使用SymChk獲取符號文件

方式一：類似下面的，遞歸式獲取某一目錄下所有文件的符號文件：（windbg的幫助文件及網絡上都能查到）

要使用 SymChk.exe 實用程序下載 Windows\System32 文件夾中所有組件的符號文件，請使用以下命令行命令：

symchk /r c:\windows\system32 /s SRV*c:\symbols\*http://msdl.microsoft.com/download/symbols

在此示例中：

• “/r c:\windows\system32”查找 System32 文件夾和所有子文件夾中的所有符號文件。
• “/s SRV*c:*http://msdl.microsoft.com/download/symbols”指定用於符號解析的符號路徑。在此例中，“c:\symbols”是將在其中從符號服務器複製符號的本地文件夾。
  
  

方式二：使用Manifest文件，這個少有人提及，References: http://msdn.microsoft.com/en-us/library/windows/hardware/ff560061(v=vs.85).aspx

Using a Manifest File with SymChk

n some cases, you might need to retrieve symbols for files that are on an isolated computer; that is, a computer that is either not on any network or is on a network that has no symbol store. In that situation, you can use the following procedure to retrieve symbols.

1. Run SymChk with the /om parameter to create a manifest file that describes the files for which you want to retrieve symbols.

2. Move the manifest file to a network that has a symbol store.

3. Run SymChk with /im parameter to retrieve symbols for the files described int the manifest file.

4. Move the symbol files back to the isolated computer.

Example

Suppose yourApp.exe is running on an isolated computer. The following command creates a manifest file that describes all the symbols needed to debug the yourApp.exe pocess.

C:\>SymChk /om c:\Manifest\man.txt /ie yourApp.exe

SYMCHK: FAILED files = 0
SYMCHK: PASSED + IGNORED files = 28

Now assume you have moved the manifest file to a different computer that is on a network that has access to a symbol store. The following command retrieves the symbols described in the manifest file and places them in the mySymbols folder.

C:\>SymChk /im c:\FolderOnOtherComputer\man.txt /s srv*c:\mysymbols*\\aServer\symbols

SYMCHK: myApp.exe             ERROR - Unable to download file. Error reported was 2
. . .
SYMCHK: FAILED files = 28
SYMCHK: PASSED + IGNORED files = 28

Now you can move the symbols to the isolated computer and use them for debugging.
