JS_EXPORT incorrectly calls __declspec(dllexport) in static libraries this ends up meaning that a compiled EXE that brings in Webkit / QtScript ends up incorrectly exporting methods from JavascriptCore The offending lines are: #elif defined(WIN32) || defined(_WIN32) /* * TODO: Export symbols with JS_EXPORT when using MSVC. * See http://bugs.webkit.org/show_bug.cgi?id=16227 */ #if defined(BUILDING_JavaScriptCore) || defined(BUILDING_WTF) #define JS_EXPORT __declspec(dllexport) #else #define JS_EXPORT __declspec(dllimport) #endif #else #define JS_EXPORT #endif in QTDIR\src\3rdparty\JavascriptCore\API The end result is: Microsoft (R) COFF/PE Dumper Version 9.00.30729.01 Copyright (C) Microsoft Corporation.

Why define BUILDING_JavaScriptCore or BUILDING_WTF when not building a dynamic library?
