i am (It is one of the many binaries i maintain). i only use RELib when building it of course.
About the Q_DECL_EXPORT macro, it gets expanded like that (qglobal.h around line #1259 from the Qt 4.8.1 SDK):

// For the current issue, Q_OS_WIN is defined.
#if defined(Q_OS_LINUX) && defined(Q_CC_RVCT)
#  define Q_DECL_EXPORT     __attribute__((visibility("default")))
#  define Q_DECL_IMPORT     __attribute__((visibility("default")))
#  define Q_DECL_HIDDEN     __attribute__((visibility("hidden")))
#endif
// Look here, that's what gets defined when compiling RELibrary.
#ifndef Q_DECL_EXPORT
#  if defined(Q_OS_WIN) || defined(Q_CC_NOKIAX86) || defined(Q_CC_RVCT)
#    define Q_DECL_EXPORT __declspec(dllexport) // So Q_DECL_IMPORT is expanded to __declspec(dllexport) when compiling RELibrary, which is correct.
#  elif defined(QT_VISIBILITY_AVAILABLE)
#    define Q_DECL_EXPORT __attribute__((visibility("default")))
#    define Q_DECL_HIDDEN __attribute__((visibility("hidden")))
#  endif
#  ifndef Q_DECL_EXPORT
#    define Q_DECL_EXPORT
#  endif
#endif
// Look here, that's what gets defined when importing RELibrary.
#ifndef Q_DECL_IMPORT
#  if defined(Q_OS_WIN) || defined(Q_CC_NOKIAX86) || defined(Q_CC_RVCT)
#    define Q_DECL_IMPORT __declspec(dllimport)	// So Q_DECL_IMPORT is expanded to __declspec(dllimport) when importing RELibrary, which is correct.
#  else
#    define Q_DECL_IMPORT
#  endif
#endif
#ifndef Q_DECL_HIDDEN
#  define Q_DECL_HIDDEN
#endif

Hm ok. i have no idea what to do next... i'll see later.
If you have any other idea, i'd be very happy to get them from you.

Thanks a lot JonY,
