ubuntu下安装qt5.1

我的ubuntu版本：10.04 LTS

1.下载qt安装包： http://qt-project.org/downloads

  Qt 5.1.1 for Linux 32-bit

  下载后是.run文件，可以直接运行。一路下一步~

2.在命令行下运行/opt/Qt5.1.1/Tools/QtCreator/bin/qtcreator后提示

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

输入以下命令解决

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

3.再次运行/opt/Qt5.1.1/Tools/QtCreator/bin/qtcreator，提示

核心载入失败：/opt/Qt5.1.1/Tools/QtCreator/lib/qtcreator/plugins/QtProject/libCore.so：无法加载库/opt/Qt5.1.1/Tools/QtCreator/lib/qtcreator/plugins/QtProject/libCore.so：(/usr/lib/libstdc++.so.6：version 'GLIBCXX_3.4.15' not found (required by /opt/Qt5.1.1/Tools/QtCreator/lib/qtcreator/plugins/QtProject/../.././libQt5CLucene.so.5))

解决办法：

http://ftp.de.debian.org/debian/pool/main/g/gcc-4.7/

下载 libstdc++6-4.7-dbg_4.7.2-5_i386.deb

解压： ar -x libstdc++6_4.7.2-5_i386.deb && tar xvf data.tar.gz

把里面的libstdc++.so.6.0.17 拷贝到 /usr/lib/下,执行下面命令

cd /usr/lib
rm libstdc++.so.6
ln -s libstdc++.so.6.0.17 libstdc++.so.6

4.再次运行/opt/Qt5.1.1/Tools/QtCreator/bin/qtcreator，可正常打开qtcreator

ps:都弄好后，以后打开qtcreator就可以直接在应用程序->编程里打开了。
