你可以创建一个小的Qt Widgets应用程序,并在其中设置平台插件为"offscreen"。 例如,在Linux上,你可以在应用程序启动前设置环境变量QT_QPA_PLATFORM为offscreen: bash export QT_QPA_PLATFORM=offscreen 然后运行你的Qt应用程序,查看是否还会出现相同的错误。 检查环境变量: 确保环境变量QT_QPA_PLATFORM_PLUGIN_...

offscreen: 无显示后端。 vnc: 通过VNC协议远程显示。 Qt程序无法连接到X服务器 最终解决办法: 如果Qt程序无法连接到X11服务器,需要设置DISPLAY环境变量,并检查X权限和服务器状态: export DISPLAY=:0export QT_QPA_PLATFORM=linuxfb# 这样adb 和 ssh都可以执行qt程序,饼显示到display 桌面上。# xhost +SI:local...
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb. Aborted (core dumped) 根据问题描述,虽然能够找到但是不能加载Qt平台插件“xcb”,虽然接下来又说重新安装可能能够解决,这个可能的话,还是尽量作为最下的选择吧。
