Failed to load plugin libgazebo_naoqi_control.so

[andres5450]

Hi!

I've followed every step in the readme file, but when i execute roslaunch gazebo_naoqi_control nao_gazebo.launch i get the following error:

**Error [Plugin.hh:149]** Failed to load plugin libgazebo_naoqi_control.so: libgazebo_naoqi_control.so: cannot open shared object file: No such file or directory i'm using ros indigo

Greetings!

Hey!

Did you catkin_make successfully? Because if the build of the package failed, there will be no libgazebo_naoqi_control.so and thus will not work.

[andres5450]

/ home / user / catkin_ws / src / I have -gazebo_naoqi_control -nao_gazebo -nao_meshes_master

catkin_make in the folder catkin_ws, the following error: it's okay? Or the folders go in another direction?

[costashatz]

it's okay? Or the folders go in another direction?

The packages are in the right place, but you need the NAOqi simulator SDK; it requires that you have bought a NAO (and have access to Aldebaran's software). It seems that you do not have it. If you do have it, then you need to set your environmental (or CMAKE) variables correctly: see here.

Can you give the output of ls /home/diego/naosoftware/simulator-sdk-1.12.0.59-linux32?

[andres5450]

Can you give the output of ls /home/diego/naosoftware/simulator-sdk-1.12.0.59-linux32?

I can not find another sdk simulator :/

[costashatz]

Can you give me the output of ls /home/diego/naosoftware/simulator-sdk-1.12.0.59-linux32/include?

I think you either have an older (or newer) version of NAOqi simulator SDK (or partially installed one?). I will try to check tomorrow what version I was using and come back to you. In the mean time, can you try replacing this line by:

find_path(NAOqiSIM_INCLUDE_DIR alnaosim/alnaosim.h HINTS ${NAOqi_INCLUDE_HINTS} )

And see what happens...

download the NAOqi simulator SDK http://cui.unige.ch/~agulleir/tools/NAO/Version%201.14.5/

replacing the line in FindNAOqiSIM.cmake: I think the error is due to the origin of that SDK simulator, I did not find another ;/

[costashatz]

I think you just need to download the 64bit version.

[andres5450]

I think you just need to download the 64bit version.

repeat the error ... remote connection?, maybe I'm doing something wrong

[costashatz]

repeat the error ... remote connection?, maybe I'm doing something wrong

I downloaded the file I linked and it has many more files in the include directory. So you are doing something wrong when downloading or extracting the file. These files should be enough for this library to work..

[andres5450]

i think the problem is with NAOqiSIM_FOUND_COMPONENTS, it says that couldn't found NAOqiSIM becaouse of that. How can i hard code that path? And what is that trying to find? 'cause i have every folder that you mention in the past comments so, i've just hardcoded my naosim path and it keeps throwing me that error.

PS: i have every .h file in order to the paths

[costashatz]

i think the problem is with NAOqiSIM_FOUND_COMPONENTS

I do not think so.

PS: i have every .h file in order to the paths

Do an ls to the folder of include in the simulator SDK to see what the files/folders are..

[andres5450]

there is the screenshot of the 64bit version, there are many more files than in the 32 bits version. What can it be?

If you have time can i meet you on discord or something?

Thanks a lot for your help!

[costashatz]

Can you send me the error message?

CMakeLists.txt # Tell Program where to find NAOqi/NAOqiSIM bin add_definitions(-DNAOQI_SDK="/home/diego/naosoftware/pynaoqi-python2.7-2.1.4.13-linux32") add_definitions(-DNAOQI_SIM_SDK="/home/diego/naosoftware/simulator-sdk-1.14.5-linux64/include")

FindNAOqiSIM.cmake find_path(NAOqiSIM_INCLUDE_DIR alcommon/alproxy.h HINTS ${NAOqi_INCLUDE_HINTS} )

i don't have any idea of what else i can do, i did all the possible changes i could do, that the proyects allow me but nothing works.

