Build failure on Humble

[sandeepdutta]

Hello All,

I am trying to build on Humble , and I get this error. Starting >>> isaac_ros_visual_slam --- stderr: isaac_ros_visual_slam
CMake Error at /home/sandeep/Desktop/ros2_humble/install/ament_cmake_core/share/ament_cmake_core/cmake/index/ament_index_get_resource.cmake:62 (message): ament_index_get_resource() called with not existing resource ('cuvslam' 'isaac_ros_nitros') Call Stack (most recent call first): CMakeLists.txt:37 (ament_index_get_resource)

Do I need to install some other packages.

Thank you Sandeep

Take a look at step 2 of quickstart. You have to clone isaac_ros_nitros to bring in cuvslam library.

Thank you so much Swapnesh, I will try this, Is there a way to run this natively i.e. without docker ? Sandeep

Hi, I've had the same issue as @sandeepdutta and after cloning the isaac_ros_nitros as @swapnesh-wani-nvidia suggested, I'm getting another error:

---

  Add the installation prefix of "vpi" to CMAKE_PREFIX_PATH or set "vpi_DIR"

I'm also trying to build it locally without luck (there are some other ROS2 projects on my workstation working properly).

Earlier, I tried to use your docker files as Quickstart suggests, but there are some problems e.g. cherry picking some commit from some fork in a not compatible way, using docker images which are already outdated and not present on docker hub etc. I've spent a day or two to figure it out, but still without luck to make the examples running.

That's why I decided to run it natively w/o docker.

By any chance, @swapnesh-wani-nvidia could you take a look at the docker files in your repo (used in the Quickstart) and validate if they are up-to-date? Maybe your team could fix them quickly - it's definitely something preventing people from getting into Isaac-Ros easily.

Thank you!

Hi @mikolodz , we've recently updated our documentation and consolidated it on our new site here.

Could you please take a second look at our Docker setup instructions and see if it works for you this time? We provide a Docker image specifically because the web of dependencies required for Isaac ROS is very complicated; resolving them manually will be a challenging endeavor.

If you are sure that you want to run natively without Docker, then you should follow along each line of the Dockerfile.x file 'layers' and manually install the appropriate dependencies.
