Debugging in IA 64 environment.

WINDBG
1

Hi all,
I am trying to set a breakpoint on IA 64 machine to
debug a program. I have set the path for symbols to
point to my Debug directory.

But when set breakpoint it says debug symbols could
not be located and gives a error message saying “Code
not found, breakpoint cannot be set”.

What am I doing wrong?
Any idea will be of great help.

Thanx,
Manish

Hi John,
I tried but didnt work.

I am pasting here the response of the Windbg when I
load my application.

Symbol search path is:

And when I try to set the debug break point it gives
the error message as follows:

Symbol information for the current line could not be
found in the currently loaded symbols, Do you want the
debugger to load the remaining symbols ?

and after pressing Yes,
it says “Code not found, breakpoint not set”

Where am I going wrong?
One thing I dont understand why it says “WARNING:
c:\manish\study\awe\awe___win32_win64\awe.exe is not
accessible”.

Thanx,
Manish

Sounds like you have some kind of symbol problem.

The best way to troubleshoot symbol problems is to turn on noisy symbol loading. You can do this by adding -n to the command line or by typing “!sym noisy” in the debugger, followed by “.reload” With noisy loading on you will see what symbol files the debugger is looking for and where it is looking for them. You will also see error messages if the debugger refuses to load a symbol file.

Typically the problem will jump out at you. The 2 most typical problems are:
symbol path was not set to the correct location
symbol file does not match binary being debugged.

Hope this helps.
