将 dbg 符号文件加载到 WinDbg 中

Question

我有一个 DLL 的 MAP 文件，我正在尝试调试它。我使用 Map2Dbg-tool 将其转换为 DBG 文件并将其放入符号路径中。

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

然后我尝试使用!sym 噪音对其进行诊断，它告诉我 Windbg 会查找正确的符号路径，但仅限于 PDB 文件（mydll.pdb）。

有没有办法强制 Windbg 找到我的 DBG 文件？

编辑：

以下是一些进一步的信息：

Windbg中的符号搜索路径：

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

dbg 文件位于该目录中：

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

.重新加载输出：

> .reload /f cdmod.dll

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

Drag and Drop*.dbg 文件到模块的folder where exe exists
if表示而不是模块名称， 更改 dbg 文件的名称以匹配它，就像 do一样，windbg 应该加载您的 dbg 文件lm outputimagexxxxxxx
imagexxxxx.dbg.reload /fcv code symbols

预目录内容

    :\>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
