关于qmake报错

• qmake: could not find a Qt installation of ”或
• qmake: could not exec ‘/usr/lib/x86_64-linux-gnu/qt4/bin/qmake’或
• qmake: could not exec ‘/usr/lib/aarch64-linux-gnu/qt4/bin/qmake’ 

解决方法和常用命令

在aarch64-linux-gnu文件下不管是qt-default/qtchooser下的default.conf文件还是直接qtchooser下的 default.conf 都软连接到share/qtchooser目录下的qt4-aarch64-linux-gnu.conf
