dzięki za pomoc

Answer 1

Aby rozwiązać 'okrągłe' i błędy 'roundf' replace (linie 103 i 110):

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

z:

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

Aby rozwiązać 'signbit' błąd ująć ją następujące makro (linia 128):

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

Answer 2

masz run „vcvars32 .bat "przed kompilacją? Wygląda na to, że zmienne środowiskowe VC++ nie są odpowiednio ustawione.

Zobacz http://msdn.microsoft.com/en-us/library/f2ccy3wt.aspx, aby uzyskać informacje o środowisku VC++.

Answer 3

Twoim problemem jest to, że użytkownik nie korzysta z programu Visual Studio 2012, ale 2013. VS 2012 jest VS11 podczas VS 2013 jest VS12 i ścieżka "C: \ Program Files (x86) \ Microsoft Visual Studio 12.0" należy do VS 2013.

Podstawowym problemem jest jednak to, że VS 2013 jest zgodny z C99, co powoduje problemy w silniku V8 i javascriptcore.

Obecnie nie ma rozwiązania, ale ręczne poprawki.

Answer 4

Użyj oficjalna patch dla VS 2013 kompatybilności.

Answer 5

Dwie opisane powyżej łaty nie wystarczą. W moim przypadku, po zastosowaniu ich do Qt 4.8.5 Mam inny błąd:

Answer 6

@ Awaria AppDealer działa, jeśli musisz zastosować go do obu instancji pliku MathExtras.h. (Jeden w JavaScriptCore a drugi w Webkit Po że trafisz na problem HashSet kompilacji.

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

Obie te kwestie są poprawki z patch, które można znaleźć na this issue.
