Make issue in "make -C /usr/src/linux-headers-`uname -r` M=`pwd` modules"

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.

Could you link to the git tree you are using and paste in the git commit hash? Sometimes I need to tweak the patch for a specific kernel version. Did you compile the whole kernel or download it from a package repo? I may be able to come up with better instructions on how to build. My knowledge of kernel patch development has improved a bit since I wrote that.

Hi @teknotus This is where I got the patch from: https://github.com/teknotus/depthview/tree/kernelpatchfmt

Latest commit is on March 3rd, 2015. As for the hash I get the following for this branch:

ecd476c

Appreciate your help as I am currently not getting IR stream from my camera

[teknotus]

I meant where did you get the kernel source. lts-vivid is a different kernel tree than the Linus Torvalds tree I linked to.

[Nikvand]

@teknotus apt-get source linux-image-$(uname -r)
gets me lts-vivid. uname-r returns: 3.19.0-30-generic

[Nikvand]

@teknotus, gives me the same error when I patch the kernel source I got from Linus Trovald's tree.

[Nikvand]

Here is an update from patching Linus Trovald's tree:

nima@Nimani:~/linux$ (cd drivers/media/usb/uvc/ && make -C /usr/src/linux-headers-uname -r M=pwd modules)
make: Entering directory /usr/src/linux-headers-3.19.0-30-generic' CC [M] /home/nima/linux/drivers/media/usb/uvc/uvc_driver.o In file included from /home/nima/linux/drivers/media/usb/uvc/uvc_driver.c:28:0: /home/nima/linux/drivers/media/usb/uvc/uvcvideo.h:18:34: fatal error: media/videobuf2-v4l2.h: No such file or directory #include <media/videobuf2-v4l2.h> ^ compilation terminated. make[1]: *** [/home/nima/linux/drivers/media/usb/uvc/uvc_driver.o] Error 1 make: *** [_module_/home/nima/linux/drivers/media/usb/uvc] Error 2 make: Leaving directory/usr/src/linux-headers-3.19.0-30-generic'

[Nikvand]

This time it is complaining about "media/videobuf2-v4l2.h"

[teknotus]

I'm thinking the patch is probably OK, but I need to fix my instructions.

[Nikvand]

Appreciate any ideas!

[teknotus]

For the out of kernel tree module I'm working on at the moment the makefile looks like this. KDIR ?= /lib/modules/`uname -r`/build default: $(MAKE) -C $(KDIR) M=$$PWD So rather than the -C going to a headers directory it seems it should be going to a build directory.

[teknotus]

Also librealsense has a patch that supports most of the F200 formats, and a script to patch the kernel. You could try that. https://github.com/IntelRealSense/librealsense/tree/master/scripts
