I can create Makefile from qmake and can make my app by learning from Blackhawk's TextEditor. so I can create ezx app with my A780 library. But when I try to make with E680 ezx library (use sam's header files) my app can't start in E680 with this error.

./mf680: relocation error: ./mf680: undefined symbol: _ZN11ZMainWidgetC2ERK7QStr

how can i use ezx-crosstool with E680 library.
