我正在尝试使用
使用
我该如何解决这个模糊性错误?
boost::assign
来模拟C++11初始化包含std::set
的std::map
。#include <set>
#include <map>
#include <stdint.h>
#include <boost/assign/list_of.hpp>
typedef std::map< uint32_t, std::set< uint32_t> > the_map_t;
the_map_t data = boost::assign::map_list_of( 1, boost::assign::list_of(10)(20)(30) )
( 2, boost::assign::list_of(12)(22)(32) )
( 3, boost::assign::list_of(13)(23)(33) )
( 4, boost::assign::list_of(14)(24)(34) );
使用
boost::assign::list_of
初始化std::set
时,如果单独使用,效果如预期。但是,在尝试上述代码时,在调用std::set
的构造函数时出现歧义:map-assign.cpp:16: instantiated from here
include/c++/4.4.6/bits/stl_pair.h:101: error: call of overloaded set(const boost::assign_detail::generic_list<int>&) is ambiguous
include/c++/4.4.6/bits/stl_set.h:188: note: candidates are:
std::set<_Key, _Compare, _Alloc>::set(
const std::set<_Key, _Compare, _Alloc>&)
[with _Key = unsigned int, _Compare = std::less<unsigned int>, _Alloc = std::allocator<unsigned int>]
include/c++/4.4.6/bits/stl_set.h:145: note:
std::set<_Key, _Compare, _Alloc>::set(
const _Compare&, const _Alloc&)
[with _Key = unsigned int, _Compare = std::less<unsigned int>, _Alloc = std::allocator<unsigned int>]
我该如何解决这个模糊性错误?
list_of(10U)(20U)(30U)
有帮助吗? - aschepler
