这是make命令给出的错误

sudo make
make -C /lib/modules/3.2.0-4-rpi/build M= modules
make[1]: Entering directory `/usr/src/linux-headers-3.2.0-4-rpi'

给你一个最简单的方法，在你所用的内核源代码目录下，修改 uvc/Makefile 为：
uvcvideo-objs := uvc_driver.o uvc_queue.o uvc_v4l2.o uvc_video.o uvc_ctrl.o \ 
                  uvc_status.o uvc_isight.o uvc_debugfs.o
uvcvideo-objs  += uvc_entity.o
obj-m := uvcvideo.o

all:
        make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules

clean:
        make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

然后编译：
~/vcs/git/linux/drivers/media/video/uvc$ make
make -C /lib/modules/3.4.0-2-amd64/build M=~/vcs/git/linux/drivers/media/video/uvc modules

即可得到驱动程序文件 uvcvideo.ko 。

我按照 它的 说明git clone下来以后执行里面的build脚本，
它似乎并没有给我编译uvc模块，这是怎么回事？

我在3.2 内核下面编译了驱动从http://www.linuxtv.org 下的，怎么还是没 有 编 译 出uvcvideo.ko这个文件呢 

我应该从哪下这个驱动来编译，或者改什么设置？


从 git log 看，驱动在 3.2 之前已经内置了，无需下载。
