2 years ago currently, I have no idea what could be wrong here. usual suspects are Eigen + gtsam, but these usually result in errors with some part of the Eigen libary. Here the problem is with some shared pointer. I just compiled and run the code on Ubuntu 20.04 with gcc 9.3.0. Apart from some issues with boost, it worked just fine.
Therefore, I have currently no idea where the problem could be.
hi, thanks for your code!!!
I meet the same question as some issues, and I use 'gdb ./visualizer' and input 'bt' and 'r' , it shows these:
