链表读入商品信息，编译发生错误

Question

想要将商品信息读入链表中，但编译发生错误，求解；
代码如下：

```#include<stdio.h>
#include<stdlib.h>
#define GOODS_FILE_NAME "goodsinfo.txt"
#define MAX_ID_LEN 30
#define MAX_NAME_LEN 30
#define MAX_PRICE_LEN 30
#define MAX_DISCOUNT_LEN 30

extern int CurrentCnt;

typedef struct {
char goods_id[MAX_ID_LEN];
char goods_name[MAX_NAME_LEN];
int goods_price;
char goods_discount[MAX_DISCOUNT_LEN];
int goods_amount;
int goods_remain;
} GoodsInfo;


typedef struct node
{
GoodsInfo data;
struct node *next;
} GoodsList;

int main ()
{
    GoodsList **L;
    GoodsInfo info;
    GoodsList *head_list=(GoodsList*)malloc(sizeof(GoodsList)),*p;
    *L=head_list;
    FILE *fp=fopen("goodsinfo.txt","r");
    if(fp==NULL){
        printf("error: file not found");
        return 0;
    }
    else {
        while(!feof(fp)) {
            fscanf(fp,"%s%s%d%s%d%d",info.goods_id,info.goods_name,&(info.goods_price),info.goods_discount,&(info.goods_amount),&(info.goods_remain));
            p=(GoodsList *)malloc(sizeof(GoodsList));
            head_list->next=p;
            head_list->data=info;
            CurrentCnt++;
        }
    }
    fclose(fp);
    p->next=NULL;
    printf("商品的链表文件已建立，有%d个商品记录\n", CurrentCnt);
}
    
编译错误如下：

供参考：

#include<stdio.h>
#include<stdlib.h>
#define GOODS_FILE_NAME "goodsinfo.txt"
#define MAX_ID_LEN 30
#define MAX_NAME_LEN 30
#define MAX_PRICE_LEN 30
#define MAX_DISCOUNT_LEN 30
extern int CurrentCnt;
typedef struct {
    char goods_id[MAX_ID_LEN];
    char goods_name[MAX_NAME_LEN];
    int  goods_price;
    char goods_discount[MAX_DISCOUNT_LEN];
    int  goods_amount;
    int  goods_remain;
} GoodsInfo;

typedef struct node
{
    GoodsInfo data;
    struct node* next;
} GoodsList;
int main()
{
    GoodsList* L = (GoodsList*)malloc(sizeof(GoodsList));
    L->next = NULL;
    GoodsInfo info;
    GoodsList* head_list = L, * p;
    FILE* fp = fopen("goodsinfo.txt", "r");
    if (fp == NULL) {
        printf("error: file not found");
        return 0;
    }
    else {
        while (!feof(fp)) {
            fscanf(fp, "%s%s%d%s%d%d", info.goods_id, info.goods_name, &info.goods_price, info.goods_discount, &info.goods_amount, &info.goods_remain);
            p = (GoodsList*)malloc(sizeof(GoodsList));
            p->data = info;
            p->next = NULL;
            head_list->next = p;
            head_list = p;
            CurrentCnt++;
        }
    }
    fclose(fp);
    //p->next = NULL;
    printf("商品的链表文件已建立，有%d个商品记录\n", CurrentCnt);