[costashatz]

Tell Program where to find NAOqi/NAOqiSIM bin add_definitions(-DNAOQI_SDK="/home/diego/naosoftware/pynaoqi-python2.7-2.1.4.13-linux32") add_definitions(-DNAOQI_SIM_SDK="/home/diego/naosoftware/simulator-sdk-1.14.5-linux64/include")

Restore these to the originals (in the CMake file).

Open a terminal and do the following:

cd ~/catkin_ws
export AL_SIM_DIR=/home/diego/naosoftware/simulator-sdk-1.14.5-linux64/
export AL_DIR=/home/diego/naosoftware/pynaoqi-python2.7-2.1.4.13-linux32/
rm -rf build
rm -rf devel
catkin_make

It could be convenient to add these lines at the end of your ~/.bashrc file (so that you don't have to re-type them everytime):

export AL_SIM_DIR=/home/diego/naosoftware/simulator-sdk-1.14.5-linux64/
export AL_DIR=/home/diego/naosoftware/pynaoqi-python2.7-2.1.4.13-linux32/

[andres5450]

i did what you told me, and it didn't work, but now show a different error.

restore the original(CMakeLists.txt) # Tell Program where to find NAOqi/NAOqiSIM bin add_definitions(-DNAOQI_SDK="$ENV{AL_DIR}") add_definitions(-DNAOQI_SIM_SDK="$ENV{AL_SIM_DIR}")

at the end of the file .bashrc this is what appears

source /opt/ros/indigo/setup.bash export PYTHONPATH=${PYTHONPATH}:/home/diego/naosoftware/pynaoqi-python2.7-2.1.4.13-linux32 export LD_LIBRARY_PATH="/home/diego/naosoftware/naoqi-sdk-2.1.4.13-linux32:$LD_LIBRARY_PATH" export AL_SIM_DIR=/home/diego/naosoftware/simulator-sdk-1.14.5-linux64/ export AL_DIR=/home/diego/naosoftware/pynaoqi-python2.7-2.1.4.13-linux32/

i open the terminal and enter the commands:

thanks for all help, i really appreciate it!

You need boost installed: sudo apt-get install libboost-dev-all.

[andres5450]

i already have installed:

[costashatz]

Can you do ls in the alnaosim folder?

Also what is your cpu, os etc?

[andres5450]

ls in the alnaosim folder:

[andres5450]

i follow this tutorial https://stackoverflow.com/questions/5389853/doesnt-compile-if-included-boost-thread-in-linux-ubuntu10-10

now this is the new error message:

effective this file alnaosim_camera_definitions.h is not found in alnaosim:

[costashatz]

I have a feeling that this nao sdk is either incomplete or corrupt (i.e., files missing etc.). A few months ago I tried the code with the official sdk and there was no issue.

[andres5450]

where i found the official sdk?, i donwloaded choregraphe and c++ naoqi sdk this official page https://community.ald.softbankrobotics.com/en/resources/software/language/en-gb/robot/nao-2?sort_by=weight&sort_order=ASC, but i didn't found sdk simulator :c

[andres5450]

i downloaded simulator-sdk-2.1.2.17-linux32 this official page https://community.ald.softbankrobotics.com/en/resources/software/former-nao-versions-simulators

• compile catkin_make successful!!!!:

• roslaunch gazebo_naoqi_control nao_gazebo.launch error:

[costashatz]

Great news! Please refer to the ROS documentation for these issues: http://wiki.ros.org/roslaunch

Most probably you haven't sourced the correct bashrc file or something..

[andres5450]

i've executed the source /devel/setup.bash command show up to command at tabular roslaunch gazebo_naoqi_control nao_gazebo.launch.

• executed `roslaunch gazebo_naoqi_control nao_gazebo.launch

• NAO figure doesn't show, but in the gazebo view option when i click joints, center of mass, contacts it show the next thing. The only problem is that NAO doesn't visualize.
