我正在尝试根据 http://wiki.qt.io/Building_Qt_5_from_Git 的描述构建Qt 5.4.1，但没有成功。有趣的是：我收到一个关于一些缺失符号的链接器错误，而不是一个关于可能来自缺少附加包的缺失库的错误！所以我假设Qt本身存在问题。这就是我正在做的：
使用 VS2013 在窗口下构建，配置以下选项：
-debug-and-release -release -force-debug-info -nomake tests -nomake examples -qt-zlib -qt-libjpeg -qt-libpng -opengl desktop -plugin-sql-sqlite
在成功使用"nmake"构建很长时间后，它最终失败并出现此错误：

为了更易于阅读，这是链接器错误消息的相关部分：
unresolved external symbol "public: static void __cdecl WebCore::TextCodecWin::registerExtendedCodecs(void (__cdecl*)(char const *,class WTF::PassOwnPtr<class WebCore::TextCodec> (__cdecl*)(class WebCore::TextEncoding const &,void const *),void const *))"(?registerExtendedCodecs@TextCodecWin@WebCore@@SAXP6AXPBDP6A?AV?PassOwnPtr@VTextCodec@WebCore@@@WTF@@ABVTextEncoding@2@PBX@Z2@Z@Z)
referenced in function "char const * __cdecl WebCore::atomicCanonicalTextEncodingName<unsigned char>(unsigned char const *,unsigned int)" (??atomicCanonicalTextEncodingName@E@WebCore@@YAPBDPBEI@Z)
有什么想法可以解决这个问题吗？
您可以在extendTextCodecMaps中将#if OS(WINDOWS)更改为#if OS(WINCE) in qtwebkit/Source/WebCore/platform/text/TextEncodingRegistry.cpp:301 in 。
查看ChangeLog-2012-10-02，它最初仅用于Windows CE。
