-====== Say Hello with EEROS ======
-In order to be able to write your own EEROS programs or alter existing example applications, you could use any text editor and use the ''make.sh'' script on the command line. However, we recommend to use an integrated development environment.
-===== Preparation =====
-We suggest to use [[https://www.kdevelop.org/]]. Get the program with
-<code>
-$ apt-get install kdevelop
-</code>
-===== Create a New Project =====
-  - Start KDevelop
-  - Create a new C++ project:
-     - Project -> New from Template...
-     - Choose Standard/Terminal as project type and type a project name (e.g. test-project). {{ :getting_started:test-app-create-project.png?600 |}}
-     - Create the project by clicking Finish
-     - 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 [[getting_started:compile_eeros|]]). If EEROS is installed globally leave this field blank (not recommended). {{ :getting_started:test-app-builddir.png?600 |}} If your development architecture is different from your target architecture, you have to choose an toolchain file as described in [[getting_started:host_and_target|]]. You can enter this file in the field "Extra Arguments" with //DCMAKE_TOOLCHAIN_FILE=path/to/toolchain-file.cmake//.
-===== Test Program =====
-  - Copy the following code into "main.cpp" <code 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.set(w);
-  log.info() << "Hello, EEROS";
-  return 0;
-}
-</code>
-  - Open CMakeLists.txt file, delete the text written in it and copy/paste the following into it: <code cpp>
-cmake_minimum_required(VERSION 3.5.1)
-project(helloworld)
-set(CMAKE_CXX_STANDARD 14)
-find_package(EEROS REQUIRED)
-include_directories(${EEROS_INCLUDE_DIR};${EEROS_LIBUCL_INCLUDE_DIR})
-link_directories(${EEROS_LIB_DIR};${EEROS_LIBUCL_LINK_DIR})
-add_executable(helloworld main.cpp)
-target_link_libraries(helloworld eeros ucl ${CMAKE_DL_LIBS})
-</code> (Note 1: "helloworld" 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/you/work/helloworld)
-  - Build the project by clicking on the "Build" button up, on the left.
-===== Run the Hello World Program =====
-If you run your test program on the host machine continue below.
-If you want to do a crossdevelopment, you have to deploy your libraries and test program first. Go to [[getting_started:deploy|]] first before you continue below.
-  - Open a terminal
-  - Navigate to the build folder of your project (e.g. cd /home/you/work/build-x86-64)
-  - Run the program with the command: ./test-project
-{{ :getting_started:hello.png?600 |}}
-===== Use KDevelop with Existing Build Configuration =====
-If you have previously built your application manually or with the aid of the [[getting_started:install_and_setup_development_environment#Getting_the_Sources_with_a_Script|EEROS build scripts]], you can import the configuration into KDevelop as follows:
-  - Import the project by choosing the ''CMakeLists.txt'' of your project.
-  - Right click on the project and open the project configuration panel.
-  - Choose the build directory of the previously built application as your build directory
-  - Leave the entries for install directory, build type, and extra arguments empty. These settings will be fetched from the existing CMake configuration in your build directory.
-  - Click ''Ok''
-  - Build
