Kann Winsock2.h in MSVC 2010 nicht enthalten

Question

Ich kann WinSock2.h in einem msvC++ 2010-Projekt nicht einschließen. Zuerst habe ich etwas falsch gemacht, also habe ich ein leeres Projekt erstellt, um meine geistige Gesundheit zu testen. Das leere Projekt ist wie folgt

#include <Windows.h> 
#include <WinSock2.h> 


int main(void){ 

    system("echo Hello World"); 
    system("pause"); 
    return 0; 

}; 

Es kompiliert und arbeitet ohne die Linie #include <WinSock2.h> in Ordnung, aber es scheitert mit einer langen Liste von Fehlern, wenn ich versuche zu tun und sind Winsock2.h.

Fehler:

Ich gehe davon aus, dass Microsoft, was los zu verteilen wäre nicht schlecht Header-Dateien in ihrem SDK?

Answer 1

Ich glaube, dass Sie diese Fehler erhalten, weil windows.h winsock.h enthält. Kehren Sie die Reihenfolge Ihrer Includes um, sodass WinSock2.h vor windows.h steht. WinSock2.h hat einige #defines darin, um windows.h davon abzuhalten, winsock.h einzubinden

Answer 2

Ich stellte sicher, dass ein #include "Winsock2.h" vor jedem #include "windows.h" und "#include" Winsock.h“, und dies löste den Fall ab.

nur eine Frage der Geduld, schauen enthält einen nach dem anderen und stellen diese Reihenfolge, zuerst #include‚Winsock2.h‘dann #include‚windows.h‘

Ich überprüfte die rekursiven Includes, ich entdeckte die Header-Dateien, die (rekursiv) einige #include "windows.h" und "#include" Winsock.h "enthalten und ein # include" Winsock2.h "schreiben. In diesen Dateien habe ich # include "Winsock2.h" als erstes hinzugefügt.
