#!/bin/bash

## Bash script for setting up a ROS/Gazebo development environment for PX4 on Ubuntu LTS (16.04). 
## It installs the common dependencies for all targets (including Qt Creator) and the ROS Kinetic/Gazebo 7 (the default).
##
## Installs:
## - Common dependencies libraries and tools as defined in `ubuntu_sim_common_deps.sh`
## - ROS Kinetic (including Gazebo7)
## - MAVROS

# ROS Kinetic/Gazebo (ROS Kinetic includes Gazebo7 by default)
## Gazebo simulator dependencies
sudo apt-get install protobuf-compiler libeigen3-dev libopencv-dev -y

## ROS Gazebo: http://wiki.ros.org/kinetic/Installation/Ubuntu
## Setup keys
sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'
sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654

##If you experience issues connecting to the keyserver, you can try substituting hkp://pgp.mit.edu:80 or hkp://keyserver.ubuntu.com:80 in the previous command.
sudo apt-get update

## Get ROS/Gazebo
sudo apt-get install ros-kinetic-desktop-full -y

## Initialize rosdep
sudo apt install python-rosdep2
sudo rosdep init
rosdep update

## Setup environment variables
rossource="source /opt/ros/kinetic/setup.bash"
if grep -Fxq "$rossource" ~/.bashrc; then 
	echo ROS setup.bash already in .bashrc;
else 
	echo "$rossource" >> ~/.bashrc;

# Install Mavros via instructions found at
# https://github.com/mavlink/mavros/tree/master/mavros#installation
sudo apt-get install python-catkin-tools python-rosinstall-generator -y

# 1. Create the workspace: unneeded if you already has workspace
mkdir -p ~/catkin_ws/src
cd ~/catkin_ws
catkin init
wstool init src

# 2. Install MAVLink
#    we use the Kinetic reference for all ROS distros as it's not distro-specific and up to date
rosinstall_generator --rosdistro kinetic mavlink | tee /tmp/mavros.rosinstall

# 3. Install MAVROS: get source (upstream - released)
rosinstall_generator --rosdistro kinetic --upstream mavros | tee -a /tmp/mavros.rosinstall
# alternative: latest source
# rosinstall_generator --upstream-development mavros | tee -a /tmp/mavros.rosinstall
# For fetching all the dependencies into your catkin_ws, just add '--deps' to the above scripts
# ex: rosinstall_generator --upstream mavros --deps | tee -a /tmp/mavros.rosinstall

# 4. Create workspace & deps
ostool merge -t src /tmp/mavros.rosinstall
wstool update -t src -j4
rosdep install --rosdistro kinetic --from-paths src --ignore-src -y

# 5. Install GeographicLib datasets:
./src/mavros/mavros/scripts/install_geographiclib_datasets.sh

# 6. Build source
catkin build

# 7. Make sure that you use setup.bash or setup.zsh from workspace.
#    Else rosrun can't find nodes from this workspace.
