接下来tutorial使用Visual Studio 2013编译Qt 4.8，但在运行nmake后我得到：

修复'round'和'roundf'错误替换（第103和110行）：

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

使用：

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

要修复'signbit'错误，请使用以下宏（第128行）将其括起来：

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

使用官方patch获取VS 2013兼容性。

答案 2 :(得分：2)

编译之前你运行过“vcvars32.bat”吗？ 似乎VC ++的环境变量没有适当设置。

有关VC ++环境的信息，请参阅http://msdn.microsoft.com/en-us/library/f2ccy3wt.aspx。

答案 3 :(得分：2)

您的问题是您不使用Visual Studio 2012而是2013. VS 2012是VS11而VS 2013是VS12，您的路径“C：\ Program Files（x86）\ Microsoft Visual Studio 12.0”属于VS 2013. < / p>

然而核心问题是VS 2013符合C99标准，导致V8引擎和javascriptcore出现问题。

目前没有解决方案，只能手动修补。

上面提出的两个补丁是不够的。在我的情况下，在将它们应用到Qt 4.8.5之后，我又遇到了另一个错误：

答案 5 :(得分：0)

@ AppDealer的awnser工作，如果你必须将它应用于MathExtras.h文件的两个实例。 （一个在JavaScriptCore，另一个在Webkit之后 您将遇到HashSet构建问题。 

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

这两个问题都是可以在patch上找到this issue的修复程序。
