Hello, I am trying to set up ROS on my Nao robot. I keep getting the error: "Please make sure that Aldebaran's NaoQI API is in your PYTHONPATH." I found the answer below:

http://answers.ros.org/question/28814/adding-naoqi-to-the-pythonpath

and executed

PYTHONPATH=/my/path/to/naoqi-sdk-1.12-linux32/lib:${PYTHONPATH} ,

with "/my/path/to" being the path to the SDK in my system, but the error did not go away. I am using naoqi-sdk-1.12-linux32, so is the path different for this newer version?

Put this

export AL_DIR=/home/naokinect/nao1.12/naoqi-sdk-1.12-linux32
export LD_LIBRARY_PATH=$AL_DIR/lib
export PYTHONPATH=$AL_DIR/lib:$PYTHONPATH

into your bashrc. Path to the lib may differ to your path. Works for me.

Using NaoQI 1.12.3 this seems to be fixed and the Python API only needs to be in the PYTHONPATH, no more need for LD_LIBRARY_PATH

As SLAMnect wrote, it seems like the NaoQI Python API in version 1.12 also seems to require LD_LIBRARY_PATH set in addition to the PYTHONPATH. But I would suggest against putting the complete directory always in your LD_LIBRARY_PATH in .bashrc. There are many other libraries in this directory and it will mess up your system with conflicting versions of boost for example.

Instead, put

export AL_DIR=$HOME/path/to/naoqi-sdk-1.12-linux32 
export PYTHONPATH=$AL_DIR/lib:$PYTHONPATH

in your .bashrc and either start nao_driver with

LD_LIBRARY_PATH=$AL_DIR/lib roslaunch nao_driver nao_driver.launch

or run

export LD_LIBRARY_PATH=$AL_DIR/lib

only in the terminal where you run nao_driver.
