2 months ago Hi @monson-li It looks as though you are building building librealsense 2.55.1 from source code with CMake. Which installation method did you use, please?
For example, you can download the source code for 2.55.1 as a zip file and build it using the instructions at https://github.com/IntelRealSense/librealsense/issues/9931#issuecomment-964289692
Do you experience the same problem with building librealsense 2.55.1 from source code if you do so using the libuvc backend build script at the link below, please?
