Hi,

when compiling the udev branch i get the following:
fatal error: linux/compiler.h: No such file or directory

so i added " -I ~/linux-3.13.0/include/ " in the makefile. (this is the kernel source i needed for the kernel patch) which got me this:

fatal error: asm/linkage.h: No such file or directory
when i add " -I ~/linux-3.13.0/arch/x86/include/ " which is where the file in the sources
or " -I /usr/src/linux-headers-3.13.0-57/arch/x86/include/ " i get tons of errors.

i had the same problem a few weeks ago but i cant remember how i did it.

any suggestions?

Just to clarify, do I need your kernel patch for uvcvideo to actually use depthview? Right now, when I plug the camera in, I get both video devices, however, uvcvideo explicitly complains in the kernel log about "Unknown video formats" and doesn't list them when queried with v4l2-ctl --list-formats --device=/dev/video2. I'm on Ubuntu 14.04 with kernel 3.16. Is there a quirk or similar trick to let uvcvideo pass all formats to userspace, even unknown ones?

Sincere,
I'm trying to run your repo on Ubuntu 20.04.1 LTS with little luck.

Could you aid me on how to run your basic app?

Thank you greatly.

BTW, this is awesome work and I'd like to donate to help you develop depth-color registration, too. Is it possible to donate using bitcoin?

I just wanted to apply your patch to my Ubuntu 14.04.
It doesn't want to compile, because the include videodev2.h was still not patched.
To make it compile with your manual, I needed to hit the following copy command as well, after patching:

sudo cp include/uapi/linux/videodev2.h /usr/src/linux-headers-`uname -r`/include/uapi/linux/videodev2.h

Is your manual for another version, or should it generally be done my way?

Hi there,

I'm looking at https://launchpad.net/~teknotus/+archive/ubuntu/rs-kernel-ppa/+build/7338621. I am having trouble compiling without the libc files, but the built files seem to be missing from this list. I was successful at installing all the other files, but if I want to install linux-libc-dev for 3.16.0-37.49+realsense:

E: Version '3.16.0-37.49+realsense' for 'linux-libc-dev' was not found

I also tried patching the kernel from Torvald's git repository, unfortunately there were lots of compile time errors, so I gave up on that.

Without this I get the error linux/compiler.h no such file or directory from videodev2.h. I am assuming that this is because I am missing linux-libc-dev. How do I proceed? Thanks.

It should be noted that at the Intel Developer Forum 2015, RealSense announced experimental support for F200 and R200, OSX + Linux that will be available on a "soon" timescale: https://software.intel.com/en-us/articles/what-if-experimental-software

Every UVCIOC_CTRL_QUERY ioctl results in a errno 2: No such file or directory on my system,

I'm running in a Ubuntu 14.04 with a 3.13.0-45 kernel. The application is running fine, I can see the camera feed, just the controls do not work for me.

I was wondering how to convert the 16uint raw output values to distance values (in meters)?

Hello, I am currently using realsense SR300 in Ubuntu 14.04.
(model name : Intel(R) Core(TM) i5-4460 CPU @ 3.20GHz) -using USB 3.0

After connecting the SR300 camera to the computer, computer cannot detect the USB from SR300.
Error saying that "cannot detect video4linux". In my understanding, this might be the power problem. So we tried with powered hub USB that has 4 Port USB 3.0 Hub with 5V/2.5A power adapter, it did not work neither.

-Can anyone know the exact power draw of realsense SR300?
-If someone already have used the powered hub for SR300 or F200, please let me know the information about the that product. Thank you !

Hi ,

I am using SR300, odroid xu4, ubuntu 14.04. After patching I can not see some Index compare to your output, for example I could not see "FlickerIR 8-bit (RELI) ", What would be the problem?

Hi, I get the following error after applying patch and trying to make:

It seems like a header (videodev2.h) is missing. Any ideas are much appreciated.

Hi @teknotus

I had problems applying the patch to any kernel in Ubuntu 14.04 LTS. Perhaps you can see the mistake I'm making and can point me in the right direction:

1. Patch fails to automatically apply with git apply -- the patch failed to apply to 3.13, 3.16, and 4.0 kernel sources, both from Ubuntu sources as well as vanilla kernels from github.com/torvalds. The patch isn't that large so I was able to apply all the diffs by hand.

2. When I went to compile as it was looking at headers in /usr/source/uname-r versus the headers in the downloaded source where modified videodev2.h and uvc_camera.h reside. This results in compile errors because all the new macros in videodev2.h are not found.

Now based on the step:

sudo cp include/uapi/linux/videodev2.h /usr/include/linux/videodev2.h

I'm guessing that that step was intended so that the code would build against /usr/include/linux/videodev2.h. So I tried taking the modified videodev2.h and copying it to /usr/source/uname-r/include/linux/videodev2.h as well. Once I did this I was able to compile the module

3. Once I installed the module, then I attempt to load it and I got tons of missing symbol errors. Here's the output of dmesg:

Looks like a lot of v4l2 calls weren't linked into the module. If you have any insights into what I"m doing wrong, please let me know. Thanks!

Hi teknotus,
I try to use VLC application to read raw data from realsense, and I also use the patch to add UVC format. However, the depth image is green and resolution is not the same with RGB image.
Could you please teach me how to solve them ?

Thanks
Regards

Just for the record, I have a PCAP file which (probably) contains a firmware update of the F200. For those interested, it's available here: http://floe.butterbrot.org/external/firmware_pcap/realsense.pcap
