I am facing this issue even after trying what was mentioned in #252 and #289

This is what I've done so far. 1) cd catkin_ws/src && git clone --recursive git@github.com:leggedrobotics/darknet_ros.git 2) cd .. 3) catkin build darknet_ros -DCMAKE_BUILD_TYPE=Release

Some other extra information: 1) When run nvidia-smi

2) Using Ubuntu 18.04 LTS, ROS Melodic with GPU NVIDIA Quadro P1000

3) When I run ls -l /usr/local/cuda-11.3/lib64/libcuda.so I already have: lrwxrwxrwx 1 root root 46 Jul 12 15:10 libcuda.so -> /usr/lib/x86_64-linux-gnu/libcuda.so.465.19.01 So doesn't this mean that I have already have a symbolic link to the cuda lib?

The error output is:

Had that same issue while building a catkin env during the build of Docker image (but not when building the project from within the image), using nvidia-container-runtime. If that's your case too, I solved it by adding the library stubs among the directories linked in the darknet_ros CMake like so:

link_directories(
    ${CUDA_TOOLKIT_ROOT_DIR}/lib64
    ${CUDA_TOOLKIT_ROOT_DIR}/lib64/stubs
  )

(line is around 145)

This works!!
