OllyDbg; Linking Source, Disassembly, and Execution.

[raleeper]

I am learning OllyDbg.  I have not been able to find a way to link the source code shown in one window with the disassembly shown in another, with execution poised to continue from the line highlighted in source and disassembly windows and numbered by eip.  For example.
--------
00401251 ff7508          push    dword ptr [ebp+8]
00401254 e8e7040000      call    testp!BeginPaint (00401740)
00401259 a3d0544000      mov     dword ptr [testp!hdc (004054d0)],eax
0040125e bf8a404000      mov     edi,offset testp!font1 (0040408a)              current position in disassembly window.
-------
dspl:   invoke   BeginPaint,wp_hWnd,ADDR ps      ;fills (ps) w/ defaults
   mov   [hdc], eax
   mov   edi, OFFSET font1                                                                          current position in source
-------
eip = 40125e
------

Is there a way to do this?

Thanks, Robert

Don't have a specific answer for you, but you'll need to assemble with the /Zd (and perhaps /Zi) option, and link with debugging info, for it to be able convert source lines to specific addresses. Then it's a matter of Olly being able to pull that from the debug symbols.

I found this posted in another forum by a member that is a member here too

Code Select Expand

C:\Masm32\Bin\ML.EXE /c /Zi/coff /Cp /nologo /I"C:\Masm32\Include" "MyProg.asm"
C:\Masm32\Bin\LINK.EXE /SUBSYSTEM:WINDOWS /DEBUG /VERSION:4.0 /LIBPATH:"C:\Masm32\Lib" "MyProg.obj"

apparently it generates a PDB file

I found an example that shows how to integrate OllyDbg's assembler and disassembler library into your Masm programs.

Originaly from here: http://www.winasm.net/forum/index.php?showtopic=482

This Requires this static library crtmt.lib ...I will upload it in the next post due to the limit of attachments

also, there is a recent update to Olly
you probably have it, but i will link it, anyways...

Thank you, clive.  I did omit /Zd  It might have taken me a while to realize that the problem might lie in the way I was assembling.
