请问下下面这个是什么情况啊

root@lixiaofei-System-Product-Name:/home/lixiaofei/Downloads/dnw/2440_USB/dnw_linux/secbulk# make -C /lib/modules/$(uname -r)/build M=$pwd modules
make: Entering directory `/usr/src/linux-headers-3.5.0-17-generic'
make[1]: *** No rule to make target `/usr/src/linux-headers-3.5.0-17-generic/arch/x86/syscalls/syscall_32.tbl', needed by `arch/x86/syscalls/../include/generated/asm/unistd_32.h'.  Stop.
make: *** [archheaders] Error 2

看起来是编译内核模块需要的文件"syscall_32.tbl"在/usr/src/linux-headers-3.5.0-17-generic/下找不到。也许你需要下载完整的内核源代码。下载的方式取决于你PC上用的Linux发行版。
另外，secbulk方式dnw已经没人维护了，论坛上有人做了改进，参考http://www.aiothome.net/read.php?tid-1502.html
