Create debian packages out of a ROS package (docker)

The dockerfile should be something like

# If amd64 architecture
# FROM osrf/ros:melodic-desktop-full-bionic

# If arm64 architecture
FROM arm64v8/ros:melodic

# uncomment ARG if you need to interact with a remote repository

How create a debian package out of Paho MQTT C

$ git clone https://github.com/eclipse/paho.mqtt.c.git
$ cd paho.mqtt.c

# Check version from Paho MQTT Cpp too
$ git checkout v1.3.1

Example to show the usage of condition variable

In addition to the good documentation provided by cppreference

I had a doubt that the mutex would be locked in the waiting cycle, but because of the condition_variable::wait() function, it actually allows other threads to access the variable while no notifi_all() method has been called.

#include <iostream>
#include <condition_variable>

Create a debian pkg out of CMakeFiles/CMakeLists.txt

The following script is meant to be used to create a debian package out of a CMake project well defined

  GNU nano 2.9.3                                                                                 build_deb_from_cmake.sh                                                                                 Modified

Having a simple debian package out of a Python script

Create a directory to store the debian folder

$ mkdir -p test_folder/DEBIAN

Create a control file inside debian folder

	#!/bin/bash
	sudo apt update
	sudo apt install docker.io
	sudo usermod -aG docker ${USER}
	su - ${USER}
	id -nG
	docker version
	docker run hello-world

	# Defines the following variables:
	#
	# GMOCK_FOUND - Found the Google Testing framework
