我使用
为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'设备与linux-rasp-pi-g ++基本相同，但没有来自/ opt / vc的包含或库。当我运行程序时，它以全屏启动（因为eglfs），当用export QT_DEBUG_PLUGINS=1探测时产生*
QFactoryLoader :: QFactoryLoader（）忽略 “org.qt-project.Qt.QPA.QPlatformIntegrationFactoryInterface.5.3”自 在静态构建中禁用插件qt.qpa.plugin：找不到 Qt平台插件“android”在“”这个应用程序失败了 开始因为没有Qt平台插件可以初始化。重新安装 应用程序可以解决这个问题。
可用的平台插件有：eglfs，eglfs。
工厂装载机失败很好，但为什么只有eglfs，哪里有两个？如何确保xcb是一个选项，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的动态关联QT显示
可用的平台插件有：eglfs，linuxfb，minimal，minimalegl， 屏外，xcb。
我希望从我的静态编译中获得。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......）

更新。我注意到我可以在我的sysroot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（甚至默认平台选项??）。但这会搞乱我的静态编译吗？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？

我相信当您使用-static配置Qt时，您正在将平台插件添加到构建中，以后您无法在插件之间进行交换。我不确定这一点，但我一直走在那条路上，无法让qpa切换工作，只列出了一个平台插件。如果是某种方式，我很有兴趣听到它！
如果我对此更正，那么要使用xcb而不是eglfs，您需要使用configure的第一行重新配置Qt：
./configure -no-eglfs -qpa xcb -qt-xcb -opensource -confirm-license -release -static \
