执行用 C++ 编写的 .exe 的问题（使用 mingw 编译器）

Question

I am new to programming and trying to learn C++ using C++ Primer (5th ed.). I have written this code that is directly from the book. The issue is when trying to execute the .exe results with this prompt popping up

The procedure entry point _ZNKSt9basic_ioslcSt11char_traitslcEEcvbEv could not be located in the dll

The .cpp

#include <iostream>

main ()
{
    int sum = 0, val = 0;

    while (std::cin >> val) 
        sum += val;

    std::cout << "The sum is: " << sum << std::endl;

    return 0;
}

Take a look at the directory where your mingw compiler is installed. Within the "bin" directory you should finde several "*.dll" files like "libwinpthread-1.dll", "ligstdc++-6.dll" and so on...

These libraries are required to execute your application since mingw needs some platform wrapping magic (its a port of gcc for linux).

Try to copy these dll's into the same folder of where your "*.exe" is located.

If this does not help: The error message is a bit confusing since I would expect it to report a dll file is missing instead of a missing procedure. In this case it looks like your compiler installation is broken or as already mentioned your build environment is not correctly set up. Which mingw version are you using, where did you get it from?
