Question

我有一个我正在尝试调试的DLL的MAP文件。我使用Map2Dbg工具将其转换为DBG文件，并将其放入符号路径。

发出 .reload / f mydll.dll 但不起作用，会发生符号加载错误。

然后我尝试用！sym noisy 来诊断它，它告诉我Windbg查找正确的符号路径，但仅用于PDB文件（ mydll.pdb ）。

有没有办法强制Windbg找到我的DBG文件？

修改

以下是其他一些信息：

Windbg中的符号搜索路径：

> .sympath
e:\code-factory\symbols;cache*;SRV*http://msdl.microsoft.com/download/symbols

dbg-file位于该目录中：

e:\code-factory\symbols> dir /b
cdmod.dbg
cdmod.map
...

.reload输出：

> .reload /f cdmod.dll

DBGHELP: e:\code-factory\symbols\cdmod.pdb - file not found
DBGHELP: e:\code-factory\symbols\dll\cdmod.pdb - file not found

Drag and Drop * .dbg文件到folder where exe exists
如果模块的lm output表示imagexxxxxxx而不是模块名称更改dbg文件的名称以匹配它imagexxxxx.dbg do .reload /f和windbg应该使用cv code symbols

加载dbg文件

前目录内容

    :\>dir /b
    msgbox.exe
    msgbox.map  < created via ida produce map

将地图转换为dbg

    :\>map2dbg msgbox.exe  lucian wischik utility
    Converted 7 symbols.

发布目录内容

    :\>dir /b
    msgbox.dbg
    msgbox.exe
    msgbox.map

在windbg中加载exe

    :\>windbg msgbox.exe    
0:000> lm 
start    end        module name
00400000 00404000   image00400000   (deferred) 

0:000> .reload /f
Reloading current modules
ERROR:Module load completed but symbols could not be loaded for image00400000 

0:000> lm e
start    end        module name
00400000 00404000   image00400000   (no symbols)

$ rename the msgbox.dbg to image00400000.dbg

重命名dbg文件

    :\>ren msgbox.dbg image00400000.dbg        
    :\>dir /b
    image00400000.dbg
    msgbox.exe
    msgbox.map

将cv代码符号信息加载到windbg中的符号文件

0:000> lm e

0:000> lm m i*
