MOC Linking Errors from MSVC 2015
I've been using cmake to generate a MSVC project file. The entire project is written in C++ and makes use of signals and slots. I've enabled the "AUTOMOC" option cmake provides and it generates the necessary "moc_filename.cpp" files. I've included the generated files at the bottom of each implementation file for each class. The project compiles, but fails on the linking step with these types of errors:
windows_gui_automoc.obj : error LNK2005: "private: static void __cdecl RemoteWindow::qt_static_metacall(class QObject *,enum QMetaObject::Call,int,void * *)" (?qt_static_metacall@RemoteWindow@@CAXPEAVQObject@@W4Call@QMetaObject@@HPEAPEAX@Z) already defined in moc_RemoteWindow.obj moc_ServerTab.obj : error LNK2001: unresolved external symbol "public: static struct QMetaObject const QWidget::staticMetaObject" (?staticMetaObject@QWidget@@2UQMetaObject@@B) TabDialog.obj : error LNK2001: unresolved external symbol "public: static struct QArrayData const * const QArrayData::shared_null" (?shared_null@QArrayData@@2QBU1@B)
Any ideas as to what might be causing this?
If you use automoc then you do not have to include the moc_.cpp files in your source files.
The moc_.cpp files are compiled and linked automatically.
