交叉编译器： arm-linux-gnueabihf-gcc 

target borad ：am335x

./qt-opensource-linux-x64-5.9.3.run    //在ubuntu终端下运行，在crt下错误

• Install g++

Open a terminal and execute the following command to install g++:

sudoapt-getinstallbuild-essential

• Install generic font configuration library - runtime

Open a terminal and execute the following command to install the full runtime files for the generic font configuration library:

sudoapt-getinstalllibfontconfig1

• Configure a compiler

Launch Qt Creator. Go to Tools > Options. Click Build & Run and select tab Kit. Configure a compiler if it is not automatically detected.

• Install OpenGL libraries

Execute the following command to install OpenGL libraries:

sudoapt-getinstallmesa-common-dev

Note: Just installing the above-mentioned mesa-common-dev kit is not sufficient for more recent Ubuntu versions. Based on a comment in the Qt forum[1] an additional package needs installation. Execute following command:

sudo apt-getinstall libglu1-mesa-dev-y

linux下安装Qt5.7后添加qmake环境变量后出现错误 

执行

qmake-v

1

出现错误：qmake: could not exec ‘/usr/lib/x86_64-linux-gnu/qt4/bin/qmake’: No such file or directory

分析： 

qtchooser默认选择路径中没有指向qmake路径

解决方法：

cd/usr/lib/x86_64-linux-gnu/qt-default/qtchooservimdefault.conf

将第一行中的/usr/lib/x86_64-linux-gnu/qt4/bin/qmake 

替代为qmake的路径（我的安装路径/home/yqa1404/Qt5.9.3/5.9.3/gcc_64/bin ）
