但若直接用 qtcreator 打开编译，则无错误
并且find -name libqt-mt* 也找不到其他版本的该文件
用qtcreator编译好的可执行文件，也找不到连接该lib文件

是否我使用qmake生成makefile时，需要加什么额外的参数，或者需要设置什么环境变量
QT5 QT --------------------编程问答-------------------- INCPATH = -I/usr/lib64/qt-3.3/mkspecs/default -I. -I. -I$(QTDIR)/include
这一行看上去你调用的qmake不是5.1.1的。试试指定完整路径运行qmake
/opt/Qt5.1.1/5.1.1/gcc_64/bin/qmake testQT.pro
补充：移动开发 , Qt
