odom_estimation_node and laser_processing_node dying

[cdiazruiz]

I have installed all dependencies and built the package but when I run it odom_estimation_node and laser_processiong_node die immediately. Could this be that one of the dependencies has not been properly installed?

Using Ubuntu 18 and Ros Melodic

i have same problem. did you solved that?

We also had this issue and found that it's simply version depending. If you use

• Ubuntu 18.04
• ROS melodic
• PCL 1.8 (installed over apt)
• Ceres 1.14
  then you should be good to go. Also be aware that increasing the C++ standard above 11 (which is used by default in floam) you could also run into issues. Hope this solves it also for you guys.

I configured the environment according to the requirements above, except that the ros version is noetic. However, I still had the same problem when I tested the code with VLP-16. Did you know how to solve the problem?

As I wrote, in our specific configuration it worked, so it seems to be a version dependency. If you can downgrade to melodic then you should test this, otherwise you probably need to see which libs you have to upgrade to make it work and coming with this there might be some code changes required.

If you cannot change the ROS version (what was also in our case) you could also put everything into a docker container and do a communication above to be ROS and version independent. It's definitely more effort and slows down the whole system, however it was sufficient for our tests.
