我正在按照这个教程来使用Visual Studio 2013编译Qt 4.8，但是在运行nmake之后，我遇到了以下问题：

C:\Qt\4.8.5.src\src\3rdparty\javascriptcore\JavaScriptCore\wtf/MathExtras.h(103) : error C2491: 'round' : definition of dllimport function not allowed

使用官方补丁以支持VS 2013.

你的问题在于你使用的不是Visual Studio 2012而是2013。VS 2012为VS11，而VS 2013为VS12，而你的路径“C：\ Program Files（x86）\ Microsoft Visual Studio 12.0”属于VS 2013。

然而，核心问题在于VS 2013符合C99标准，这会导致V8引擎和javascriptcore出现问题。

目前还没有解决方案，只能进行手动修补。

在编译之前，你是否运行了“vcvars32.bat”？似乎VC ++的环境变量没有正确设置。

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

上述提出的两个补丁并不足够。在我的情况下，在将它们应用于Qt 4.8.5之后，我得到了另一个错误：

解决方案是从Git Qt4存储库中抓取三个文件：

/src/3rdparty/webkit/Source/JavaScriptCore/wtf/HashSet.h https://qt.gitorious.org/qt/mi-clone/raw/b45cc6bba9f85497eedf10cb5969d24273cb11db:src/3rdparty/webkit/Source/JavaScriptCore/wtf/HashSet.h /src/3rdparty/webkit/Source/JavaScriptCore/wtf/MathExtras.h https://qt.gitorious.org/qt/mi-clone/raw/b45cc6bba9f85497eedf10cb5969d24273cb11db:src/3rdparty/webkit/Source/JavaScriptCore/wtf/MathExtras.h /src/3rdparty/javascriptcore/JavaScriptCore/wtf/MathExtras.h https://qt.gitorious.org/qt/mi-clone/raw/b45cc6bba9f85497eedf10cb5969d24273cb11db:src/3rdparty/javascriptcore/JavaScriptCore/wtf/MathExtras.h

为了清晰起见，我在问题评论中重新链接了提议的补丁： https://qt.gitorious.org/qt/qtscript/commit/24d678ce9c3996f46d1069c2b1193e7ec1083fc8 和 https://qt.gitorious.org/qt/qtdeclarative/commit/a3f01331263eddbc502fb88734568ac38df5e316 - barbara.post

由于gitorious网站与补丁已经离线数天（正在迁移），是否有人可以将/src/3rdparty/webkit/Source/JavaScriptCore/wtf/HashSet.h的修补文件发送给我，因为这个错误在qt 4.8.6中仍然没有得到解决（尽管/src/3rdparty/javascriptcore/JavaScriptCore/wtf/HashSet.h可以编译）。非常感谢，Hermann。 - x y

@AppDealer的回答是正确的，如果你必须将其应用于MathExtras.h文件的两个实例。（一个在JavaScriptCore中，另一个在Webkit中）。之后，你会遇到一个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

这两个问题都可以通过补丁来解决，该补丁可以在此问题中找到。

要修复“round”和“roundf”错误，请替换（第103行和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)

为了解决“signbit”错误，请在以下宏的括号中加入它（第128行）：

To fix 'signbit' error enclose it with following macro (line 128):

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