在VC6.0中是否无法编译通过普通类中的模板成员函数，详见内：

[bigqin]

代码：


1、test.h
#ifndef _TEST_H_
#define _TEST_H_

class A
{

public:
A(){};
~A(){};
static void print(int i);
};


class B
{

public:
B(){};
~B(){};
static void print(int i);
};


class C
{

public:
C(){};
~C(){};
template< class T >
void test(int num)
{
T::print(num);

};
};

template< class T >
void test(int num)
{
T::print(num);

};

#endif


2、test.cpp

#include <stdio.h>
#include "test.h"

void A::print(int i)
{
printf("A::i = %d\n", i);

}

void B::print(int i)
{
printf("B::i = %d\n", i);

}

void main()
{
C p;
p.test<A>(2); //在VC下有编译错误，用g++再linux下可以正常编译
p.test<B>(2); //在VC下有编译错误，用g++再linux下可以正常编译



}


在VC6.0下编译错误：

--------------------Configuration: test - Win32 Debug--------------------

对，应该按楼上的这样设计类。

// test.h
#ifndef _TEST_H_
#define _TEST_H_

class A
{
public:
A(){};
~A(){};
static void print(int i);
};

class B
{
public:
B(){};
~B(){};
static void print(int i);
};

template<class T>
class C
{
public:
C(){};
~C(){};
void test(int num);
};

#endif

// test.cpp
#include <stdio.h>
#include "test.h"

void A::print(int i)
{
printf("A::i = %d\n", i);
}

void B::print(int i)
{
printf("B::i = %d\n", i);
}

template<class T>
void C<T>::test(int num)
{
T t;
t.print(num);
}

void main()
{
C<A> p1;
p1.test(2);

C<B> p2;
p2.test(2);
}

晕，我觉得是vc的bug，我也弄了好几天，都没有搞明白为什么，没有模板类就好了

不是bug ,是VC6不支持模板嵌套
