undefined symbol: _ZN2cv3MatC1Ev #2467

arpaterson · 2022-09-03T22:50:21Z

I have done a source build of realsense-ros and librealsense (native backend + CUDA, but SKIPPING the kernel patches) on a nvidia AGX Orin.
It was suggested here that this might work.
I am getting undefined symbol: _ZN2cv3MatC1Ev when trying to launch.

Output of uname -a

I think this might be related.

I noticed I have /usr/local/lib/librealsense.so.2.51.
It seems I used the -b option git checkout -b v2.50.0 and created a local branch "v.2.50.0" pointing at the current HEAD (v2.51).

Cleaning up and using git checkout v2.50.0...

... did not resolve this.

arpaterson · 2022-09-04T01:13:58Z

And neither did building with the RS_USB backend.

the rosdep/apt installed ros-noetic-realsense2-camera and ros-noetic-librealsense2 work, but I need to build with CUDA, and preferably the native backend.

MartyG-RealSense · 2022-09-04T07:17:12Z

Hi @arpaterson If you install librealsense and the RealSense ROS wrapper together from packages with the wrapper's Method 1 instructions then the packages will be based on the RSUSB backend and not contain CUDA support. However, CUDA support accelerates just three types of function: color conversion, depth-color alignment and pointcloud. So unless you are setting align_depth to true or using the pointcloud filter, having CUDA support enabled in librealsense is unlikely to provide a performance benefit.

At #2326 where the error undefined symbol: _ZN2cv3MatC1Ev occurred on a Jetson Xavier NX, a RealSense ROS user at #2326 (comment) suggested a solution that solved the error in that particular case.

arpaterson · 2022-09-05T01:02:20Z

I am currently setting align_depth true, although I am unsure if I will continue to do that. This ROS project uses an AGX orin now, but should also run on a nano.

MartyG-RealSense · 2022-09-05T10:14:09Z

Have you had the opportunity to try the solution at #2326 (comment) which states that it can work with RSUSB = false (native backend).

Whilst CUDA support is not included when installing from packages with the ROS wrapper's Method 1 instructions, it is included if you build librealsense and the ROS wrapper separately (librealsense from Jetson packages or source code, the ROS wrapper from source code). Instructions for installing librealsense from packages on Jetson are at the link below.

https://github.com/IntelRealSense/librealsense/blob/master/doc/installation_jetson.md#4-install-with-debian-packages

CUDA support is automatically included in the librealsense packages. If librealsense is built from source code with CMake then you can add CUDA support by including -DBUILD_WITH_CUDA=true in the CMake build instruction.

arpaterson · 2022-09-05T12:34:15Z

I will try that shortly, however from today until the 18th I will not have the equipment.

I will come back to this on my return

MartyG-RealSense · 2022-09-05T12:47:41Z

Thanks very much @arpaterson for the update. I look forward to your next report. Good luck!

arpaterson · 2022-09-05T13:03:29Z

To clarify:

In the jetson instructions, we are referred to the ubuntu instructions
"Follow the Ubuntu installation guide to install the missing components and configuration items:"

for ubuntu20.04 the ubuntu guide suggests
sudo apt-get install libglfw3-dev libgl1-mesa-dev libglu1-mesa-dev at
I think I missed this step before.

And then returning to the jetson instructions
sudo apt-get install git libssl-dev libusb-1.0-0-dev libudev-dev pkg-config libgtk-3-dev -y

runing the udev script, configure and make

Am I following that correctly?
is it necessary to install libglfw3-dev libgl1-mesa-dev libglu1-mesa-dev at?

MartyG-RealSense · 2022-09-05T13:42:18Z

My interpretation of the instructions would be as follows.

Use the instruction below to install core packages required to install the librealsense binaries:

sudo apt-get install git libssl-dev libusb-1.0-0-dev libudev-dev pkg-config libgtk-3-dev

Use the instruction below to install distribution-specific packages for Ubuntu 20:

sudo apt-get install libglfw3-dev libgl1-mesa-dev libglu1-mesa-dev at

Run the Intel Realsense permissions script from the librealsense root directory:

./scripts/setup_udev_rules.sh

The installation instructions state that libglfw3-dev libgl1-mesa-dev libglu1-mesa-dev are necessary if you want to build the SDK with support for OpenGL-enabled graphical examples, otherwise the core SDK will be configured for a headless environment without a graphics display.

arpaterson · 2022-09-05T16:49:50Z

OK, yes I picked that up after re-reading the instructions.
I proceed with the packages installed for graphical examples.

I added:
find_package( OpenCV REQUIRED)

and modified:

include_directories(
    include
    ${realsense2_INCLUDE_DIR}
    ${catkin_INCLUDE_DIRS}
    ${OpenCV_INCLUDE_DIRS}
    )

target_link_libraries(${PROJECT_NAME}
    ${realsense2_LIBRARY}
    ${catkin_LIBRARIES}
    ${CMAKE_THREAD_LIBS_INIT}
    #{OpenCV_LIBRARIES}
    )

But I still have this error when launching rs_rgbd.

