Question

我通过观看这些https://www.youtube.com/watch?v=Bi61lMwhksw&list=PLZ1QII7yudbc-Ky058TEaOstZHVbT-2hg&index=7的youtube讲座来制作国际象棋引擎，但是我得到了未定义的错误，如输出图像所示。我和他一样。

ChessEngine.c主文件

SingleOrder

defs.h，这是我的文件，其中包含所有定义

#include "stdio.h"
#include "defs.h"

extern int Sq120ToSq64[BRD_SQ_NUM];
extern int Sq64ToSq120[64];

int main()
{
    AllInit();
    int index = 0;

    for(index = 0; index < BRD_SQ_NUM; ++index)
    {
        if(index%10==0) printf("\n");
        printf("%5d", Sq120ToSq64[index]);
    }

    printf("\n");
    printf("\n");
    for(index=0; index < 64; ++index)
    {
        if(index%8==0) printf("\n");
        printf("%5d",Sq64ToSq120[index]);
    }


    return 0;
}

请帮助我解决在制作Chess Engine时出现的这些“未定义的引用”错误
