CUDA incompatible with Qt?

Including qtcore.h in my .cu (CUDA) file generates several internal Qt compile errors like the following:
c:\qt\4.8.0\include\qtcore../../src/corelib/global/qglobal.h(2152): error : more than one instance of overloaded function "swap" matches the argument list:
2> function template "void swap(T &, T &)"
2> function template "void std::swap(_Ty &, _Ty &)"
2> argument types are: (QByteArray::Data *, QByteArray::Data *)
2> detected during instantiation of "void qSwap(T &, T &) [with T=QByteArray::Data *]"
2> c:\qt\4.8.0\include\qtcore../../src/corelib/tools/qbytearray.h(161): here
As far as I now my code does not call swap, but I may be wrong.
Hi, and welcome to the Qt Dev Net!
[quote]As far as I now my code does not call swap[/quote]It looks like your code has
using namespace std, which causes a name clash between std::swap() and the other swap(). Move your #include out of the std namespace.
- Qt 4.8.0 is extremely old. Consider upgrading to Qt 4.8.6 (or Qt 5.3.1, if this is a new project)
- Including the whole of Qt Core may slow down your compilation. Instead of #include "qtcore.h", consider including the specific classes that you need.
