请教高手一个问题，这几天我在学习VS2010结合QT编程，编译一个hello程序，提示找不到PDB文件，但编译是成功的，可以运行程序，请问怎么解决这个问题！
我在安装VS2010后，按照网上有人贴出来的方法编译QT源代码（http://www.cnblogs.com/elect-fans/archive/2012/03/29/2422816.html），在configure完成后，没有执行清理命令和不加参数-prex，这两个措施就是为了避免出现找不到PDB文件警告的，编译成功后，又继续安装了qt-vs-addin-1.1.10，打开VS2010，在其菜单中出现了QT选项，我打开一个hello例子进行编译，编译好后正常运行hello程序，但在编译状态栏中出现了很多找不到PDB文件的警告，请问高手们这是怎么回事，怎么解决这个问题！
谢谢
另外，我把状态栏中的警告信息贴在下面：
