template hilfe

[xErY]

ich habe

#ifndef __PHP_EXT__TWOPLAYER
#define __PHP_EXT__TWOPLAYER


#ifdef __GNUC__
#if (__GNUC__ >= 3)
#include <ext/hash_map>
#else
#include <hash_map>
#endif
#endif

#include <stddef.h>
class CTwoPlayer {
public:
	CTwoPlayer(int _p1, int _p2) {
		p1 = _p1;
		p2 = _p2;
	}


	operator size_t() const { return (size_t)(p1 | (p2<<16));};

	bool operator < (const CTwoPlayer &r) const {
		if (p1 < r.p1) return true;
		else if (p1 == r.p1 && p2 < r.p2) return true;
		return false;
	}

	int getP1() const { return p1;}
	int getP2() const { return p2;}

private:
	int p1, p2;
};



//Hash code computation. Note how it's easy and pleasant to do portable code....

#ifdef __GNUC__
#if (__GNUC__ >= 3)
namespace __gnu_cxx {
	struct hash<CTwoPlayer>
	{
		size_t operator()(const ::CTwoPlayer &truc) const { return (size_t)(truc); }
	};
};
#else 
namespace std {
	__STL_TEMPLATE_NULL struct hash<CTwoPlayer>
	{
		size_t operator()(const ::CTwoPlayer &truc) const { return (size_t)(truc); }
	};
}
#endif // __GNUC__ >= 3

#endif // __GNUC__

#endif // __PHP_EXT__TWOPLAYER

und er sagt mir

In file included from Teams.h:4,
from repasm.cpp:14:
CTwoPlayer.h:46: Fehler: an explicit specialization must be preceded by 'template <>'
make: *** [repasm.o] Error 1

ich verstehe das nicht mag mir wer helfen bitte

Hallo ich weiß zwar nicht was du machen möchtest aber sollte eine
Definition eines Templates nicht so ausschauen:

...
namespace __gnu_cxx {
        template <typename T> struct hash
        {
                size_t operator()(const T &truc) const { return (size_t)(truc); }
        };
};
...

Instanziieren:

__gnu_cxx::hash<CTwoPlayer> object;
