Question

移植从GCC 2.95.3代码海湾合作委员会新的编译时错误4.4.2结果：

too few template-parameter-lists 

下面是一个抽象和该代码的简化示例。该错误发生在标记线上。

#include <iostream> 
using namespace std; 

template<class SomeType> class SomeTemplate 
{ 
    public: 
    SomeType msg; 
    void Func(); 
}; 

void SomeTemplate<long>::Func()  //--- Error Here --- 
{ 
    cout << "SomeType size: " << sizeof (msg) << endl; 
} 

int main() 
{ 
    SomeTemplate<long> MyType; 
    MyType.Func(); 
} 

Answer 1

写

template <> 
void SomeTemplate<long>::Func()   
{ 
    cout << "SomeType size: " << sizeof (msg) << endl; 
}
