問題描述

我重新安裝了 ubuntu 14.04、Qt 5.4.1 和 Qtcreator.

I reinstalled my ubuntu 14.04 and Qt 5.4.1 and Qtcreator.

Qt 5.4.1 是從源代碼構建的，帶有-opensource -nomake-test -nomake-example"配置選項.

Qt 5.4.1 was built from source with "-opensource -nomake-test -nomake-example" configure options.

當我在 QtCreator 中打開一個舊項目并構建它時，一切正常.

When I open an old project in QtCreator and build it everything's OK.

但是當我運行這個項目時它顯示:

But when I run this project it shows:

此應用程序無法啟動，因為它無法找到或加載 Qt 平臺插件xcb".

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

可用的平臺插件有:linuxfb、minimal、offscreen、xcb.

Available platform plugins are: linuxfb, minimal, offscreen, xcb.

重新安裝應用程序可能會解決此問題.中止(核心轉儲)

Reinstalling the application may fix this problem. Aborted (core dumped)

所以我用谷歌搜索了這個問題并嘗試了一切.我安裝了所有軟件包(libxcb 系列)但沒有任何幫助！

So I googled this problem and tried everything. I installed every packages (libxcb series) but nothing can help!

請有人幫助我...

我試過你的方法.

當我在 platform 目錄中運行 ldd 命令時，它顯示:

When I run ldd command in platform directory, It shows:

你可以看到什么都沒有丟失.實際上我已經在名為 libqxcb.so 的平臺目錄中創建了一個軟鏈接.之前我的平臺目錄下沒有libqxcb.so.

You can see that nothing is missing. And actually I have made a softlink in the platform directory called libqxcb.so. There was no libqxcb.so in my platform directory before.

當我對我的可執行文件運行 ldd 命令時.表明:

And when I run ldd command to my executable. it shows:

當我執行這個文件時你可以看到錯誤.

And you can see the error when I execute this file.

推薦答案

對于類似的問題，在我的情況下，我解決了:

For a similar issue, in my case I solved with:

export QT_PLUGIN_PATH=<qt base path>/plugins
