Clang ++ 4.0.0 Kompilierungsfehler in Windows

Ich benutze clang 4.0.0 kompiliert aus der Quelle auf Windows 10 (32-Bit-OS, x86-Prozessor). Ich versuche, meinen cpp Code zu llvm ir code des Formats ll zu kompilieren. Hier ist ein Beispielcode, die Klirren mit kompilieren fehlschlägt:Clang ++ 4.0.0 Kompilierungsfehler in Windows

#include <windows.h> 
#include <tlhelp32.h> 
#include <fstream> 
#include <mapi.h> 
#include <memory> 
#include<stdio.h> 

/* Function to calculate x raised to the power y */ 
int power(int x, unsigned int y) 
{ 
    if (y == 0) 
     return 1; 
    else if (y%2 == 0) 
     return power(x, y/2)*power(x, y/2); 
    else 
     return x*power(x, y/2)*power(x, y/2); 
} 

/* Program to test function power */ 
int main() 
{ 
    int x = 2; 
    unsigned int y = 3; 

    printf("%d", power(x, y)); 
    return 0; 
}

Dies ist nur ein Beispielcode ist, aber es ist das gleiche Verhalten in allen C++ Code, der die genannten Header-Dateien enthalten. Ich verwende den folgenden Befehl, um llvm ir Code zu kompilieren:

clang++ -S -emit-llvm assiral.cpp -o assiral.ll

Beim Übersetzen bekomme ich folgende Fehlermeldung:

C:\Sample>clang++ -emit-llvm -S assiral.cpp -o assiral.ll

Was ich erwarte, dass Sie den Befehl nach dem Ausführen der Bytecode-Datei erzeugt hat (.ll Datei). Ich habe viele Posts gesehen, wo sie eine Flagge einführen: '-fms-compatibility-version = 19' zusammen mit dem Befehl. Das hinzugefügte Flag wird jedoch als unbekanntes Argument gekennzeichnet. Ich arbeite mit MSVS 2017. Vielleicht verwende ich diese Flagge falsch. Aber ich bin jetzt seit einem Tag in dieser Sackgasse. Jede Hilfe oder Anregung würde sehr geschätzt werden.

Bitte fügen Sie ein kleines kompilierbares Beispiel bei. – OmnipotentEntity

Vielen Dank für das Aktualisieren Ihrer Frage. Mit einer leicht modifizierten Quelle, um Windows spezifische Header zu entfernen, kompiliert es unter Linux gut. Also würde ich mit der Fehlersuche beginnen. Versuchen Sie, Ihre Includes neu anzuordnen und diejenigen zu entfernen, die nicht benötigt werden. – OmnipotentEntity

Was genau meinst du? Aufgrund der Header-Probleme kommt es nicht zu einer Kompilierungsstufe. –

Dies wurde behoben, indem der korrekte Pfad zu den Header-Dateien in der Umgebungsvariablen INCLUDE hinzugefügt wurde. Die meisten meiner Fehler wurden behoben, nachdem ich die Pfade festgelegt hatte. Dies schließt den Fehler ein, bei dem das Kompilieren einer C++ - Datei, die auf bestimmte Kopfzeilen wie windows.h verweist, eine nicht gefundene Datei ergibt.

-Link auf, wie das gleiche zu tun: List all environment variables from command line?

Sie auch ein anderes Problem beheben, das ist:

link fatal error lnk1104 cannot open file 'libcmt.lib'

durch die Umgebungsvariable LIBPATH Einstellung an die richtige Stelle des libcmt.lib-zu-Punkt Datei. Ich fand meine bei:

C:\Program Files\Microsoft Visual Studio 14.0\VC\lib

Diese trivialen Fragen ließ mich verbringen einige Tage, um herauszufinden. Hoffe, das spart jemandem die gleichen Probleme.
