Segmentation faults in C++ code when compiled/run on ROS Noetic

[alikureishy]

Steps to reproduce:

> Pull this repository into a catkin workspace in a Noetic installation
> Compile with catkin_make
> Run any of the launch files:
    > roslaunch leap_motion vizualization.launch

You will see errors (seg faults) for all the C++ nodes being started, such as "leap_motion_driver_node".

[Note: I understand that the leap motion SDK was only built for python 2.7, but that is not what this above Issue is about. I also understand that Noetic is not presently supported for this driver...but if the issue above is a simple fix, perhaps it could help uses who just want to use the C++ portions of the driver].

I am also having this issue running the latest ROS Noetic

I tried to throw both the camera node and the driver node into GDB to find where the SEGFAULT was occuring and both brought me to boost::detail::find_tss_data(void const*) in LeapSDK/lib/x64/libLeap.so.

The complete output of the GDB log is below

Hello!

I am unsure when I am able to look into and fix this issue as I don't have easy access to the hardware anymore. However, thanks for reporting this issue regardless.

Hi, just wondering if someone got a fix to run this project on Noetic?

@Safdark @dvigne

The error for this is:

Thanks!

[dvigne]

Hi @rglbiv, no I'm sorry I never picked it back up to try and fix, do you have any additional log lines besides what was output to the ROS console above?

[dingthe4th]

Unfortunately, I think that was all that was outputted, the log messages were not helpful (see below).
I think this is because Noetic is still not supported with this project. I tried with another machine (Melodic) and it works, but I am just trying my luck here to check if someone figured out a solution to make it work with Noetic. Nevertheless, thanks for reaching out!

Hi, just wondering if someone got a fix to run this project on Noetic?

@rglbiv If you need to access leapmotion frame data urgently, a workaround that I used was leapmotion's websocket interface. It's not ideal, but at least can get you the data you need.

[joelsantosvalle]

Hi, just wondering if someone figured how to run this project in Noetic?

@alikureishy @dvigne @rglbiv

[dingthe4th]

@Jasv06 Hello, unfortunately, I used this project for Melodic as I also couldn't figure out on how to run it on Noetic on my own. But I can assure you it works on Melodic version!

[dvigne]

@Jasv06 I never got the time to debug it further so I never got it to run on Melodic. Sorry I couldn't be more help.

[mszuyx]

@Jasv06 I am also hoping to use the driver on Noetic. As @rglbiv mentioned, there isn't much to go on with the error message. But since it works with Melodic, I guess it has something to do with python 2.7 vs 3.4+ (I guess the cpp nodes will run just the same). I wonder if someone has done a python 3 migration for all the scripts to test out this theory.
