我尝试创建独立Web应用程序的步骤
主机PC是Ubuntu 14.04,64位操作系统。
Qt版本 - Qt5.6。
在虚拟Box Ubuntu 14.04,64位操作系统上进行测试。
应用程序在主机PC中正常运行。
我复制了所有与网络相关的文件＆amp;进程，平台相关文件和存在可执行文件的lib文件，然后我将库路径重定向到可执行文件的当前工作目录。
command used : chrpath -r ./lib AppName
然后当我运行应用程序时它打破了
This application failed to start because it could not find or load the Qt platform plugin "xcb".
Available platform plugins are: xcb.
Reinstalling the application may fix this problem.
Aborted (core dumped)
我在libqxcb.so上运行了ldd来查找依赖文件。
command : ldd libqxcb.so
我通过手动处理＆＃34;未找到的文件来解决这个问题＆＃34;到/ usr / lib路径
libQt5XcbQpa.so.5
libQt5DBus.so.5
libQt5Core.so.5
libQt5Gui.so.5
现在应用程序因以下错误而中断：
QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled

任何人都可以指导我解决上述问题。
提前致谢。
答案 0 :(得分：0)
您是否在虚拟机中运行了桌面版的Ubuntu？
您是否已启用＆＃34;启用3D加速＆＃34;在VM选项中。
您安装了Virtualbox视频驱动程序吗？
问题是QtWebengine需要OpenGL才能正常工作，这就是你收到此错误的原因：
QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled
