Qt5.1加载平台的插件xcb

i’m using ubuntu 12.04 and qt5.1. i compile my project with no

errors but when i try to launch my application on other machine i get

the following error:

Failed to load platform plugin "xcb". Available platforms are:

Annullato (core dump creato)

i add the required libraries to the ld_library_path:

Please download this package:

sudo apt-get install "^libxcb.*" libx11-xcb-dev libglu1-mesa-dev libxrender-dev

You can check why it don't work by using:

export QT_DEBUG_PLUGINS=1

and make run your app in terminal

if it dosen't work try

locate libxcb.so.1

and write this path in

export LD_LIBRARY_PATH=/MY_PATH:$LD_LIBRARY_PATH

Linux系统下Qt5编译好的程序在未安装Qt的系统下运行会报以下错误:

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

Reinstalling the application may fix this problem.

出现这个错误,主要是因为qt5为了在多平台下更方便移植,使用了一种新的技术-----platform abstraction system (QPA),而它中的库又依赖于Qt5中的一个库文件libQt5DBus.so.5,所以,只要打包时只要加上这个文件就可以了。

linux下qt5程序打包步骤如下

1、把以下7个库文件放到/usr/lib目录下

libQt5Widgets.so.5

libQt5Gui.so.5

libQt5Core.so.5

libicui18n.so.51

libicuuc.so.51

libicudata.so.51

libQt5DBus.so.5

2、拷贝Qt5安装目录中的platforms目录,使它和你的Qt程序同级目录

现在你可以双击你的程序运行了呵呵

用终端进入到qtcreator的安装目录,在其目录下执行 /qtcreator,看看终端上显示什么错误。

解决方案一:

版本问题,找一下之前的版本试一下,qt就是这个比较坑

解决方案二:

请把你的编译错误信息贴出来,大家好给你帮忙啊

解决方案三:

编译出错应该是QT4到QT5的问题..现在好了 可是连接数据有问题 界面打不开

解决方案四:

out of memory,内存不够了。还是你数据库连接字符串不正确

解决方案五:

1.什么叫“能运行倒是编译没过”编译都没过怎么运行的?

2.下载一个老一点版本的QT吧,你们交作业总不会限定你们使用QT的版本

解决方案六:

你搜索一下,看看升级qt版本会不会出现这样的问题啊,要是会出现可能会有相似的解决方案

解决方案七:

去百度查一下吧,要学会自己解决问题,csdn这里其实对这种很不明确的问题更不容易解决。
