Procedure entry point not found

[Tem8]

Followed this tutorial: https://www.sfml-dev.org/tutorials/2.5/start-cb.php
Trying to run an example program and get error: "Точка входа в процедуру _ZNSt15basic_streambuflcSt11char_traitslcEE7seekposESt4fposliESt13_Ios_Openmode не найдена в библиотеке DLL C:\Users\Администратор\Documents\Codeblocks\SFMLGame\sfml-system-d-2.dll".
I use dynamic link library.
Compiler: mingw-w64 gcc 7.3.0 SEH
SFML ver. - SFML 2.5.1
Link libraries:
sfml-graphics-d, sfml-audio-d, sfml-network-d, sfml-window-d, sfml-system-d for Debug
and sfml-graphics, sfml-audio, sfml-network, sfml-window, sfml-system for Release.

I have moved all dlls from SFML\bin and libstdc++-6 to SFMLGame folder.

From where did you get the libstdc++ library?

Make sure you copy it from the specific compiler bin directory and also copy the gcc libraray.
