Extension compatibility with Isaac Sim 5.0.0

[lesurJ]

Hello,

Thank you for the nice extension.
I am trying to integrate this extension in the new Isaac Sim 5.0.0 Developer Preview but without success.
I am following this tutorial, but the extension cannot be installed. See error message below

Is there a planned release date for porting this extension to the newest Isaac Sim version?
Thanks

The last release of the extension is now installable and is correctly detected by Isaac Sim. However, following the official tutorial is highlighting some troubles in using and ZED_Depth_Viewer.

I am working on a local workstation with Isaac Sim installed from source and i want to stream locally.

After having created the camera and the Action Graph, the following error arises:

ZED_Depth_Viewer:

Segmentation Fault occurs. Exporting LC_ALL="C" as explained in the warning does not solve this issue.

However, the ZED_Explorer is working fine and I can see the video stream

also when Isaac Sim loads the Zed Extension, this error appears

No idea about the warning. But, I think the first error can be resolved by creating a bin folder in the sl.camera.bridge folder and copying and pasting the libsl_zed file from the ZED SDK installation inside this bin folder. You can find all the ZED SDK files in the Program Files (x86) folder. There you can find the ZED SDK folder and inside there will be this file.
