Adding missing symbols to public symbols

NTDEV

Hi all,
I saw Scott’s responses below about how to add types to existing public symbols,

Title: !sysptes 4 and Windows 2003 R2 32bit Std/Ent

Title: Is it possible to add missing symbols to public symbols in a windbg debugging session?
URL: http://stackoverflow.com/questions/4278146/is-it-possible-to-add-missing-symbols-to-public-symbols-in-a-windbg-debugging-ses

So I added some types(e.g. _IMAGE_DOS_HEADER) to existing ntdll.pdb using Scott’s way,however,I got the following error messages:

ntdll.c
ntdll.c(4): error C2011: ‘_IMAGE_DOS_HEADER’ : ‘struct’ type redefinition
ntdll.c(32): error C2011: ‘_IMAGE_FILE_HEADER’ : ‘struct’ type redefinition
…

I know " _IMAGE_DOS_HEADER: ‘struct’ type redefinition" means ‘_IMAGE_DOS_HEADER’ has been defined,
However, I still got the following error message (it means ‘_IMAGE_DOS_HEADER’ doesn’t exist. ) when I am trying to see the IMAGE_DOS_HEADER structure using the ‘dt’ command

0:000> dt _image_dos_header
Symbol _image_dos_header not found.

If anyone know how to solve the problem, please tell me know. thanks.

Best regards,
Matt

If you don’t successfully compile your c file, nothing will get injected into the pdb. Fix your source file so that it compiles correctly.
