====== Installing YARP in debian ======

==== Install dependencies ====
First follow [[using_xstow_for_local_installations|Using xstow for local installations]]

  * Add this line to .bashrc

<code bash>
  export YARP_DATA_DIRS=${HOME}/local/share/yarp
</code>

  sudo apt install git libgraphviz-dev libace-dev libreadline6-dev libgtkmm-2.4-dev swig libopencv-highgui3.2 libopencv-core3.2 libopencv-dev cmake-curses-gui python-dev qt5-default qtmultimedia5-dev qtdeclarative5-dev qml-module-qtquick-dialogs qml-module-qt-labs-settings qml-module-qtmultimedia libopenmpi-dev qml-module-qt-labs-folderlistmodel libqcustomplot-dev
</code>

==== Compilation and Installation ====

<code bash yarp_installer.sh>
cd ~/local/src/
git clone git://github.com/robotology/yarp.git
cd yarp
mkdir build
cd build
cmake -D CMAKE_INSTALL_PREFIX=${HOME}/local/DIR/yarp -D YARP_COMPILE_BINDINGS=ON -D CREATE_PYTHON=ON -D YARP_USE_PYTHON_VERSION=$(echo $(python --version) | tr -d a-zA-Z[:blank:]) -D CREATE_YARPDATADUMPER=OFF -D CREATE_GUIS=ON -D ENABLE_yarpmod_opencv_grabber=ON YARP_COMPILE_yarpviz=ON ..
make -j10
make install
cd ~/local/DIR
xstow yarp
</code>

==== Test the installation ====

  * In one console run 
<code bash>
yarpserver
</code>
  * Connect a webcam to one of the usb ports of the computer
  * In another console run: 
<code bash>
  yarpdev --verbose --device opencv_grabber
</code>
  * In another console run:
<code bash>
  yarpview
</code>
  * In another console run:
<code bash> 
yarp connect /grabber /yarpview/img:i
</code>
  * To test yarp in python:

  python -c "import yarp; buffer=yarp.BufferedPortBottle();"

  * You should not get any errors with any command

==== Update YARP ====

We try to use the latest yarp version. So some programs may present issues if you stay with old versions. Here are the instructions to updar with the same cmake options. 

<code bash yarp_updater.sh>
  cd ~/local/DIR
  xstow -D yarp
  cd ~/local/src/yarp
  git pull
  cd build
  make -j10
  make install
  cd ~/local/DIR
  xstow yarp
</code>
