我有.cpp个文件，必须包含Console.h。在文件中，我正在尝试创建一个地图（稍后用于游戏）。
#include "Console.h"
void DrawMap( void );
void DrawTile( int x, int y );
void DrawMap( void )
{
for( int y = 0; y < MAP_HEIGHT; y++ )
{
for( int x = 0; x < MAP_WIDTH; x++ )
{
DrawTile(x, y);
}
}
}
void DrawTile( int x, int y )
{
console.Position( x, y );
switch( nMapArray[y][x] )
{
case TILE_FLOOR:
console.Color( GREY );
console << '.';
break;
case TILE_WALL:
console.Color( GREY );
console << '#';
break;
}
在Console.h我没有放入地图布局（因为我不完全确定如何做到这一点）。
在VS2012中编译此代码时，我遇到两个错误：
错误LNK2019：未解析的外部符号“public：virtual class IConsole＆amp; __thiscall Win32Console :: Color（unsigned short）”（？Color @ Win32Console @@ UAEAAVIConsole @@ G @ Z）在函数“void __cdecl DrawTile（int）中引用，int）“（？DrawTile @@ YAXHH @ Z）
和
错误LNK1120：1个未解析的外部
