patch-realsense-ubuntu-xenial.sh failure

[JBai1]

Hi,

I am working on getting my newly arrived SR300 work on Ubuntu 16.04 with kernel 4.8.0-58-generic.

When I was trying to build the patched file ./scripts/patch-realsense-ubuntu-xenial.sh following the Linux installation instructions, the following error occurred:

patching file drivers/media/usb/uvc/uvc_driver.c

Hunk # 1 succeeded at 188 with fuzz 2 (offset 20 lines).

I have been looking around for this and it seems that this is a common issue for many new kernels. One response in another post suggests watching https://github.com/IntelRealSense/librealsense/issues/444 Uvcvideo patching issue · Issue # 444 · IntelRealSense/librealsense · GitHub, and it seems that the kernel 4.8 support has already been updated? I would highly appreciate for any hints to this problem.

With regards,

Jerry

I got some useful leads on your issue by googling for this search term:

patching file include/uapi/linux/videodev2.h Hunk # 1 FAILED at 624.

since this is the point where the installation process apparently goes wrong.

A number of people have experienced this HUNK # 1 issue related to videodev2.h. There were not many helpful answers to be found though. The most potentially useful ones I found were:

https://github.com/IntelRealSense/librealsense/issues/119 ubuntu-mainline Hunk # 1 FAILED · Issue # 119 · IntelRealSense/librealsense · GitHub (the very last comment at the bottom of the page looks particularly interesting)

https://github.com/IntelRealSense/librealsense/issues/266 SR300 driver installation issue, distorted/flickering depth image and no infrared image · Issue # 266 · IntelRealSense/li…

Thanks Marty! I have also found these two threads but still cannot solve it. I will keep trying.
