Tetrix Game error?

[khanhsk]

I'm doing tetrix game, when built the program, I get the following error message:

tetrixboard.obj:-1: error: LNK2001: unresolved external symbol "public: virtual struct QMetaObject const * __thiscall tetrixboard::metaObject(void)const " (?metaObject@tetrixboard@@UBEPBUQMetaObject@@XZ)

I don't know much about this announcement. Who knows what that error is, post on forums so I can reference.
I've posted together with source files. You should read it.tetrixpiece.cppmain.cppTetrix.protetrixboard.htetrixboard.cpp Thanks a lot !

Maybe you didn't include all files or you didn't run qmake.

I guess you need to moc the tetrixboard header. Try to clean and build the project again (make clean, qmake, make from console, or project->clean all, project->rebuild all in QtCreator).
Btw. you forgot to attach some files.

I've found a reason then, is the wrong project creation process. Thanks so much!
