我的QT是4.7.4，creator是2.5.2，调试程序出现如下错误：
/home/xiaogao/test/efdes1/efdes1 启动中... /home/xiaogao/test/efdes1/efdes1: error while loading shared libraries: libphonon.so.4: cannot open shared object file: No such file or directory /home/xiaogao/test/efdes1/efdes1 退出，退出代码: 127 {1 ?} 但是我用locate 命令是可以搜到这个库的， /opt/qtcreator-2.5.2/lib/libphonon.so.4
/opt/qtcreator-2.5.2/lib/libphonon.so.4.4.0
