EOOS Automotive for POSIX based operating systems is a C++ library for cross-platform development of applications in automotive sphere. The library is developed in C++98 programming language and supports features of C++11 programming language depending on compiler options that allows to consider wide criteria when selecting a suitable programming language on initiation step of product development.

EOOS Automotive POSIX is developed within ISO C++ standards, complied with MISRA C++:2008 and AUTOSAR C++14 Coding Guidelines, and relies on ISO 26262 that means applications based on EOOS can be used in critical and safety-related systems.

Quality of EOOS Automotive POSIX:

  • MISRA C++: 0 violations
  • Unit Tests coverage: 96%

1. How-to Build Project

EOOS is a static library for linkage with other POSIX based applications. This EOOS project based on CMake that builds the static library and installs it on an UNIX OS for being found by CMake projects of the applications.

1.1. Prerequisites on Linux

The process described below is passed on

  • Ubuntu 18.04 LTS (x86_64)
  • Ubuntu 22.04 LTS (x86_64)

and requires the next tool to be installed on it:

1.1.1. Install Git for Linux and Unix

Get Git for Ubuntu following the commands below. For other UNIX OSs following the instruction from the web-site.

$ sudo apt-get update
$ sudo apt-get install git
$ git --version
git version 2.17.1
1.1.2. Install CMake 3.10 or higher

CMake minimum required version 3.10 for EOOS project.

Download and install CMake from the web-site. Check CMake version in Terminal.

$ cmake --version
cmake version 3.10.6
1.1.3. Instal IDE and compiler for purposes that you need

EOOS is developed within ISO C++ standards and can be compiled with any compilers, which support ISO/IEC 14882:1998 standard and ISO/IEC 14882:2011 standard for new features of C++ programming language.

To debug applications we are used to using Eclipse IDE for C/C++ Developers. Compiler on Ubuntu 18.04 LTS is installed by default, and you can check it in Terminal.

$ gcc --version
gcc (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0

$ g++ --version
g++ (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0

Compiler on Ubuntu 22.04 LTS can be checked as well in Terminal

$ gcc --version
gcc (Ubuntu 11.2.0-19ubuntu1) 11.2.0

$ g++ --version
g++ (Ubuntu 11.2.0-19ubuntu1) 11.2.0
1.1.4. Install Python 3.7 or higher for automation

Check your version is not 3.7

$ python3 --version
Python 3.6.9

Install version 3.7

$ sudo apt-get install python3.7

Update Python alternatives

$ sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 1
$ sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.7 2

Configure vession 3.7 as default

$ sudo update-alternatives --config python3

Check your version is 3.7

$ python3 --version
Python 3.7.6
1.1.5. Install Pip for Python 3.7 for automation
$ sudo apt-get update
$ sudo apt-get -y install python3-pip
$ pip3 --version
pip 22.0.2 from /usr/lib/python3/dist-packages/pip (python 3.7)
1.1.6. Install GCOVR for unit tests reports generation

Install GCOVR

$ pip install gcovr
$ gcovr --version
gcovr 5.2

1.2. Obtain Git Repository

1.2.1. Create an empty directory somewhere on your disk

For instance we will create ~/REPOSITORY.

1.2.2. Clone this repository

For instance we will clone it to EOOS directory by SSH.

~/REPOSITORY$ git clone --branch master EOOS
1.2.3. Go the EOOS directory
1.2.4. Initialize and update all submodules of the repository
~/REPOSITORY/EOOS$ git submodule update --init

1.3. Source Code Build and Installation

EOOS can be executed on various systems. To standardize the building process, we put most common steps under the hood of the cross-platform script that is located in scripts/python directory.

1.3.1. Build and Installation for Developing on EOOS
~/REPOSITORY/EOOS$ cd scripts/python
~/REPOSITORY/EOOS/scripts/python$ python3 --clean --build EOOS --install --config RelWithDebInfo

None that the –config parameter can be one of Release, Debug, RelWithDebInfo, MinSizeRel, but for developing purpose we recommend to pass RelWithDebInfo.

Having done all the steps, EOOS will be installed to the /usr/local directory, and you will be able to find EOOS in by using find_package() command in your CMake project.

An example of your root CMakeLists.txt may be the next:

cmake_minimum_required(VERSION 3.10)
project(eoos-application VERSION 1.0.0 LANGUAGES CXX)


find_package(EOOS 0.11.0 REQUIRED)




set_target_properties(application PROPERTIES
    OUTPUT_NAME EoosApplication

Thus, you will build EoosApplication.exe executable file.

For more examples and fast start please see the EOOS Automotive Sample Applications repository

1.3.2. Build for Testing EOOS

This chapter must be useful for EOOS developers and CI/CD engineers, but not prohibited to be used by any other for sure.

To build the project with Unit Tests and run them, you have to execute the commands below.

~REPOSITORY/EOOS$ cd scripts/python
~REPOSITORY/EOOS/scripts/python$ python3 --clean --build ALL --run --config RelWithDebInfo
