Problem with vpRealSense2 Class Reference #927

Closed lucamarchionna closed 3 years ago

lucamarchionna commented 3 years ago

Hi everyone, I was trying to implement an eye-in-hand configuration through a markerless generic model-based tracking. For doing this, I am going to leverage a RealSense d435i and benefit from the vpRealSense2 Class. However, when I include the header

#include <visp3/sensor/vpRealSense2.h>

an error appear in the catkin_make, mentioning the following:

undefined reference to vpRealSense2::vpRealSense2() undefined reference to vpRealSense2::open(rs2::config const&)

I have successfully installed the 3rd parties according to VISP tutorial. Have you an idea on how to fix this error? Thank you in advance.

Investigate the following points:

is ViSP build with librealsense support ? Check vpConfig.h file to see if VISP_HAVE_REALSENSE2 is defined
it is also possible that you have multiple ViSP installation, some with, some without librealsense support
```
$ sudo updatedb
$ locate libvisp_core.so
```

@lucamarchionna Any update ?

lucamarchionna commented 3 years ago

Thanks for your support. I solved the problem following what you have suggested in another issue. For other users, the steps are:

Identify local installations with sudo updated locate libvisp_core.so
Remove duplicates

Install Synaptic sudo apt-get install synaptic

Run Synaptic sudo synaptic

Delete any installation from packages that contains visp-ros, vision-visp

Build visp in a separate catkin_ws (e.g. visp-ws) following https://visp-doc.inria.fr/doxygen/visp-daily/tutorial-install-ubuntu.html
Clone visp_ros package into your catkin and build it
Use visp dependencies to create your own code
