Bug 51981 – [Qt] [Symbian] Fix building NPAPI support

• Component: Plug-ins
• Status: RESOLVED FIXED

[Laszlo Gombos]

The build failure reported is the following:

 compile    : WebKit2\Shared\Plugins\Netscape\NetscapePluginModule.cpp

   "Y:/epoc32/include/mw/QtCore/qsize.h", line 88: Error:  #338: more than one instance of overloaded function "operator*" has "C" linkage
         friend inline const QSize operator*(qreal, const QSize &);
                                   ^
   "Y:/epoc32/include/mw/QtCore/qsize.h", line 95: Error:  #800: this declaration may not have extern "C" linkage
     Q_DECLARE_TYPEINFO(QSize, Q_MOVABLE_TYPE);
     ^

It seems that the "C" linkage declaration is not used consistently and the following section of the npapi.h is included both with and without the "C" linkage declaration (depending the ordering of the include files).

#if defined(XP_SYMBIAN)
#include <QEvent>
#include <QRegion>
#endif

I'm trying to think who knows npapi.h these days.

I think this change is correct. A header file should not rely on extern "C" being set but declare it itself. Plus npapi.h already has the extern "C" declarations a bit further down the file.
