Dear Sir.
Thank you for your great projects for DLMS c++ library. I want to read the data of the wattmeter operated by dlms protocol. So I built the development to make the "libgurux_dlms_cpp.a"
During compiling steps, I revised the original source in some places like these.
1) Ignoring the IP6 setup
2) switching the function "fopen_s /fopen", "sscanf_s / sscanf" because of not-finding function error
3) adding "#define ERROR_INVALID_FUNCTION 1, #define ERROR_IO_PENDING 976" in communication.h
I tried to make the build the "GuruxDLMSClientExample.cpp" but the compile error was shown as belows.
My pc condition is "Windows 10, MinGW(32 bit)". Pleas help me and thank you for your kindness.

Hi,
Hi,
You are using MinGW and it doesn't support Windows sockets. Check how to use sockets in MinGW and replace those functions (socket, closesocket, etc.).
BR,
Mikko
