[SOLVED]undefined reference to QBasicAtomicInt
-
I can compile my Qt project in Terminal bash but I'm having problems compiling with Qt Creator. here are some issue I've encounter:

When executing step 'Make'Please help me to solve this problem. thanks

If it compiles in terminal but not in QtCreator I would recommend comparing compile output from terminal and QtCreator (you have copy-paster latter here). Maybe you are using different Qt version in terminal and QtCreator. I believe QtCreator puts output to specific location (vs. compiling locally in terminal) - maybe cleaning up QtCreator output is all you need.
QBasicAtomicInt::deref() is part of QtCore and I see it included in linked library list (-lQtCore). As well I don't see compilation stage in your copy-paste only linking. Therefore I tend to believe that compilation stage was done with different Qt version.

Ahhh... Actually, my operating system crashes last time. and I've just restored my operating system to it's previous working state and it actually solved my problem. thanks again daliusd. :)
