किसी भी मदद

Answer 1

'दौर' और 'roundf' त्रुटियों की जगह (लाइनों 103 और 110) ठीक करने के लिए:

साथ

static double round(double num) 
static float roundf(float num) 

:

static inline double round(double num) 
static inline float roundf(float num) 

ठीक करने के लिए 'signbit' त्रुटि मैक्रो पालन करते हुए उसे लगा (लाइन 128):

#if _MSC_VER < 1800 
inline bool signbit(double num) { return _copysign(1.0, num) < 0; } 
#endif 

Answer 2

आपके द्वारा चलाए गए के लिए धन्यवाद "vcvars32 संकलन से पहले .bat "? ऐसा लगता है कि वीसी ++ के पर्यावरण चर उचित रूप से सेट नहीं हैं।

वीसी ++ के पर्यावरण के बारे में जानकारी के लिए http://msdn.microsoft.com/en-us/library/f2ccy3wt.aspx देखें।

अलविदा

Answer 3

आपकी समस्या यह है कि आप Visual Studio 2012 लेकिन 2013 वी.एस. 2012 का उपयोग नहीं करते है, जबकि वी.एस. 2013 VS12 है और VS11 है अपने पथ "C: \ प्रोग्राम फ़ाइलें (x86) \ माइक्रोसॉफ्ट विजुअल स्टूडियो 12.0" वीएस 2013 से संबंधित है।

मूल समस्या हालांकि यह है कि वीएस 2013 सी 99 अनुपालन है जो वी 8 इंजन और जावास्क्रिप्ट में समस्याएं पैदा करता है।

वर्तमान में कोई समाधान नहीं है लेकिन मैन्युअल पैचिंग है।

Answer 4

वी.एस. 2013 संगतता के लिए आधिकारिक patch का प्रयोग करें।

Answer 5

ऊपर प्रस्तावित दो पैच पर्याप्त नहीं थे।

समाधान Git क्यूटी 4 रिपोजिटरी से 3 फ़ाइल को पकड़ने की थी:: मेरे मामले में, उन्हें क्यूटी 4.8.5 के लिए आवेदन करने के बाद मैं एक त्रुटि मिली

Answer 6

@ AppDealer के awnser काम करता है, अगर आपको MathExtras.h फ़ाइल के दोनों उदाहरणों पर इसे लागू करना है। (JavaScriptCore में एक और Webkit में एक और है कि आप एक HashSet निर्माण समस्या में पड़ जाएगा।

No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called .\wtf/HashSet.h 

इन दोनों मुद्दों patchthis issue पर पाया जा सकता है के साथ फिक्स कर रहे हैं।
