ormat ‘%X’ expects argument of type ‘unsigned int’, but argument 2 has type ‘void*’

Question

在利用caffe训练torcs自动驾驶出了问题

int main(int argc, char** argv) {
::google::InitGoogleLogging(argv[0]);

////////////////////// set up memory sharing
void *shm = NULL;
struct shared_use_st *shared;  
int shmid;

shmid = shmget((key_t)4567, sizeof(struct shared_use_st), 0666|IPC_CREAT);  
if(shmid == -1)  
{  
    fprintf(stderr, "shmget failed\n");  
    exit(EXIT_FAILURE);  
}  

shm = shmat(shmid, 0, 0);  
if(shm == (void*)-1)  
{  
    fprintf(stderr, "shmat failed\n");  
    exit(EXIT_FAILURE);  
}  
printf("\n********** Memory sharing started, attached at %X **********\n", shm); 

报错：

我的解答思路和尝试过的方法 ： 添加linux的头文件 #include <netbd.h>但是没用

求求大神帮帮我 磕头了！！！！

你的opencv版本不对，没有这个方法，文件：tools/torcs_run_2lane.cpp:144:22: error: ‘cvLoadImage’
你需要安装编译 3.4.x 版本的 OpenCV
