问题1：安装好qtcreator后，发现点击桌面Qt Creator图标没有反应，进入bin目录， ./qtcreator 。终端提示
[email protected]:~/qtcreator-2.5.0/bin$ ./qtcreator ./qtcreator: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
分析是缺少相应的动态库，后查百度，其动态库对应的安装包是
lib32stdc++6，于是sudo apt-get install lib32stdc++6
问题2：解决上一个问题之后，再次 ./qtcreator,报如下错误 。
./qtcreator: error while loading shared libraries: libgthread-2.0.so.0: cannot open shared object file: No such file or directory
于是通过dpkg查找动态库对应的包
[email protected]:~/qtcreator-2.5.0/bin$ dpkg -S libgthread-2.0.so.0 libglib2.0-0:amd64: /usr/lib/x86_64-linux-gnu/libgthread-2.0.so.0.4800.2 libglib2.0-0:amd64: /usr/lib/x86_64-linux-gnu/libgthread-2.0.so.0
于是sudo apt-get install libglib2.0-0:i386安装 （后面需要加i386，查百度说，i386是intel32位的统称）
。。。。。。。此处省略三百安装。。。。后通过 ldd命名查看qtcreator所依赖的库
[email protected]:~/qtcreator-2.5.0/bin$ ldd qtcreator linux-gate.so.1 => (0xf7771000) libExtensionSystem.so.1 => /home/book/qtcreator-2.5.0/bin/./../lib/qtcreator/libExtensionSystem.so.1 (0xf773a000) libAggregation.so.1 => /home/book/qtcreator-2.5.0/bin/./../lib/qtcreator/libAggregation.so.1 (0xf7733000) libQtGui.so.4 => /home/book/qtcreator-2.5.0/bin/./../lib/libQtGui.so.4 (0xf6bb8000) libQtNetwork.so.4 => /home/book/qtcreator-2.5.0/bin/./../lib/libQtNetwork.so.4 (0xf6a5b000) libQtCore.so.4 => /home/book/qtcreator-2.5.0/bin/./../lib/libQtCore.so.4 (0xf6756000) libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xf671f000) libstdc++.so.6 => /usr/lib32/libstdc++.so.6 (0xf65a8000)
后经过安装无数库，终于成功安装了qtCreator。
主要涉及的命令有 分析库依赖安装包：
dpkg -S xxx
软件安装命令：sudo apt-get install xxx:i386 （注意后面需要加
i386）
