## Installation

The ETSI ITS protocols project builds and tests regularly on the following platforms:

  - Linux (Ubuntu)

### Using Vagrant

Pre-requisites on your host machine:
- Install [Virtualbox](https://www.virtualbox.org/manual/ch01.html)
- Install [Vagrant](https://www.vagrantup.com/intro/getting-started/)
- Credentials to access [ETSI forge](https://oldforge.etsi.org/!/#)
    - Set the environment variable USERNAME to your ETSI OEL account user name
    - Set the environment variable PASSWORD to your ETSI OEL account password

Procedure:
- On your host machine, open a command line session (PuTTY, DOS window...)
- From the ETSI ITS protocols project, clone the Vagrant folder
- In the file Vagrantfilem, odify the tag config.vm.provision replacing <username> & <password> strings by your ETSI credentials
- In the Vagrant folder, execute the following commands:

```sh
$ vagrant up --provider virtualbox --provision
...
```

NOTE The creation and the installations will take some time to achieve
- Stop vagrant virtual machine

```sh
$ vagrant halt
...
```

- Update the file 'Vagrantfile' to match with your networks configuration
- Re-start the vagrant virtual machine and log to to the machine

```sh
$ vagrant up
...
$ vagrant ssh
```

- Switch to the next clause (Usage)

NOTE The user password is vagrant.


### Using Docker

Pre-requisites on your host machine:
- Install Virtualbox
- Install Docker

Procedure for a Windows host machine:
- On your host machine, open a the Docker Quickstart Terminal
- On your host machine, clone the ETSI ITS protocols project. NOTE that only Docker folder and .jenkins.sh script file are required
- From the ETSI ITS protocols project root directory, execute the following commands:

```sh
$ ./.jenkins.sh
...
```

NOTE The creation and the installations will take some time to achieve
- Start the container

```sh
$ ./docker/run-container.sh
...
```

- Switch to the next clause (Usage)

- Download and follow the steps to install Eclipse plugins for TITAN, accessible [here]{https://www.eclipse.org/downloads/download.php?file=/titan/Eclipse_installationguide.pdf}
- Open the workspace_titan
- Create a new TITAN project (e.g. Its_autoInterop)
<TODO>

Procedure in TITAN command line:
- Open several SSH session (PuTTY...)
- Change to the directory ~/dev/STF525_Its/src/AtsCAM/objs

- The log files are located in ../logs folder. You can edit them using any editor or using the Eclipse TITAN log plugins


## Rebuild Wireshark with support of ETSI ITS Protocols

A specific version of Wireshark, based on official version 2.6.x, is available [here](https://github.com/YannGarcia/wireshark-for-ITS.git).

The following Pre-requisites applies to build it:
- Your machine is installed followimg one of the installation method describes in the previous clause
- Your are logged as 'etsi' or 'vagrant' user

The following procedure applies to build it:
- Open a SSH session (PuTTY...)
- Change to the directory ~/frameworks
- Execute the following comands to clone the project and switch to the branck

```sh
$ git clone https://github.com/YannGarcia/wireshark-for-ITS.git wireshark-for-ITS
$ git checkout ITS_Protocol_Support
...
```

- Create a folder ~/frameworks/wireshark-build
- Change to this folder
- Generate makefiles executing the following command

```sh
$ cmake ../wireshark-for-ITS
...
```

- Add specific compiler options to the file epan/dissectors/CMakeFiles/dissectors.dir/flags.make:
    - Find the variable C_FLAGS
    - Append at the end the following compiler options: "-Wno-unused-const-variable -Wno-unsued-function "
- Build Wireshark/tshark executing the following command

```sh
$ make
```

- After the build, binaries are located in ~/frameworks/wireshark-build/run folder
- To distinguish this version of Wireshark from the others, a development tag 'ETSI ITS Protocols' is displayed on the GUI version
