ZED utilities crashes

Software

Hi,

I’m trying to use the ZED SDK on my machine with my ZED 2. Here is my current setup that has been installed successfully:

  • OS: Ubuntu 24.04
  • CUDA version 12.8
  • cuDNN version 9.8
  • TensorRT version 10.9
  • ZED SDK 5.0

The installation of the ZED SDK has been completed without installing the SDK Python API since on Ubuntu 24.04 gives problems (you can’t install pip packages system-wide, it throws errors if you try to do it).

Running ZED Diagnostics everything seems fine.

Here are the errors when I try to run ZEDfu, ZED_Depth_Viewer and the spatial mapping sample.

Hi @Scheggetta
Welcome to the StereoLabs community.

Are you working in headless mode or on a laptop with a discrete GPU?

These two support pages can help you solve your issues:

This seems to be a part of the solution.

Basically, I’m on a clean installation of Ubuntu on my desktop PC with an RTX 4060 Ti.

When executing glxinfo | grep OpenGL i get indeed OpenGL vendor string: Intel (since I’m using an Intel CPU with integrated graphics). If I run __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia ZED_Depth_Viewer, then the neural model is loaded successfully and the GUI as well, and everything works.

If I run __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia ZEDfu, the error remains the same.

Instead, if I install CUDA 12.6 and ZED SDK 4.2.5, ZEDfu manages to start up. And again, with SDK 4.2.5, __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia ZEDfu works and I can even use the neural models

It seems that ZEDfu for SDK 5.0.0 has been built with Qt5 or other shared libraries not compatible with the standard Ubuntu 24 ones (or I messed up the installation of Qt or other libraries, even though I only followed the recommended steps), independently of NVIDIA driver usage (offload) or not. Another proof of that is that ZEDfu 5.0.0 with CUDA 12.6 throws the same errors.

I verified that the Qt5 libs are installed in the system folders. For completeness, I provide the ldd output of ZEDfu 5.0.0:
