我尝试使用emplace()
功能的unordered_map和编译器说,没有这样的功能存在。C++ 11功能与MinGW
我把-std=c+11
和它说cc1plus.exe: error: unrecognized command line option '-std=c+11'
我可以以某种方式使用C++ 11的功能与MinGW的?

C++0x was the working name of a new ISO C++ standard, which was then released in 2011 as C++11 and introduces a host of new features into the standard C++ language and library. This project seeks to implement new C++11 features in GCC and to make it one of the first compilers to bring C++11 to C++ programmers.
C++11 features are available as part of the "mainline" GCC compiler in the trunk of GCC's Subversion repository and in GCC 4.3 and later. To enable C++0x support, add the command-line parameter -std=c++0x to your g++ command line. Or, to enable GNU extensions in addition to C++0x extensions, add -std=gnu++0x to your g++ command line. GCC 4.7 and later support -std=c++11 and -std=gnu++11 as well.
所以,对于GCC 4.3 4.6通过使用-std =的C++ 0x,供以后使用版本-std = C++ 11。库支持map::emplace
被添加到gcc 4.8
相同的错误:“类的std :: unordered_map <性病:: basic_string的
构件我来相信我不能C++ 11,或至少所有的,使用具有4.6 。 – 2013-04-22 13:47:54
你需要gcc 4.8才能使用'map :: emplace',参见[这个问题](http://stackoverflow.com/questions/14075128/mapemplace-with-a-custom-value-type) – TemplateRex 2013-04-22 14:45:23
尝试'C++ 11'而不是'c + 11' – 2013-04-21 20:58:34
要么,要么尝试'C++ 0x' – 2013-04-21 21:05:48
既不能工作(我已经有C++ 0x ON ) – 2013-04-21 21:23:56
