Otherwise, if you are a developer who wants to set up a development environment using the latest upstream code, this document is for you.
All ruby gems that our project relies on are installed locally in a sandbox via bundler (gem and bundler must already be installed). Of course, if other system-wide gems are installed that is fine too-- "bundle install" will pull in the version-specific dependencies it needs locally.
There are a few things that need to be done as root or a sudo-enabled user before we check out the Conductor repository and fire up the development server.
We rely on the system to provide some development libraries, ruby, gem, bundler and a database. Specifically for RHEL 6 or Fedora Core 16 or 17, we can grab these dependencies with:
yum install -y postgresql-server postgresql postgresql-devel ruby ruby-devel ruby-rdoc git libxml2 libxml2-devel libxslt libxslt-devel gcc gcc-c++
^^assumes using postgres as our back-end database, but we could just as well use sqlite or mysql.
This set of requirements is not unusual and should look familiar to the experienced Ruby developer. Of course, installing these libraries for another flavor of OS should also be relatively straightforward.
As previously mentioned, gem and bundler also should be available on your system but no other system-wide gems are necessary.
If you happen to be running RHEL6 or Fedora 16/17, you can download the script conductor-dev-root-prep.sh from https://gist.github.com/3178181 which installs the needed system dependencies and sets up postgres.
Otherwise, you will need to adapt the steps in the script for your particular OS.
With the above prerequisites met, setting up a development environment is as easy as cloning the repository, bundle-installing the needed gems locally, and running a few rake commands. See the OS-agnostic script conductor-dev-setup.sh from https://gist.github.com/3178181 which does just that. This script should not be run as root, rather as the non-privileged user you are going to do development with.
