I.MX6ULL移植Q5.12.9报Could not load the Qt platform plugin "linuxfb" in "/usr/lib/arm-qt/plugins" even though it was found.错误

根据正点原子的移植教程移植完成并成功运行,这是前提。
但是自己用buildroot做的rootfs,把qt的库放到里边,运行测试程序缺报错

qt.qpa.plugin: Could not load the Qt platform plugin "linuxfb" in "/usr/lib/arm-qt/plugins" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: linuxfb, minimal, offscreen, vnc.

网上查找方法,在/etc/profile中添加对qt的调试信息的输出使能

source /etc/profile后,重新执行测试程序 一下是打印信息

QFactoryLoader::QFactoryLoader() checking directory path "//platforms" ...

可以看到是libts.so.0的问题,对比之前正确启动了的rootfs,发现在有问题的rootfs的lib文件夹中缺少libts.*库,所以全部复制进去,再测试,就好了。

我在用buildroot构建rootfs的回收,没有选ts相关的选项,所以lib中没有libts相关的东西。
