WinDbg: Couldn't resolve error at xyz!abc::func while setting breakpoint

I have attached WinDbg to a process.

When I use the command bp to set at break point. I get the following error:

bp xyz!abc::func
Couldn't resolve error at xyz!abc::func

What's wrong?

The output of lm m xyz is

start    end      module name 
4d6c0000 4dc59000 xyz (export symbols) C:\Program Files\path to xyz
Solution

  • When you did a lm m xyz you got

    start    end      module name 
4d6c0000 4dc59000 xyz (export symbols)      C:\Program Files\path to xyz

    where the term export symbols tells us it has only loaded the "public" functions of the DLL.

    To load the private symbols, do

    .sympath c:\path\to\your\pdb
.symfix+ c:\symbols
.reload /f
ld xyz

    And then do a lm m xyz again. If it still does not show "private symbols", repeat the same with a !sym noisy before and it'll tell you specifically what it could or could not load.
