注意事项(报错及解决办法)
报错1
configure运行报错，提示找不到动态库
# cat config.log

解决办法：
添加 -sysroot /home/cosmos/workspace/imx6ull_alientek/nfs/rootfs \ 选项,指定sysroot位置，把编译器的相关头文件和库文件拷贝到这里
报错2
头文件提示Qt requires C++11 support，qt高版本会检查编译器对C++11支持程度，这个报错表示当前编译器版本对c++11支持不完全。

解决办法1：升级gcc版本(由于arm-linux-gnueabihf-gcc是imx6ull的编译器，无法升级)
解决办法2：降低qt版本，请使用5.12.9
