Am折叠这个教程来用visual 2013编译QT4.8，但是在运行nmake之后我得到：

若要修复“圆形”和“圆形”错误，请替换(第103和110行)：

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

通过以下方式：

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

若要修复“signbit”错误，请用以下宏(第128行)将其括起来：

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

使用官方的补丁来实现VS 2013的兼容性。

编译前运行"vcvars32.bat“吗？VC++的环境变量似乎没有得到适当的设置。

有关VC++环境的信息，请参阅VC++。

再见
