Hello!
I had this problem when building a package on ROS2 Humble.
I have all the libs and it seems that even the signatures of the erroneous functions are in the libcudla.so libs, etc.
But I still can’t build the ROS package. What could be the problem?
I use nvcr.io/nvidia/l4t-jetpack:r36.4.0 with the command
nvidia-docker run -it --rm --mount type=bind,source=$(pwd),target=/workspace --gpus all --runtime nvidia nvcr.io/nvidia/l4t-jetpack:r36.4.0
Then
colcon build --packages-select modern_detect --symlink-install --continue-on-error --cmake-args -DBUILD_TESTING=OFF -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DCMAKE_BUILD_TYPE=Release
Starting >>> modern_detect
--- stderr: modern_detect
