Gracias por cualquier ayuda

Answer 1

¿Has ejecutado "vcvars32.bat" antes de compilar? Parece que las variables de entorno de VC ++ no están configuradas adecuadamente.

Consulte http://msdn.microsoft.com/en-us/library/f2ccy3wt.aspx para obtener información sobre el entorno de VC ++.

Answer 2

El trabajo de Awnser de @ AppDealer, si tiene que aplicarlo a ambas instancias del archivo MathExtras.h . (uno en JavaScriptCore y otro en Webkit Después de eso, se encontrará con un problema de compilación HashSet .

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

Ambos problemas son soluciones con el parche que se puede encontrar en este tema .

Answer 3

Los dos parches propuestos anteriormente no fueron suficientes. En mi caso, después de aplicarlos a Qt 4.8.5, recibí otro error:

La solución fue tomar 3 archivos del repositorio de Git Qt4:

Answer 4

Para corregir los errores ''round'' y ''roundf'', reemplace (líneas 103 y 110):

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

con:

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

Para corregir el error ''signbit'' enciérrelo con la siguiente macro (línea 128):

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

Answer 5

Su problema es que no utiliza Visual Studio 2012 sino 2013. VS 2012 es VS11 mientras que VS 2013 es VS12 y su ruta "C: / Archivos de programa (x86) / Microsoft Visual Studio 12.0" pertenece a VS 2013.

Sin embargo, el problema principal es que VS 2013 es compatible con C99, lo que causa problemas en el motor V8 y javascriptcore.

Actualmente no hay solución, pero el parche manual.

Answer 6

Use el parche oficial para compatibilidad con VS 2013.
