本文介绍了解决Qt应用程序因找不到或加载XCB平台插件而启动失败的方法，包括创建符号链接和配置qt.conf文件的具体步骤。

1.This application failed to start because it could not find or load the Qt platform plugin “xcb”


The correct solution is running the following comand onto a terminal:

sudo ln -sf /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/ /usr/bin/

It creates the symbolic link it's missed.

2.软件打包后无法运行，单独运行提示XCB错误
解决方法：拷贝qt.conf 到/usr/bin目录里面


qt.conf内容如下


[Paths]
Prefix=../lib/Qt
Binaries=bin
Libraries=lib
Plugins=/usr/3rdparty/qt/plugins
Imports=imports
Qml2Imports=qml

打开Anaconda Navigator时候报错“this application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem”则找到F:\application\anaconda3\Library\plugins目录下的platforms文件夹，将该文件夹复制一份到安装目录下，即可打开。

Linux系统下在未安装Qt相关组件时运行用Qt5编译好的程序会报以下错误： This application failed to start because it could not find or load the Qt platform plugin "xcb". 出现这个错误，一般是因为缺少Qt5中的一个库文件依赖，即 libqt5dbus.so.5 打开终端用以下命令即可解决： sudo apt-get install libqt5dbus5 一般在再运行相关软件都可以成功了.

至此，could not find or load the Qt platform plugin "xcb" in "". 这个现象算是搞清楚了，和xcb和platform没关系，而是库文件引用路径的问题，检查路径即可。无法运行的ArtilleryAimLNX, 大部分都引用了同目录中的库，也就是 ../桌面/aim_exec_599/./这个目录。由于同目录的库被删了，现在可执行文件的库引用自动转向了/usr/lib/arrch64-linux-gun目录，路径里面没有奇怪的符号了。

按照指示的目录/usr/local/Qt6/plugins/platforms，发现有如下7个库，其中available的是其他6个库，libxcv.so虽然有但是不可用，看到libxcb.so库的metadata都没有解析出来，并且认为libxcb.so不是Qt的plugin，因为“Failed to extract plugin meta data”不过感觉跟libxcb.so关联的库有点少，和网上其他帖子一长串不太一致，这个不是安装Qt时候一起安装进来的，怎么会这样呢？libxcb在哪里呢？
