Hello all,
- I've got Windows and I've got MS-VS 2010 Pro.
- I downloaded Source-Code for Wireshark v1.44.
- I downloaded CygWin and Perl and a bunch of tools and got them installed.
- After getting used to the makefiles and stuff I got wireshark
compiled. No details about that, since I'm not used to Makefile-driven
development.
- I can debug Wireshark from VS2010
Ok, this is how far I got without help.
Now I got into Wireshark and found the point that I want to change or
add something to. Specifically I want to have a little pop-up asking for
a number at a given point of code from within tap-rtp-common.c
So I got down to wrote some minor dialog (ugh... got to get used to gtk
development as well) and tried to compile. Naturally I got unresolved
externals, since what I had written hadn't even been compiled. So I went
looking for tap-rtp-common.c/h in all text files, since that's really
the only file that I'll call into my little dialog anyway. I found
tap-rtp-common.c/h was mentioned in ...\Wireshark\Makefile.common and in
...\Wireshark\CMakeLists.txt. So I went right into those and added my
newly created .c and .h files in there.
Now I get
NMAKE : fatal error U1073: "....obj" konnte nicht erstellt werden
Stop.
That's a bit odd, since it seems to be enough for tap-rtp-common.c/h.
Anyway - what did I miss? Where do I have to tell the Make-utility to
compile my stuff? It doesn't even give any syntax or other c-related error.
First of all:
tap-rtp-common is used by both the GUI and non-GUI variants of the software (Wireshark[GUI], tshark & rawshark[non-gui].
So trying to access gtk functions from tap-rtp-common isn't going to work.
IOW trying to link to gtk from stuff in any other directory than .../gtk is a non-starter. :)
What is it that you are trying to accomplish ?

Dear Bill,
thanks for your response and forgive the confusion with the mailing-addresses. I created this account specifically to handle all the wireshark load.
At the end of tap-rtp-common.c is a function called int rtp_packet_analyse(...).
Inside rtp_packet_analyse when you go down to /* Dynamic PT */ and go to the else of that if, there is a statement that says
clock_rate = 0;
Now, for the tests we are performing it is our wish to be able to enter the clock_rate at that very spot manually. That's what that mini-dialog is intended for. Just entering a number for the clock-rate.
It needs to work only in our little environment for our very specific purpose, so there's no need to find the "big-general-solution", unless it's even easier. For a starter, we're trying to get started with minimum effort.
Regards,
Carsten.
