数组类型有不完整的元素类型错误

Question

我正在尝试编译一个程序，并且相当缺乏经验（边走边自学）。我正在努力解决的一件事是：

overland.h:62:37: 错误：数组类型的元素类型“struct sect_color_type”不完整

extern const struct sect_color_type sect_show[];

const struct sect_color_type sect_show[] = {
/*   Sector Type        Color   Symbol Description  Passable?   Move  R  G  B   */

任何帮助将不胜感激。

编辑：我在 overland.h 中找到了定义

struct sect_color_type
{
sh_int sector;  /* Terrain sector */
char * color;   /* Color to display as */
char * symbol;  /* Symbol you see for the sector */
char * desc;    /* Description of sector type */
bool canpass;   /* Impassable terrain */
int move;             /* Movement loss */
sh_int graph1;  /* Color numbers for graphic conversion */
sh_int graph2;
sh_int graph3;
};

C 中的结构不像 Python 或其他语言中的字典。结构是专门定义的具有命名和大小字段的分组内存块。您将结构视为 collection，但它们不是。

在初始化数组之前，您需要在某处定义一个结构，如下所示：

typedef struct
{
    int sectorType;
    char* Color;
    char Symbol; // you seem to only need a single character for this field according to your example.
    char* Description;
    int Passable;
    int Move;
    int rgb[3];

} sect_color_type;

注意：我将 rgb 移到了它自己的结构内的整数数组中。
