VS2010 C++ Debug 出现错误“Cannot find or open the PDB file”

按照MS的Debugger的说法：

   “We apologize if these messages are confusing, but is there any
functionality you are expecting that is not available in the debugger?
The symbol files (.pdb's) that cannot be found are the symbol files for
the Windows system .dll's, and the only reason that you would need these
is if you are trying to obtain complete callstacks including the
Windows components, or debug into the Windows system API's. If you need
the symbols, they are available from the Microsoft Public Symbol
servers by checking the "Microsoft Symbol Servers" box under symbol
settings (Tools -> Options -> Debugging -> Symbols).
”

 

照做，把下面Temp的路径改到自己想要的地方，Debug（会比较慢），取消掉MS的那个Symbols，底下的路径不动。

现在只是会解决了，但这Symbols是什么还需学习。
