILD_CONFIG=mysql_release -DFEATURE_SET=community -DWITH_EMBEDDED_SERVER=OFF

That’s it. The pastebin code is mine, I’ll copy it here as well:
