Building eCAL from source

If you want to build eCAL yourself, this tutorial may help you with that. To build eCAL, you will need a C++14 compliant compiler, such as Visual Studio 2015 or newer, or GCC 5 or newer.

Currently, we support:

• Windows 7 / 10

• Ubuntu 16.04 / 18.04 / 20.04

Repository checkout

First check out the eCAL repository and all of the submodules:

git clone git://github.com/continental/ecal.git
cd ecal
git submodule init
git submodule update

Building eCAL on Windows

Windows Dependencies

1. Download and install the build-dependencies

   • CMake (https://cmake.org)

   • Qt5 (>= 5.5 / 64-bit) (https://www.qt.io/download)

   Note

   If you have multiple Versions of Qt installed, eCAL will try to pick the latest match for your Visual Studio Version.

   If this fails (e.g. as you have copied the qt directory without properly installing it) or if you want to use a specific Qt5 Version, you may have to manually set the CMAKE_PREFIX_PATH or Qt5_DIR.

2. Optional: Install additional dependendencies

   • Python for Windows (64 Bit, Version 3.x): To build the python extensions and the documentation

   • Doxygen: To build the documentation

   • Innosetup: To create an executable Installer

Windows build

• To just compile eCAL:

  mkdir _build\complete
  cd _build\complete
  
  cmake ../.. -A x64 -DCMAKE_INSTALL_PREFIX=_install -DBUILD_SHARED_LIBS=OFF
  cmake --build . --parallel --config Release
  

  This will create a _build\complete\ directory in your eCAL root folder and build eCAL there.

• To build a complete setup:

  1. For creating a setup, you have to also build the documentation and build the debug SDK binaries.

     The batch files will compile eCAL with the MSVC 2015 Toolset to provide downwards compatibility. Thus, you will need to install:

     • The MSVC 2015 Toolset (-> v140) for your probably newer Visual Studio

     • Qt5 as msvc2015_64 (Or manually override it by setting Qt5_DIR)

     Execute the following batch files with the appropriate parameter to create the Visual Studio 2015 (v140) / 2017 (v141) / 2019 (v142) solution and build it.

     build_win\win_make_cmake.bat v140 ( / v141 / v142)
     build_win\win_make_build.bat
     

     This will create a _build\ directory in your eCAL root folder and build eCAL in two configurations, there.

  2. Run the following batch files to create an eCAL setup as .exe installer:

     build_win\win_make_setup.bat
     

     You will find the .exe installer in the _build\complete\_deploy\ directory.

  3. Optional: If you configured CMake to build the python extension by setting BUILD_PY_BINDING to ON you can create the eCAL python egg by calling

     build_win\win_make_python_egg.bat
     

     Afterwards you will find the python eCAL egg in the _build\_deploy\ directory. Install the extension by

     python -m easy_install ecal-X.Y.Z-pyX.Y.egg
     

Building eCAL on Ubuntu

Ubuntu 16.04 dependencies

1. Add the official cmake repository, as eCAL needs cmake >= 3.13:

   wget -O - https://apt.kitware.com/keys/kitware-archive-latest.asc 2>/dev/null | gpg --dearmor - | sudo tee /etc/apt/trusted.gpg.d/kitware.gpg >/dev/null
   sudo apt-add-repository -y 'deb https://apt.kitware.com/ubuntu/ xenial main'
   sudo apt-get -y update
   sudo apt-get install kitware-archive-keyring
   sudo rm /etc/apt/trusted.gpg.d/kitware.gpg
   

2. Add a ppa for protobuf >= 3.0. The following (unofficial) ppa will be sufficient:

   sudo add-apt-repository -y ppa:maarten-fonville/protobuf
   sudo apt-get -y update
   

3. Install the dependencies from the ordinary Ubuntu 16.04 repositories and the ppa we just added:

   sudo apt-get install git cmake doxygen graphviz build-essential zlib1g-dev qt5-default libhdf5-dev libprotobuf-dev libprotoc-dev protobuf-compiler libcurl4-openssl-dev
   

Ubuntu 18.04 dependencies

1. Add the official CMake repository, as eCAL needs CMake >= 3.13:

   wget -O - https://apt.kitware.com/keys/kitware-archive-latest.asc 2>/dev/null | gpg --dearmor - | sudo tee /etc/apt/trusted.gpg.d/kitware.gpg >/dev/null
   sudo apt-add-repository 'deb https://apt.kitware.com/ubuntu/ bionic main'
   sudo apt-get -y update
   sudo apt-get install kitware-archive-keyring
   sudo rm /etc/apt/trusted.gpg.d/kitware.gpg
   

2. Install the dependencies from the ordinary Ubuntu 18.04 repositories:

   sudo apt-get install git cmake doxygen graphviz build-essential zlib1g-dev qt5-default libhdf5-dev libprotobuf-dev libprotoc-dev protobuf-compiler libcurl4-openssl-dev
   

3. If you plan to create the eCAL python language extension (here as an example for the python 3.6 version):

   sudo apt-get install python3.6-dev python3-pip
   python3 -m pip install setuptools
   

Ubuntu 20.04 dependencies

1. Install the dependencies from the ordinary Ubuntu 20.04 repositories:

   sudo apt-get install git cmake doxygen graphviz build-essential zlib1g-dev qt5-default libhdf5-dev libprotobuf-dev libprotoc-dev protobuf-compiler libcurl4-openssl-dev
   

Ubuntu 16/18/20 build

1. Compile eCAL with the following options:

   mkdir _build
   cd _build
   cmake .. -DCMAKE_BUILD_TYPE=Release -DECAL_THIRDPARTY_BUILD_PROTOBUF=OFF -DECAL_THIRDPARTY_BUILD_CURL=OFF -DECAL_THIRDPARTY_BUILD_HDF5=OFF
   make -j4
   

2. Create a debian package and install it:

   cpack -G DEB
   sudo dpkg -i _deploy/eCAL-*
   

3. Optional: Create and install the eCAL python egg (Only available if you enabled the BUILD_PY_BINDING CMake option in step 2):

   cmake --build . --target create_python_egg --config Release
   sudo python3 -m easy_install _deploy/ecal-*
