我在用c寫程序，標準是C99，編譯器是gcc。用的是windows下的Clion
我有三個文件：main.c SeqList.c define.h
在程序中我會定義結(jié)構(gòu)體并且定義的結(jié)構(gòu)體可能出現(xiàn)在任意一個源文件中，所以我的想法是在define.c中定義，然后供各個源文件使用。下面的代碼是define.c中的全部代碼

#ifndef DATA_STRUCTURE_DEFINE_H
#define DATA_STRUCTURE_DEFINE_H
#define MAX 100
//線性表的順序存儲結(jié)構(gòu)
typedef struct
{
    //指向第一個節(jié)點的指針
    int *firstNode;
    //表當前的長度
    int length;
    //表最大的長度
    int size;
}SeqList, *PSeqList;
#endif //DATA_STRUCTURE_DEFINE_H

我想在SeqList.c中使用define.c，下面是我的SeqList.c的代碼

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

/**
 * 初始化
 * @param p
 * @return
 */
int initial(PSeqList p)
{
    p->length = 0;
    p->size = MAX;
    p->firstNode = (int *)malloc(sizeof(int)*(p->size));
}

/**
 * 創(chuàng)建
 * @param p
 * @return
 */
int create(PSeqList p)
{
    int i, length;
    int *index = p->firstNode;

    if(p->firstNode == NULL){
        printf("Invalid list\n");
        exit(-1);
    }

    printf("Input the length of the node\n");
    scanf("%d", &length);

    for(i = 0; i < length; i++){
        printf("Input the node value\n");
        scanf("%d", index++);
    }
}

下面的是main.c的代碼

#include <stdio.h>
#include "SeqList.c"

int main()
{
    SeqList seqList;

    initial(&seqList);
    create(&seqList);
}

然后我點了Clion中的運行按鈕，如下圖

但是報錯了，如下

不知道是哪里做的不對，求大神指教。PS:我在Linux的虛擬機下執(zhí)行沒有任何問題
