由于Linux内核版本的问题，在2.6.36以上安装aodv-uu-0.9.6会出现以下问题：

查找DECLARE_MUTEX:
在include/linux/semaphore.h 中
将#define DECLARE_MUTEX(name) 改成了 #define DEFINE_SEMAPHORE(name)
#if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,36)
DECLARE_MUTEX(led_sem);
#else
DEFINE_SEMAPHORE(led_sem);
#endif
因此将kaodv-netlink.c中
static DECLARE_MUTEX(kaodvnl_sem);
修改为：static DEFINE_SEMAPHORE(kaodvnl_sem);
make clean
make
即可
