Git

Q: Git returns access timeout when I try to clone the repository

git.launchpad... access timeout

This usually happens when your computer is behind a firewall, try to configure git to use the appropriate proxy server

Camera not working\detected

Q: How do I see which Intel RealSense cameras are connects?

Linux:

Open shell:

$ lsusb | grep 8086

Windows:

1. Click the Win-Key+X keys
2. Choose Device Manager
3. Look under Imaging devices for "Intel RealSense" cameras

Q: I connected the camera to the USB port but it is not recognized

❗️ Make sure your camera is connected using USB 3.0 ❗️

If your camera is connected via USB 3.0, check to make sure your OS detects the camera (how?).

Q: I'm using a virtual machine and the camera is not working

Due to the USB 3.0 translation layer between native hardware and virtual machine, the librealsense team does not support installation in a VM. If you do choose to try it, we recommend using VMware Workstation Player, and not Oracle VirtualBox for proper emulation of the USB3 controller.

Q: Streaming gets stuck on windows

When working on Windows 8.1, make sure you have KB3075872 and KB2919355 installed. These patches are addressing issues with 8.1 video drivers, resolved in Windows 10.

Installation

Q: How do I enable librealsense logs?

To change the log level of LibRealSense logger, you need to set a local variable named LRS_LOG_LEVEL and initialize it with the desirable log level:

Linux:

$ export LRS_LOG_LEVEL="<Log Level>"

Windows:

$ set LRS_LOG_LEVEL="<Log Level>"

• A LibRealSense log will be created even when an application does not activate the LibRealSense logger.

Q: GCC Internal Error

The gcc compiler issues the following error while compiling:

gcc: internal compiler error

This might indicate that you do not have enough memory or swap space on your machine. Try closing memory consuming applications, and if you are running inside a VM increase available RAM to at least 2 GB.

Python

Q: CMake shows an error when I try to build with Python bindings

The following message appears:

Could NOT find PythonInterp (missing: PYTHON_EXECUTABLE)

Please check the following:

• Make sure Python is installed
• On Windows: If you've just installed python, reboot (or log off) and try again
  • Try the answers suggested here: building-opencv-libraries-from-source-files

Python config failure: Python is 32-bit, chosen compiler is 64-bit

If this message appears you should install python 64 bit
