Are you trying to statically link with Visual Studio? If so, does it help to make CUTELOGGERSHARED_EXPORT (in CuteLogger_global.h) empty?

[kevinlq]

Static compilation requires changing the export symbols. Maybe this modification is more appropriate.

CuteLogger_global.h

#if defined(QT_SHARED) || !defined(QT_STATIC)
#  if defined(CUTELOGGER_LIBRARY)
#    define CUTELOGGERSHARED_EXPORT Q_DECL_EXPORT
#  else
#    define CUTELOGGERSHARED_EXPORT Q_DECL_IMPORT
#  endif
#else
#  define CUTELOGGERSHARED_EXPORT
#endif
