CMake (Colcon) can not find nvToolsExt about isaac_ros_nvblox HOT 6 CLOSED

Could you please double-check the following:

• Does the path /usr/local/cuda-11.4/targets/aarch64-linux/include/nvToolsExt.h exist on your host?
  ls /usr/local/cuda-11.4/targets/aarch64-linux/include/nvToolsExt.h
• If that path exists on the host, does the same path exist inside the container?
• If both paths exist, try clearing the build/, log/, install/ folders in the ROS workspace and build again?

Thank you for the quick reply! I have verified that /usr/local/cuda-11.4/targets/aarch64-linux/include/nvToolsExt.h exists on both the host and the container. Unfortunately, deleting the build log and install directories and rebuilding does not fix the error.

I did some further debugging over the weekend to isolate, whether or not the issue stems from the Docker setup or something else. On the host, cuda-nvtx-11-4 seems to be installed correctly according to apt-cache, however, CMake fails to find nvToolsExt even outside of the Docker container. CMake finds other components, such as cudart for example, without any issue.

Just to be sure, does the corresponding .so file also exist? /usr/local/cuda-11.4/targets/aarch64-linux/lib/nvToolsExt.so

Could you try uninstalling and reinstalling cuda-nvtx-11-4 via apt?

I can confirm that the .so file did exist as well. Interestingly, I could not get the extensions to be detected and only a complete reflash of the Jetson's OS allowed me to solve the issue. The install procedure and utilised Jetpack version are the same as the previous install; only now nvtx is found without any problem.

Since I managed to get everything working, I will close the issue. Thank you again for your help and best regards.

This also happen when you building a package that already build in some other workspace so if you already build a package in some other workspace just source it and build the remaining packages.

I am also running into this same issue, however it is only affecting the rviz2 plugin
