vs7 is a lot smarter at handling breakpoints than vs6 is, but it also won't automatically understand that an open .c file in your environment has symbols that match up with the symbols referenced in the symbols within a binary that's being debugged because it doesn't understand the symbol format used to compile those binaries. That's the trouble I ran into with vs7 and vs8, hence i'm using vs6.

It’s the .pdb files that it needs – they should have been created when 
the file was compiled. Is this a dynamically loaded plugin, or a 
statically linked object? MSVC 6 can be a bit rubbish at putting 
breakpoints in dynamically loaded code.
If you have MSCV 7.0 installed, you could try debugging under that – 
it seems to be a lot smarter about breakpoints (still build using MSVC 
6.0; the debug symbols are compatible).
Alternatively, there is a gratuitous hack that you can try if nothing 
else works.
At the head of the file you want to stop in, put:

#define _DEBUG

#include <crtdbg.h>

Where you want to stop, put:

_CrtDbgBreak();

Compile it up (if this fails, then I’d give up on this idea – it works for me in TShark where I tried it), then run in the debugger.
This will trigger a Win32 assert, and drop you into the debugger.

Obviously, don’t leave this in release code!

Well not quite - the compiler still disables breakpoint in the 
dissector, as it fails to see
the (symbolic) connection. Methinks you need .bsc files for that, 
which MSVC generates when you compile from the IDE, but apprently 
nmake does not.
any ideas?

    Thanks. Done all the wiki recommendations. I can now single/step
    debug main.c,

    but as you can imagine, my interest lies deep in one of the
    dissectors - e.g. packet-h263.c etc. How to I get to the situation
    I can single step through those?

    thanks

        The wiki tips page has a couple of useful sections on
        debugging and setting up browse info for MSVC.

        http://wiki.wireshark.org/Development/Tips

        I’ve also done it by creating a dummy static library project
        and using Wireshark as the “program” under the debug settings
        (useful for putting a breakpoint in start-up code).

        Cheers

        Hi,

        thanks for the willingness to assist.

        I did one thing : created an empty directory
        c:\wireshark-win32-libs

        and then ran the nmake -f makefile.nmake all

        with no further problems whatsoever.

        Since my install was a "clean" one (no previous wireshark
        builds etc.)

        I guess this may happen to others as well.

        If I may, one other short Q - the manual does not specify how
        I can use the MSVC IDE

        to debug wireshark, which was my main reason for building it.

        Is there a way to do that?

        thanks

            Hi,
            I have faithfully followed the Cygwin/packages
            installation, done the
            distclean and verify_tools stages. At the setup stage I
            get an error at the
            glib part:
            bash tools\win32-setup.sh --appverify cl link nmake bash
            bison flex env grep /usr/bin/find perl env python sed
            unzip wget
            Checking for required applications:
            cl: /cygdrive/d/PROGRA~1/MICROS~1/VC98/BIN/cl
            link: /cygdrive/d/PROGRA~1/MICROS~1/VC98/BIN/link
            nmake: /cygdrive/d/PROGRA~1/MICROS~1/VC98/BIN/nmake
            bash: /usr/bin/bash
            bison: /usr/bin/bison
            flex: /usr/bin/flex

            python: /cygdrive/c/ibmtools/python22/python
            sed: /usr/bin/sed
            unzip: /usr/bin/unzip
            wget: /usr/bin/wget
            ****** glib-2.6.6.zip ******
            No HTTP proxy specified (http_proxy and HTTP_PROXY are empty).
            Downloading gtk2.6/glib-2.6.6.zip into , installing into glib

            ERROR: Can't find glib
            So while I fully believe it "cleanly" works for many,
            obviously there is
            something missing in the manual.
            Any tips would be much appreciated.
            Thanks

            Hi,

            Just faithfully follow the developer guides guidelines on
            setting up your
            development environment, including cygwin and its tools,
            as well gathering
            the libraries.

            Tried it a couple of times, never failed on me.

            Thanx,
            Jaap
