GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported

Describe the bug
I am facing the bug using opencv-4.1.0 with darknet_ros. I understand that they are using different version on gtk+. Is there a workaround on this issue?

Hello, any progress? I met the same error. Though I compiled opencv and darknet_ros with -D WITH_GTK_2_X=ON, it doesn't work.

Check your opencv versions, in my case i had opencv4.4 and 4.2 installed in same time, uninstalled 4.4 and it works.
Hope it helps !

Hi, I have same error. How you check your opencv versions. Can you explain your solution with steps please ? :)

In my case, i changed the enable_opencv= true to false in darknet_ros/config/ros.yaml file and the error is gone, hope it helps.

for Opencv version use interminal :
python3

import cv2
print(cv2.version)
4.2.0

If you put openCv=false i think i will be too slow , try this installation in this link if still need help.

Thanks for your reply. I am working on the Orin Nano and I got this error. I worked on my PC and Jetson Nano I didn't get an error and everything is working. I don't understand why I got this error in Orin Nano.

I will work on your solution, and after that, I will share the output.
