Regarding Source file path, Image file path, symbol file path

WINDBG
1

Hi,
I am using WinDbg to analyze the crash due to a driver. I tried setting source path in different ways. Here are my final settings of WinDbg.

Source file path is set to the folders in C: which contain .pdb files.

Image file path is set to C:

The symbol file path is set to SRV*c:\symbols*http://msdl.microsoft.com/download/symbols at the command line of WinDbg.

But still I get the message that “Module load completed but symbols could not be loaded for *.sys”

Do I need to set symbol path to folders containing .pdb files?

What are the differences in source file path, symbol file path & image path?

I read the documentation in help file by windbg. But it didn’t clear the doubts.

Regards,
Harsha

Source path = source files (.c, .h, etc)

Symbol path = symbol files :slight_smile: (.pdb, .dbg)

Image Path = executable binary images (.exe, .sys, .dll, etc)

So your symbol path is currently set to get you the MS symbols, but not
the ones for your own project. An image path of ‘c:’ probably won’t be
useful, especially if the system running WinDbg is different than the
system which crashed. All of the paths are relative to the system
running WinDbg, not the target.

The best debug information to see why symbols aren’t loading is:

!sym noisy

.reload /f <module.ext>

Hi Jason,

Thank you for your reply. I set the corresponding path again. I got the output.

I sincerely appreciate your help.
