荔枝派执行qmake后得到Makefile,接着执行make后报错，求老师们指点
错误信息如下

这个可以执行吗？
执行之后出现这个

/home/zhang/buildroot-2018.08.2/output/host/bin/arm-linux-g++再试一试这两个。
执行/home/zhang/buildroot-2018.08.2/output/host/bin/arm-linux-gcc
得到arm-linux-gcc.br_real: fatal error: no input files
compilation terminated.
执行/home/zhang/buildroot-2018.08.2/output/host/bin/arm-linux-g++
得到bash: /home/zhang/buildroot-2018.08.2/output/host/bin/arm-linux-g++: No such file or directory

用 ln 命令把arm-linux-gnueabihf-g++链接到 arm-linux-gcc
或者删掉前者，把后者拷贝为前者也可以
我执行了
sudo rm /usr/bin/qmake
sudo ln -s /home/zhang/buildroot-2018.08.2/output/build/qt5base-5.11.1/bin/qmake /usr/bin/qmake
在重新生成Makefile
再执行make
zhang@ubuntu:~/buildroot-2018.08.2/output/build/qt5base-5.11.1/examples/widgets/widgets/analogclock$ make

太奇怪了，还是报同样的错误

你的电脑有毒，删掉目录重新编译走一个，或者换台电脑。
应该不会有毒吧

我已经成功的编译出来可以执行程序analogclock，拷贝到TF卡之后顺利启动
# cat /dev/zero > /dev/fb0
# cat /dev/urandom > /dev/fb0
执行以上两条指令会黑屏和出现雪花点
但是执行
./analogclock -platform linuxfb
死活跑不起来，屏幕没有任何反应
麻烦再指导提示一下吧，谢谢
