public: static struct QMetaObject const QsciScintillaBase::staticMetaObject

hello I want to use QsciScintilla to make le editor
if I use Q_OBJECT ,it will make error lnk 2001 . if I remove Q_OBJECT ,it will build success。
the build tool is VS 2010 ,I had set the Configuration Manager release。 HOW CAN I DO IT

#include <Qsci/qsciscintillabase.h>
class DIY_QsciScintilla:public QsciScintilla
{
Q_OBJECT
public:
DIY_QsciScintilla(QWidget *parent = 0);
~DIY_QsciScintilla();
};

You should post the whole error message not just part of it.
Most probably you did not run qmake and a complete rebuild of your project after adding Q_OBJECT macro.
So, add Q_OBJECT, execute qmake and then rebuild your project (you can even delete the build directory before you do the rebuild if you're using shadow build).

And there is no need for so many exclamation marks.

So, you do not use qmake. Do you include the moc_*.cpp files in *.cpp files?

[raven-worx]

@xavieryang007
as already mentioned rerun qmake (on your .pro file) to rebuild the makefiles. So the moc files also get built into your binaries. Then the linker error should be gone.

Note: When using Visual Studio IDE the same is achieved automatically by the Qt plugin.

[xavieryang007]

I had already rebuild the makefiles.but It still has the same error in the project
