# Build and Deployment
This page contains steps how to set up a computer and how to successfully build and run **ReCodEx**. Most steps are listed in two variants, for Red Hat based distributions (like RHEL, Centos or Fedora) and Debian based distibutions. Before starting, make sure you have completed basic OS installation and set up, including users and logins, SSH, Git, firewall, etc.

### Repositories

**Add _testing_ repositories to Debian OS**
- Create file `/etc/apt/apt.conf` with content
```
APT::Default-Release "stable";
```
- Add testing repos to `/etc/apt/sources.list`
```
deb http://ftp.cz.debian.org/debian/ testing main contrib non-free
deb-src http://ftp.cz.debian.org/debian/ testing contrib non-free
```
- Install packages with `-t testing` option. For example
```
$ sudo apt-get -t testing install gcc
```
**Add EPEL repository to RHEL**
- See [this](https://fedoraproject.org/wiki/EPEL) for instructions.


### Installation of dependencies

Install as new version of each package as possible, so mostly Debian packages are from testing repositories and RHEL packages are the newest ones from EPEL repositories.

**Basic development tools**
- `g++`
- `cmake`
- `make`
- `git`

**Install ZeroMQ** in version at least 4.0
- Debian package is `libzmq3-dev`.
- RedHat packages are `zeromq` and `zeromq-devel`.

**Install YAML-CPP library**
