编译两个C文件不起作用，找不到标头

我尝试从终端编译两个c文件时遇到问题。我拥有的文件是：main.c user_info.c。它们都在同一个文件夹中。尝试编译时，我使用：gcc main.c user_info.c -o program它给出如下错误消息：main.c：3：10：致命错误：找不到'user_info.h'文件

main.c

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

int main() {

struct user person1;
struct user person2;

person1.userId = 1;
person2.userId = 2;

puts("Enter the first name of user 1");
gets(person1.firstName);
puts("Enter the first name of user 2");
gets(person2.firstName);

printf("User 1 id is %d\n", person1.userId);
printf("User 2 first name is %s\n", person2.firstName);

return 0;
}

user_info.c

struct user {
int userId;
char firstName[25];
char lastName[25];
int age;
float weight;
};
