感谢您的帮助编译前是否运行了“vcvars32.bat”?
VC++的环境变量似乎设置得不恰当
有关VC++环境的信息,请参阅
再见您的问题是您不使用Visual Studio 2012,而是使用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 然而,核心问题是VS2013与C99兼容,这导致V8引擎和javascriptcore出现问题
目前没有解决方案,只有手动修补。要修复“round”和“roundf”错误,请替换(第103行和第110行): 与: 要修复“signbit”错误,请使用以下宏(第128行)将其括起来:
\if\u MSC\u VER<1800
内联boolsignbit(double num){return\u copysign(1.0,num)<0;}
#恩迪夫
使用官方的VS 2013兼容性。上述两个补丁还不够。在我的例子中,在将它们应用到Qt 4.8.5之后,我遇到了另一个错误:

没有可执行此转换的用户定义的转换运算符,或者无法调用该运算符
.\wtf/HashSet.h(179):编译类模板成员函数“std::pair wtf::HashSet::add(void*const&)”时
解决方案是从Git Qt4存储库中获取3个文件:
/src/3rdparty/webkit/Source/JavaScriptCore/wtf/HashSet.h
/src/3rdparty/webkit/Source/JavaScriptCore/wtf/mathextas.h
/src/3rdparty/javascriptcore/javascriptcore/wtf/MathExtras.h
@AppDealer的awnser有效,如果您必须将其应用于
MathExtras.h
文件的两个实例。(一个在JavaScriptCore
中,另一个在Webkit
之后
您将遇到HashSet
生成问题

这两个问题都是可以在上找到的修补程序。更好的是,使用官方软件。我从
