Ich habe das Problem bereits gelöst. Ich habe einfach nur vergessen die windows.h zu includen.
Ich bin neu in diesem Forum. Ich wollte mit Hilfe des IoWarriors und C++ eine kleine Automatisierung bauen. Dazu muss ich unter anderem die Temperatur messen. Leider gibt mir mein C++-Compiler lauter Fehlermeldungen in Verbindung mit der iowkit.h. Ich benutze Dev-C++ mit mingw32 um alles zu kompilieren. Anbei erstmal der Sourcecode des Testprogramms (ist leider noch recht unsauber, soll ja nur zum Testen sein):
#include <iostream>
#include "iowkit.h"
using namespace std;

Über schnelle und kompetente Hilfe würde ich mich sehr freuen.
Danke im Voraus.
