First follow Using xstow for local installations

• Add this line to .bashrc

export YARP_DATA_DIRS=${HOME}/local/share/yarp

• Dependencies:

sudo apt-get install git 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 qml-module-qt-labs-settings

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

cd ~/local/src/yarp/build
make install
cd ~/local/DIR
xstow yarp

• In case you had ROS (ignore if you don't know what ROS is):

xstow swig-wx
xstow opencv2

• In one console run yarpserver3
• Connect a webcam to one of the usb ports of the computer
• In another console run:

yarpdev --verbose --device opencv_grabber

• In another console run: yarpview
• In another console run: yarp connect /grabber /yarpview/img:i

• To test yarp in python:
• Open ipython and then:

import yarp
buffer=yarp.BufferedPortBottle()

• You should not get any errors in the last two commands

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.

cd ~/local/DIR
xstow -D yarp
cd ~/local/src/yarp
git pull
cd build
make -j10
make install
cd ~/local/DIR
xstow yarp
