怎么使用QtCreator

​Starting: "/home/QtEmbed/bin/qmake" /root/Desktop/Calc/Calc/Calc.pro -r -spec /qws/linux-arm-g++ CONFIG+=declarative_debug
Failure to read QMAKESPEC conf file /qws/linux-arm-g++/qmake.conf.
Error processing project file: /root/Desktop/Calc/Calc/Calc.pro
21:10:44: The process "/home/QtEmbed/bin/qmake" exited with code 3.
Error while building/deploying project Calc (kit: ARM)
When executing step 'qmake'

以上是错误提示，应该使用了绝对路径，就是想问一下怎么修改问怎么修改
