请问大家，我的qte编译好了，qmake也有了，但是在用qmake -project命令时出错：
Failure to open file: /home/madfsl/arm/arm/examples/widgets/calculator//calculator.pro
Unable to generate project file.
哪位大侠告诉我这是什么原因啊，而且我直接用examples里面的makefile文件时，我用make，也出错：
Failure to open file: /home/madfsl/arm/arm/examples/widgets/calculator//Makefile
Unable to generate makefile for: calculator.pro
请大家帮帮我啊
