求大家看看哪里出了错，我检查了一遍还上网搜了都没成功

主要是你的代码错得看不懂你的意图，没法改。
另外，你这是C代码，还是C++代码？

#include <stdio.h>
#include <stdlib.h>

typedef struct Node
{
    int data;
    struct Node* pNode;
} NODE, * PNODE;

PNODE create_list( void )
{
    int len;
    int i;
    int val;

    PNODE pHead = (PNODE)malloc(sizeof(NODE));
    if (NULL == pHead)
    {
        printf("分配失败，程序终止!\n");
        exit(-1);
    }

    PNODE  pTail = pHead;
    pTail->pNode = NULL;

    printf("请输入您需要生成的链表的节点个数：len = ");
    scanf("%d", &len);

    for( i=0; i<len; ++i )
    {
        printf("请输入第%d个节点的值: ", i+1);
        scanf("%d", &val);
        PNODE pNew = (PNODE)malloc(sizeof(NODE));
        if (NULL == pNew)
        {
            printf("分配失败，程序终止!\n");
            exit(-1);
        }

        pNew->data = val;
        pTail->pNode = pNew;
        pNew->pNode = NULL;
        pTail = pNew;
    }

    return pHead;
}

int main( void )
{
}

是c++应该，代码目的是建一个链表，报错的地方在函数建立那里
