Dear llcwzg!

I have had the same problem, while I was compiling QSA.
I have tried to find QBasicAtomic in the Qt source, but I have found only QBasicAtomicInt and QBasicAtomicPointer classes.

So I tried to change QBasicAtomic to QBasicAtomicInt and it compiled successfully!

So my solution: In qsobject.h I have changed QBasicAtomic to QBasicAtomicInt.

BR,
