Right now, both libraries use QWEBKIT_EXPORT, which is incorrect. This is important for platforms that use different macros for Q_DECL_EXPORT and Q_DECL_IMPORT, notably Windows but also on ELF platforms with protected visibility. I really have no clue how you managed to compile WebKit on Windows with this bug. I recommend leaving QWEBKIT_EXPORT for QtWebKit and creating QWEBKITWIDGETS_EXPORT for QtWebKitWidgets. Also note that they need to be controlled by differen macros. qmake in Qt 5 automatically creates one such macro per library being built: QT_BUILD_${libname in uppercase}_LIB. That is, QT_BUILD_WEBKIT_LIB and QT_BUILD_WEBKITWIDGETS_LIB. In Qt 4, that is not automatic, so the .pro files need to have those two macros in DEFINES +=. Also note that there are some Q_DECL_EXPORT uses directly in header files in WebKit/WidgetSupport/InitWebKitQt.h. That's only correct if this header is included from one single library. If it's included from two or more libraries, it needs to use the proper lib-specific export macro. So my recommendation is to do it. 781164 1 thiago 2012-12-02 23:26:29 -0800 Patch is on 103844. Keeping this open for the description and additional work (the InitWebKitQt.h)
