I have build a Qt5 under a Linux 64bits.
Now I try to use it in QtCreator. But, even with the GCC x86_64 set and QMKSPECS set to linux-g++-64, the qmake build step indicates "qmake application.pro -r -spec linux-g++". And of course, it does not work at link time because Qt5 libs are 64bits...
Anyone has the same problem.
