I have a very simple program:

// hello.cpp
#include <iostream>

using namespace std;

int main() {
   cout << "Hello, world!" << endl;
   return 0;
}

When I used Command Prompt (Windows) and type:

g++ -o hello hello.cpp

I got this error:

In file included from /usr/include/wchar.h:6:0,
                 from /usr/lib/gcc/x86_64-pc-cygwin/4.9.2/include/c++/cwchar:44,

 #include <stddef.h>
                    ^ compilation terminated.

Can anyone solve this problem? I try gcc and everything works fine. It seems that g++ is having some problems. My g++ version is 4.9.2

  • I think this problem indicates a version mismatch between gcc and g++. Can you verify that they are both the same version? – rici Aug 31 '15 at 17:03
  • Your cygwin installation looks broken –  Aug 31 '15 at 17:03
  • my gcc version is 4.9.3. Do they have to be in the same version ? – pexea12 Aug 31 '15 at 17:04

  • Thank you, I will try to reinstall g++ and gcc again. – pexea12 Aug 31 '15 at 17:07

I hope you are working on Linux.

Try installing build-essentials like 

sudo apt-get install build-essential

Even if it did not work then you may have to install libc6-dev.
