Packet Errors

[Vied71]

I'm learning Socket Programming and I've been Stuck on creating the packets. This isn't even my code it's from the SFML github wiki. My SFML library config is correct because I can make GUIs without error.While Compiling this code I get the errors:
undefined reference to 'sf::IPAddress::IpAddres(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&0'

undefined reference to 'sf::Packet::operator <<(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&0'

undefined reference to 'sf::Packet::operator>>(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&0'

what compiler are you using ?

total guess here, but maybe you have to go to the project settings and check the box for C++11

That Didn't Work. I still get the same errors

Please screen of the errors.

Here are the errors

My guess is that you don't use the exact same compiler as was used for building SFML. The easiest way to fix this is by rebuilding SFML with your compiler.

Ok, I've compiled SFML and put the new lib and dll files in my SFML directory. Now the program builds successfully. But, when I run the program I get this error.
The procedure entry point
_ZN2sf6PacketIsERKNST7_cxx1112basic_stringIcSt11char_traitsIcESalcEEE could not be located in the dynamic link library.

It's still using the old DLL somewhere.
