symbol lookup error: libORB_SLAM2.so, undefined symbol: _ZN5DBoW24FORB1LE

[HayatoTajiri]

I can't run orb_slam2.

environment(環境)
Jetson nano
Ubuntu 18.04LTS
ROS melodic
opencv ver.3.3.1

I had used orb_slam2 on jetson nano with Ros melodic. However I haven't been able to use Orb_slam2 before installing Realsense r200 drivers(librealsense,realsense_camera,etc). Probably.

error content(エラー内容)

I can't understand what causes. please tell me solutions,anyone. thanks.

[FaikVural]

I have same problem, Please help us

[HayatoTajiri]

Hi. Finally, I could't solve it but, I formated SDcard and reinstalled ubuntu, so it is running.

[SkylerGao]

I also have the same problem, maybe the version problem of DBOW ? Waiting for the solution from "Big God (Chinese words)"...

[SkylerGao]

forgot to say... I met the problem in ORB-SLAM3

I encountered the same issue with ORB_SLAM2. What solved the issue for me was moving ORB_SLAM2 to a different directory whch had not been built by catkin build. In my case, I had tried to add new packages to the workspace and build them with catkin_build. Undoing that solved the problem for me.

Hi this is caused by repetitive installation of DBoW2 in my case. I searched for the DBoW2 in my computer and removed all files named DBoW2 under /usr/local and the problem was solved

[Viky397]

Hi, I've tried that @wh200720041 and the error still persists for me. Any other recommendations? Thanks!

Make sure all previous DBoW is removed, including DBoW folder and its related files under /usr/.

1、 ldd -r libORB_SLAM3.so find: libDBoW2.so => xxxxx/xxxxx/xxxxx/lib/libDBoW2.so remove this libDBoW2.so and make again, can solved this problem

================================== 2、/ORB_SLAM2/Thirdparty/DBoW2/CMakeLists.txt or /ORB_SLAM3/Thirdparty/DBoW2/CMakeLists.txt
from： add_library(DBoW2 SHARED ${SRCS_DBOW2} ${SRCS_DUTILS}) target_link_libraries(DBoW2 ${OpenCV_LIBS}) to： add_library(DBoW2_1 SHARED ${SRCS_DBOW2} ${SRCS_DUTILS}) target_link_libraries(DBoW2_1 ${OpenCV_LIBS})

then：open /ORB_SLAM2/CMakeLists.txt from： ${PROJECT_SOURCE_DIR}/Thirdparty/DBoW2/lib/libDBoW2.so to： ${PROJECT_SOURCE_DIR}/Thirdparty/DBoW2/lib/libDBoW2_1.so