In the realsense2_camera build output everything looks normal except for:

-- Set runtime path of "/home/sacvp-user/catkin_ws/install/lib/librealsense2_camera.so" to ""

It is the right track though, OpenCV is not being linked.

librealsense is built from source (realsense-viewer works)
apt ros-noetic-librealsense and ros-noetic-realsense2* are not installed.
realsense2_camera is in my ros catkin workspace

opencv4.5.0 is built from source
and the existing opencv from jetpack5 has not been replaced/removed.

Perhaps it is something to do with this?

MartyG-RealSense · 2022-09-06T10:38:18Z

The RealSense ROS wrapper does not support an RGBD launch by default and support for it has to be installed first before using the wrapper's rs_rgbd.launch launch file. Can you confirm if you have installed RGBD support, please? It can be done on Noetic using the instruction below.

sudo apt-get install ros-noetic-rgbd-launch

arpaterson · 2022-09-10T18:10:14Z

Yes, I have installed rgbd-launch Anthony Paterson On 6.

It was established earlier in this discussion at #2467 (comment) that librealsense and the RealSense Viewer were working correctly on Jetson Orin. However, the ROS wrapper has the undefined symbol error when launching.

As you suggest in the above link, it may be related to installing OpenCV 4.5.0 from source, since OpenCV installation is not a required step in the ROS wrapper install instructions.

MartyG-RealSense · 2022-09-17T07:15:19Z

Hi @arpaterson Do you require further assistance with this case, please? Thanks!

MartyG-RealSense · 2022-09-23T06:59:08Z

Case closed due to no further comments received.

arpaterson · 2022-10-03T10:00:01Z

Is it possible to reopen this?

MartyG-RealSense · 2022-10-03T10:02:43Z

Yes, it is fine to re-open it if you wish to resume the case.

arpaterson · 2022-10-03T10:46:13Z

Are there any requirements on opencv?
I have built openCV with CUDA, and it appears correctly in python3, jtop shows
OpenCV: compiled CUDA: YES.

The only thing I can see is the openGL support is not there "NO" in openCV build information.

Support for OpenGL graphics in librealsense on Jetson would be enabled by either building librealsense from source code with CMake and including the build term -DBUILD_GRAPHICAL_EXAMPLES=true, or building from packages and installing the 'librealsense-utils' package with the instruction sudo apt-get install librealsense2-utils

A non-RealSense discussion at mdegans/nano_build_opencv#51 provides advice about building OpenCV on Jetson Nano with OpenGL support.

I think I've solved this through a combination of

not making typos in CMakeLists.txt
understanding ros/catkin workspace sourcing better
compiling opencv properly (my script is basically the same as mdegans)

I don't have any clear learnings to share, but the problem is solved.

For the record heres what I did

Compiled opencv with CUDA, but no GTK, QT, or opengl support ( those lead to a different unrelated opencv compilation error, I cannot get opencv later than 4.5.0 to compile with opengl and GUI features on my orin due undefined reference to glXGetProcAddressARB() )
build librealsense with native backend and cuda, without patching the kernel.
included realsense-ros in my projects catkin workspace
modified realsense-ros CMakeLists.txt to find opencv and include it as per here
catkin_make'd it and sourced the workspace properly.

Additionally, I

made sure librealsense was not installed from apt. At one point I had run make, but not sudo make install. Removing the apt version of librealsense just avoided confusion as to which one was running.
made sure ros-noetic-realsense-ros was not installed from apt, for the same reason.

It is possible that between having apt installed versions, workspace sourcing, etc that I was not running the compiled version of librealsense.

Anyay, the changes to realsense-ros CMakeLists.txt works.

Just before closing this,
@MartyG-RealSense Do you have any idea what performance change/how much GPU usage I should see?
I'm not sure how to confirm that the Orin GPU is being utilized for the D455, and not just for desktop rendering.

I see almost none, and low framerates when connected over xrdp, but that is expected.

Connected to a monitor I see a solid 30FPS in rviz, up to 45 if uncapped.

MartyG-RealSense · 2022-10-05T13:23:19Z

That's excellent news that you achieved a solution. Thanks so much for sharing the details with the RealSense ROS community!

Below are some example figures for CPU vs GPU performance when using alignment with and without CUDA. The figures are a few years old but should provide a rough guide for expectations of reduction in CPU usage with CUDA.

At a recent case at IntelRealSense/librealsense#10911 a RealSense ROS user who was checking whether librealsense's CUDA support was enabled reported that if the GPU was being utilized then it would be registered in nvtop.

arpaterson · 2022-10-12T14:59:37Z

I will have a chance to look at nvtop this weekend. If I do not see the expected resource use I will reopen, or open another issue. Thank you again!

MartyG-RealSense · 2022-10-12T15:22:28Z

You are very welcome. I look forward to your next report. Good luck!

MartyG-RealSense · 2022-10-24T06:32:14Z

Hi @arpaterson Do you have an update about this case that you can provide, please? Thanks!

MartyG-RealSense · 2022-11-04T18:08:53Z

Case closed due to no further comments received.
