colcon build --symlink-install failed, missing vpi config file (inside docker)

[SyedShayaan]

Hi there, I faced an error in step 6 of the isaac_ros_nvlox quickstart example. I am running on a jetson orin nano with jetpack 6.0.

This error was inside the docker container. I launched the container using:

cd ${ISAAC_ROS_WS}/src/isaac_ros_common && \
  ./scripts/run_dev.sh

error msg

CMake Error at CMakeLists.txt:31 (find_package):
  By not providing "Findvpi.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "vpi", but
  CMake did not find one.

  Could not find a package configuration file provided by "vpi" with any of
  the following names:

    vpiConfig.cmake
    vpi-config.cmake

  Add the installation prefix of "vpi" to CMAKE_PREFIX_PATH or set "vpi_DIR"
  to a directory containing one of the above files.  If "vpi" provides a
  separate development package or SDK, be sure it has been installed.

what I have tried

sudo apt install libnvvpi2
sudo apt install vpi2-dev

(both were already installed inside the container)

my hunch

Forum says isaac ros is not supported in jetpack 6.0 (link)
However, the jetpack 6.0 release docs says otherwise (link),

Hi @SyedShayaan - yes, you are right that at the time of writing, the most recent Isaac ROS 2.1 release is not compatible with the JetPack 6.0 Developer Preview. For now, please flash JetPack 5.1.2 on your Jetson to continue using the Isaac ROS 2.1 release.

We'll follow up with the JetPack documentation team to clear up any confusion.
