错误：STD之间的”重载歧义::复制

我有象下面这样的代码：错误：STD之间的”重载歧义::复制

#include<set> 
#include<iterator> 

std::set<std::string> s1; 
std::set<std::string> s2; 
std::set<std::string> myresult; 

void some_func() { 
    std::set_difference(s1.begin(), s1.end(), s2.begin(), s2.end(),std::inserter(myresult,myresult.begin())); 
}

这给了我编译错误：

/export/SunStudio/SUNWspro/prod/include/CC/Cstd/./algorithm.cc", line 2161: Error: Overloading ambiguity between "std::copy<__rwstd::__rb_tree<std::string, std::string, __rwstd::__ident<std::string, std::string>, std::less<std::string>, std::allocator<std::string>>::const_iterator, std::insert_iterator<std::set<std::string>>>(__rwstd::__rb_tree<std::string, std::string, __rwstd::__ident<std::string, std::string>, std::less<std::string>, std::allocator<std::string>>::const_iterator, __rwstd::__rb_tree<std::string, std::string, __rwstd::__ident<std::string, std::string>, std::less<std::string>, std::allocator<std::string>>::const_iterator, std::insert_iterator<std::set<std::string>>)" and "copy<__rwstd::__rb_tree<std::string, std::string, __rwstd::__ident<std::string, std::string>, std::less<std::string>, std::allocator<std::string>>::const_iterator, std::insert_iterator<std::set<std::string>>>(__rwstd::__rb_tree<std::string, std::string, __rwstd::__ident<std::string, std::string>, std::less<std::string>, std::allocator<std::string>>::const_iterator, __rwstd::__rb_tree<std::string, std::string, __rwstd::__ident<std::string, std::string>, std::less<std::string>, std::allocator<std::string>>::const_iterator, std::insert_iterator<std::set<std::string>>)".

这必须是特定于SunStudio的：我在Mac上用C++编译器编译了代码，并且它没有编译任何警告。 – dasblinkenlight 2011-12-26 11:24:50

经典ADL/Koenig查找问题的这种气味。 – 2011-12-26 11:26:04

你忘了添加

#include<algorithm>

添加到您的代码
