windbg中symbols设置的问题

Question

用windbg和vmware进行调试驱动。可在symbols下载时老是出错：
*** ERROR: Module load completed but symbols could not be loaded for vnet.sys
vnet.sys就是我的驱动。
用lm看。发行vnet.sys（no symbols）。
好像.pdb文件不对，可是我用vc编译驱动是正确的阿。
而且我一直都是正确的，突然在一次vc编译之后就出现这个问题了，之后再怎么编译都是错误

Answer 1

用重新编译的sys，重现问题，生成dump，同时把同一次编译出来的pdb放到windbg寻找的路径中

Answer 2

pdb文件必须和你生成dump所用的sys文件严格匹配。如果你修改了再重新编译，pdb文件和你dumnp内部的.sys文件的版本已经不匹配了，因此就报错了

Answer 3

我是在刚调试,load symbol的时候.还没开始加载驱动呢.
还没有生成dump文件呢.
dump文件都是在蓝屏后出现的吧

Answer 4

重点不在于何时生成dump，而是你在windbg载入那个sys文件时，所用的pdb和你dump中的sys模块是不是匹配。从错误信息看，至少找不到，而且你时重新编译后开始出现这个问题的，那么显然时不匹配

Answer 5

所谓dump和你遇到的在线调试的方式的内存是一致的。dump只是内存的一个静态拷贝。因此说dump需要，也就是等于你在内存中载入那个sys也需要btw，dump随时可以生成，你不必要等蓝屏再生成

Answer 6

我是把整个objchk文件夹删了之后重新编译的,还是会出现那个错误

arong:
我不太懂那个dump从哪看到呢??
是vmware里看?
