//
//实例
template<typename T1, typename T2>
T1 findValue (T1 beg, T1 vend, T2 ival) {
return beg;
}
//声明
template<typename T1, typename T2> T1 findValue (T1 beg, T1 vend, T2 ival);
//运行
findValue (vec.begin(), vec.end(), 5);
编译错误:
undefined reference to `__gnu_cxx::__normal_iterator<int*, std::vector<int, std::allocator<int> > > findValue<__gnu_cxx::__normal_iterator<int*, std::vector<int, std::allocator<int> > >, int>(__gnu_cxx::__normal_iterator<int*, std::vector<int, std::allocator<int> > >, __gnu_cxx::__normal_iterator<int*, std::vector<int, std::allocator<int> > >, int)'|
简化一下就是
undefined reference to `T findValue<T, int>(T, T, int)'|
给我找一下什么情况.. 找不出来
