I have been writing some simple code that reads files, prints, writes to files and downloads files (via a external executable) To read the files im using mINI which can be found here.
What I'm importing:
string
iostream
cctype
vector
stdio.h
memory
cstdio
stdexcept
sstream
"mini/ini.h"
memory
What I'm defining:
CURL_STATICLIB
I am using this command to compile my code to Windows x32-bit:
i686-w64-mingw32-g++ -o main.exe main.cpp
After compiling and running it on my Windows Machine I get this error:

Der Prozedureinsprungpunkt "_ZNKSt7__cxx1112basic_stringlcSt11char_traitslcESalcEE12find_last_ofEcj" wurde in der DLL "J:\main.exe" nicht gefunden.
Translated with Google Translate:
The procedure entry point "_ZNKSt7__cxx1112basic_stringlcSt11char_traitslcESalcEE12find_last_ofEcj" was not found in the DLL "J:\main.exe".
Any help would be apprieciated!
