我的代码:
BlockyWorld.hpp
#ifndef BLOCKYWORLD_H
#define BLOCKYWORLD_H
#include <CImg.h>
namespace logic {
class BlockyWorld {
public:
BlockyWorld( const CImg<float>* heightmap );
};
}
#endif // BLOCKYWORLD_H
BlockyWorld.cpp
#include "BlockyWorld.hpp"
namespace logic {
BlockyWorld::BlockyWorld( const CImg<float>* heightmap ) {}
}
的main.cpp
#include <CImg.h>
#include "logic/BlockyWorld.hpp"
//...
CImg<float> heigthMap;
logic::BlockyWorld world( &heigthMap );
//...
编译时我遇到很多错误:
main.cpp中:
include\logic\blockyworld.hpp(9): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
include\logic\blockyworld.hpp(9): error C2143: syntax error : missing ',' before '<'
main.cpp(85): error C2664: 'logic::BlockyWorld::BlockyWorld(const logic::BlockyWorld &)' : cannot convert argument 1 from 'cimg_library::CImg<float>' to 'const int'
1> No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
BlockyWorld.hpp&amp; CPP
include\logic\blockyworld.hpp(9): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
include\logic\blockyworld.hpp(9): error C2143: syntax error : missing ',' before '<'
include\logic\blockyworld.cpp(4): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
include\logic\blockyworld.cpp(4): error C2143: syntax error : missing ',' before '<'
我不认为这是一个循环包含错误,有时会导致这些错误=)。 我必须定义构造函数错误或者我定义实现错误?现在正在寻找一个小时的答案,所以我现在真的会用一个解释。
只是为了澄清 - 我不是初学的c / c ++程序员,但这些模板令人困惑:(
祝你有个愉快的一天,感谢你的回答。
答案 0 :(得分:1)
CImg
似乎是cimg_library
命名空间的一部分。
将using namespace cimg_library
添加到BlockyWorld.hpp文件的顶部,或更改函数签名以使用命名空间,如下所示:
BlockyWorld( const cimg_library::CImg<float>* heightmap );
与πάνταῥεῖ一起建议匹配指针和引用类型。
