回答1:

Thanks to @SilencePhil, I found a relevant StackOverflow answer. This question is not the same question, but has the same solution, namely to replace std=c++11 with std=gnu++11 in the call to g++.



回答2:

In Clion

  • go to CMakeList.txt, this document is next to main.cpp and
  • change -std=c++11 with -std=gnu++11


回答3:

The accepted answer is hardly a solution. Having to set the C++ standard version should not be required.

I strongly suggest you try the MinGW-w64 GCC, which does not have this problem (or at least I haven't seen it reported or experienced it myself).



回答4:

I still have not found a solution. The above did not work for me. For now, I'm using visual studios compile via command line cl /EHsc somefile.cpp. Here is a reference, https://msdn.microsoft.com/en-us/library/ms235639.aspx.



回答5:

If you are working inside CODE::BLOCKS go to Settings->Compiler. Select 'compiler settings with GNU GCC compiler' under Selected Compiler. Check the option "Have g++ follow the C++14 ISO C++ language standard [-std=c++14]" in General menu.
