Hi, >This USB video class function driver implements a video capture device from the >host's point of view. It creates a V4L2 output device on the gadget's side to >transfer data from a userspace application over USB. >The UVC-specific descriptors are passed by the gadget driver to the UVC >function driver, making them completely configurable without any modification >to the function's driver code. I wanted to test this code. I git cloned[1] tree. It has v4l2-event.[c,h] and so I assume that now this tree has support for v4l2 event code. But, while compilation, I am getting this error. [root@viral linux-next]# make uImage > /dev/null && make modules CHK include/linux/version.h CHK include/generated/utsrelease.h make[1]: `include/generated/mach-types.h' is up to date. CALL scripts/checksyscalls.sh Building modules, stage 2. MODPOST 5 modules ERROR: "v4l2_event_dequeue" [drivers/usb/gadget/g_webcam.ko] undefined! ERROR: "v4l2_event_init" [drivers/usb/gadget/g_webcam.ko] undefined! make[1]: *** [__modpost] Error 1 make: *** [modules] Error 2 And by looking at the code, those symbols are not exported and thus the error is obvious. Can you please point me out where to take v4l2-event code? I tried to look for on linuxtv.org but was not able to locate the right code.
