Say Hello with EEROS

Preparation

Setup an development environment as desribed here
Start KDevelop
Create a new C++ project:
1. Project → New from Template…
2. Choose Standard/Terminal as project type and type a project name (e.g. test-project).
3. Create the project by clicking Finish
4. Create the build configuration. It is recommended to put the target architecture in the name of the build folder. Put the location where EEROS is installed in the “Installation Prefix” field. Important: make sure that this is the location where you have installed EEROS (see Compiler EEROS). If EEROS is installed globally leave this field blank (not recommended).
5. Check the build sequence on the left bottom of Kdevelop. “eeros-framework” must be before the new project (in this example “test-project”).
6. Build the project with the build button.

Say Hello World with EEROS

Copy the following code into “main.cpp”

#include <iostream>
#include <eeros/logger/Logger.hpp>
#include <eeros/logger/StreamLogWriter.hpp>
 
int main() {
	using namespace eeros::logger;
 
	StreamLogWriter w(std::cout);
	Logger log;
 
	log.info() << "Hello, EEROS";
 
	return 0;
}

Open CMakeLists.txt file, delete the text written on it and copy the following:

cmake_minimum_required(VERSION 2.8)
 
project(test-project)
 
find_package(EEROS REQUIRED)
include_directories(${EEROS_INCLUDE_DIR})
link_directories(${EEROS_LIB_DIR})
 
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
 
add_executable(test-project main.cpp)
target_link_libraries(test-project eeros)

(Note 1: “test-project” is the name of the dummy-project created for the example. Put your project name where “test-project” is. Note 2: This file is in the project folder. e.g. /home/abajric/work/test-project)

Build the project by clicking on the “Build” button up, on the left.

Run the Hello World Program

Open a terminal
Navigate to the build folder of your project (e.g. cd /home/abajric/work/build-test-project-x86-64)
Run the program with the command: ./testproject
