这是编译器错误

kdtilemapper.cpp:14: error: 'tiles' was not declared in this scope
kdtilemapper.cpp:17: error: 'const class KDTileMapper' has no member named 'tiles'

，这里是有问题的代码。

KDTileMapper::KDTileMapper(const KDTileMapper & rhs):TileMapper(rhs,tiles)
{
source = rhs.source;
tiles = rhs.tiles;
}

这是班级

class KDTileMapper : public TileMapper
{
public:
    KDTileMapper( const SourceImage & si,const vector<TileImage> & tiles);
    ~KDTileMapper();
    KDTileMapper(const KDTileMapper & rhs & tiles);
    KDTileMapper const & operator=(KDTileMapper const & rhs);
    int map_tiles(MosaicCanvas & mosaicOut) const;
private:
    KDTree<TileImage>* tileMapKDT;

原文

Here's the compiler error

kdtilemapper.cpp:14: error: 'tiles' was not declared in this scope
kdtilemapper.cpp:17: error: 'const class KDTileMapper' has no member named 'tiles'

here is the code in question.

KDTileMapper::KDTileMapper(const KDTileMapper & rhs):TileMapper(rhs,tiles)
{
source = rhs.source;
tiles = rhs.tiles;
}

here is the class

class KDTileMapper : public TileMapper
{
public:
    KDTileMapper( const SourceImage & si,const vector<TileImage> & tiles);
    ~KDTileMapper();
    KDTileMapper(const KDTileMapper & rhs & tiles);
    KDTileMapper const & operator=(KDTileMapper const & rhs);
    int map_tiles(MosaicCanvas & mosaicOut) const;
private:
    KDTree<TileImage>* tileMapKDT;

KDTileMapper::KDTileMapper(const KDTileMapper & rhs):TileMapper(rhs,tiles)

您将参数 rhs,tiles 传递给基类 TileMapper 构造函数。但编译器不知道标识符 tiles 是什么。

也许您的意思是 -

KDTileMapper::KDTileMapper(const KDTileMapper & rhs):TileMapper(rhs,rhs.tiles) 
                                                                 // ^^^ newly added.

但如果您只是让 TileMapper 构造函数通过引用仅接收一个 KDTileMapper 类型的 const 参数，则根本不需要进行修改，因为 tiles 已经是 rhs 对象的一部分（如果它实际上是成员变量。但第二条错误消息表明它不是）。

KDTileMapper::KDTileMapper(const KDTileMapper & rhs):TileMapper(rhs,tiles)

You are passing the arguments rhs, tiles to the base class TileMapper constructor. But the compiler doesn't know what the identifier tiles is.

Probably you meant -

KDTileMapper::KDTileMapper(const KDTileMapper & rhs):TileMapper(rhs,rhs.tiles) 
                                                                 // ^^^ newly added.

But the modification is not at all required if you just make the TileMapper constructor receive just one const argument of type KDTileMapper by reference because tiles is already part of the rhs object ( if it is actually a member variable. But the second error message says it isn't ).
