仅在交叉编译 Raspberry PI 的 QT 静态时进行 eglfs

我使用 Raspberry PI 交叉编译了 QT 静态

./configure -opengl es2 -opensource -confirm-license -release -static 
-prefix /usr/local/qt5static -hostprefix ~/raspi/qt5 -extprefix ~/raspi/qt5static 
-device linux-rasp-pi-novc-g++ 
-device-option CROSS_COMPILE=arm-raspbian-linux-gnueabihf- 
-optimized-qmake -reduce-exports 
-sysroot ~/raspi/sysroot 
-make libs -make tools -no-use-gold-linker -v

其中"novc"设备本质上与 linux-rasp-pi-g++ 相同，但没有来自/opt/vc 的包含或库。当我运行该程序时，它会全屏启动(由于 eglfs)，并且在以export QT_DEBUG_PLUGINS=1产生*

QFactoryLoader：：QFactoryLoader() 忽略 "org.qt-project.Qt.QPA.QPlatformIntegrationFactoryInterface.5.3" 自 插件在静态构建中被禁用 qt.qpa.plugin：找不到 Qt平台插件"安卓"在"此应用程序失败 启动是因为无法初始化Qt平台插件。重新安装 应用程序可能会解决此问题。

可用的平台插件有：eglfs，eglfs。

工厂装载机出现故障很好，但为什么只有 eglfs，其中两个在哪里？如何确保 xcb 是一个选项并且它是默认选项？

*我使用myapp -platform android因为我知道Android不在那里。来自sudo apt install qt的动态链接QT显示

可用的平台插件有：eglfs，linuxfb，minimal，minimalegl， 屏幕外，XCB。

我想从我的静态编译中得到它。这是我的 QPA 后端(我确实看到了 X11 的 eglfs，也许这就是我必须触发的......

我的hello_plugin_import有这个：

// static plugins specified using QTPLUGIN and QT_PLUGIN_CLASS.<plugin> variables.

更新。我注意到我可以在我的系统根中安装一堆libxcb软件包。我想如果我这样做，我可以让 xcb 显示为平台选项(甚至是默认平台选项？？但是这会搞砸我的静态编译吗？我的客户是否还需要安装所有这些库，或者 qmake 会做正确的事情吗？
