== Where to get Vertebra The source code is always available via Git: $ git clone git://github.com/engineyard/vertebra.git $ cd vertebra $ git submodule init $ git submodule update When switching between branches you need to remember to update the submodules. So to checkout the 0.4.0 tag to a branch you'd do this: $ git checkout -b v0.4.0 0.4.0 $ git submodule update Then when you went back to master you'd do this: $ git checkout master $ git submodule update == Dependencies We have provided a script (deps.sh) that installs some dependencies in /opt/local/vertebra: * Erlang OTP (R12B-5) * ejabberd (2.0.2) * erlsom (1.2.1) The script also installs the following gems using the gem command found on your PATH: * rspec * open4 * thor * rr * hoe The following dependencies are not installed: * expat (most systems have this) * gcc (most systems have this, Macs need to install Xcode) * iconv (glibc systems have this, only needed for ejabberd mod_irc) * make (most systems have this, Macs need to install Xcode) * glib (most linux systems have this, needed for loudmouth) * loudmouth (see note below) * loudmouth-ruby * openssl (most systems have this) * ruby * rubygems * wget OR curl (this includes most Macs and Linux machines) * zlib (most systems have this) === Loudmouth The ruby agent library requires the latest versions of both the loudmouth library and the loudmouth-ruby bindings in order to work properly. As of this writing the latest version of loudmouth is 1.5.0. It is available at: http://engineyard.github.com/loudmouth/download/loudmouth-1.5.0.tar.gz Similarly, the latest version of the bindings is 0.3.0. They are available at: http://engineyard.github.com/loudmouth/download/loudmouth-ruby-0.3.0.tar.gz == Installation If you are installing from git you need to run this command to set up the build system: $ autoreconf --install && autoreconf Then to install everything: $ ./deps.sh -a $ ./configure && make && make install What is installed can be broken down into three categories: vertebra libraries, and vertebra actors. ==== Vertebra Libraries * vertebra-rb -- Core agent library for ruby. * vertebra-erl -- Core agent library for erlang and core vertebra services. ==== Vertebra Actors * vertebra-gemtool -- Actor for managing ruby gems. * vertebra-xen -- Actor for accessing Xen slice information.
