Wireshark · Wireshark-dev: Re: [Wireshark-dev] Issue loading a new plugin

[<gogrady@xxxxxxxxx>]

I built with VS 2008 and works in my wireshark version, but I also downloaded the official 1.0.5 release and it didn’t work in it. What are the Microsoft CRT dlls / where are they? Maybe ill try that. Though used the source from 1.1.2 or 1.1.3 so that could be my problem.

UFLF,

      Copying the Microsoft CRT dlls to the Wireshark directory (which as it turns out is recommend in the dev guide section 4.4.6.4) yields the following behavior. 

 


 


Again my plug-in works fine so long as I build Wireshark from source. Has anyone built a plugin with VS 2005 or greater and used that dll with the official Wireshark built release? Or does everyone just build there own Wireshark version? 

Thanks for  thelp,
Jim

ULFL,

      Thanks for help and fast response. The guide was very useful in
getting a build together. Building all of wireshark and executing that
with my plugin in place works fine. I only have an issue when I "install"
my plugin into the official release build.

So currently my only tests have been on my development machine. Your
correct the make file has no mt.exe reference. Copying the manifest into
the plugins location doesn’t seem to have an affect. I even installed the
c-runtime distrubtion files on my machine in case something was strange
there. Again no change. Later I will try your suggestion of copying the
runtime dlls just to see if the behavior changes.

Thanks for the help,
Jim

Hi!

This is the tricky part of the current Microsoft compiler toolchain :-(

As I've written most part of the Developer's Guide in that regard, I'm
still not satisfied with it's current state regarding the new Studios
(>V6). But I need some feedback, so please give detailed response :-)


Unfortunately, you didn't noticed if you tried to run your plugin on the
same (developer) machine where you've build it or on a different target
machine.

Two possible causes (at least I know of):
1) missing manifest infos
2) missing "C-Runtime "Redistributable" files"


1)
The most likely reason is that you need the manifest information. Have a
look at your Makefile.nmake you're using to build the ccs plugin. If it
doesn't contain a line like mt.exe (I'm certain it won't), you need to
copy the generated file ccs.dll.manifest along with your plugin,
otherwise it won't work.


2)
If you're trying to run it on a different target machine than your
developer machine, this is often a problem due to the missing "C-Runtime
"Redistributable" files" on the target machine. See:
http://www.wireshark.org/docs/wsdg_html_chunked/ChToolsMSChain.html#id4715
151

for details.


You can:

a) take the folder content of Microsoft.VC80.CRT (located somewhere in
the Studio dir c:\program files\...) and put the *content* of that dir
where the Wireshark.exe resides (or probably in the plugins dir, unsure
of the right location - please try it out and give feedback) or
b) install the redistributable pack as mentioned on the linked page
above. Make sure you have the right pack, depending if your Studio
you're using to build the Wireshark plugin has an installed SP1 or not
(if you find a different version number in the manifest file than in the
web page above, then *please* report it)

All in all, trying to run Wireshark plugins compiled with a different
msvcr than Wireshark core *might* work or cause trouble. Please report
success or strange behaviour ...



Regards, ULFL

P.S: Seems, that the plugin Makefile.nmake still don't contain the
mt.exe call, we really need to change this! Any volounteers?
