Can you change the run.launch file into using the GDB debugging and then attach the log here? <!--node pkg="fast_lio_sam_qn" type="fast_lio_sam_qn_node" name="fast_lio_sam_qn_node" output="screen"/-->
<node pkg="fast_lio_sam_qn" type="fast_lio_sam_qn_node" name="fast_lio_sam_qn_node" output="screen" launch-prefix="gdb -ex run --args"/> I guess you have plural FLANN libraries on your computer. |

Thread 10 "fast_lio_sam_qn" received signal SIGABRT, Aborted. Program terminated with signal SIGABRT, Aborted. GDB debug log is this? |

You should type "bt" and enter after you get the error in GDB debug. |
|
(gdb) bt Is GDB like this？ |
|
--Type for more, q to quit, c to continue without paging-- |

The problem is probably from your data. Could you check your data again? |
Hello, I encountered the same issue as you. Initially, I didn't have this problem when I used it, but recently, after recompiling, the issue appeared. Have you managed to solve it? |

[New Thread 0x7fff53ff7700 (LWP 1431930)] Hello, this always appears before each segmentation fault. Do you have any good solutions? |

I just cloned this repository on the clean computer and tested the algorithm with KITTI and HILTI datasets without any errors or issues. It works well. I am using Ubuntu 20.04 with ROS-noetic, ROS-noetic-desktop-full's default PCL. Only one thing came up in my mind is the version of TEASER++. If you want to test it, git clone https://github.com/MIT-SPARK/TEASER-plusplus.git
cd TEASER-plusplus
git reset --hard baf69d948d77e8fe496a82e2fa3b1f41a9b1156f
mkdir build && cd build
cmake .. -DENABLE_DIAGNOSTIC_PRINT=OFF
sudo make install -j16
sudo ldconfigThen, re-build this repository again. |
|
Okay, I will test it today. Thank you for your patient response. |

I recently replaced a brand new computer, which solved this problem. I don't know the reason either. thank you ！！！ |
