Writing EEROS Applications for the Host

You will use C++ to develop your EEROS applications. For this you need at least some knowledge of the basic language features. A good starting point might be https://www.cplusplus.com/doc/tutorial/. Minimal help can also be found under C++ for Beginners.

What do you want to do next?

Say Hello with EEROS

Create a project directory within your EEROS project directory and change into it with
```
$ mkdir hello
$ cd hello 
```

Create a text file “main.cpp” and copy the following code into it

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

Create a text file “CMakeLists.txt” and copy the following text into it:

cmake_minimum_required(VERSION 3.5.1)
project(helloworld)
 
set(CMAKE_CXX_STANDARD 14)
 
find_package(EEROS REQUIRED)
include_directories(${EEROS_INCLUDE_DIR})
link_directories(${EEROS_LIB_DIR})
 
add_executable(helloworld main.cpp)
target_link_libraries(helloworld eeros ucl ${CMAKE_DL_LIBS})

Create a build directory for your new project and change into it with
```
$ mkdir ../build-x86/hello
$ cd ../build-x86/hello
```

Build the project with

$ cmake -DCMAKE_INSTALL_PREFIX=../../install-x86 ../../hello
$ make

Continue with Working on the Host.

Use Existing Project

As an example we use the Control a Single Motor demo program.

Fetch the code of the application from within your EEROS directory with
```
$ git clone https://github.com/eeros-project/simple-motor-control.git
```

Create a build directory for your new project and change into it with

$ mkdir build-x86/simple-motor-control
$ cd build-x86/simple-motor-control

Build the project with

$ cmake -DCMAKE_INSTALL_PREFIX=../../install-x86 -DREQUIRED_EEROS_VERSION=1.2.0.0 ../../simple-motor-control
$ make

Continue with Working on the Host.
