Should I give you a fish or teach you fishing?

You've probably missed a include, either stlport or wtl. Mine looks like this:
(VC++ Directories -> Include files)
F:\DCPlusPlus\includes\wtl\wtl75_4291\include
F:\DCPlusPlus\includes\stl\DCPlusPlus-STLPort-4.6.2

And then of course....google is always your friend : http://www.google.se/search?hl=sv&q=unr ... ning&meta=

well, if it is not a problem for You i would like to get fish;)
But serious, did You (or anyone) know where is bug, all error messages contain the same symbol "unsigned long __cdecl _exception_code(void)" (?_exception_code@@YAKXZ) so i think its some trivial mistake but i can't find it.
Once again help please /*and of course forgive my english*/

Do you have WTL and STL properly included? Which versions of WTL and STL?

Exceptions are used all over the DC++ source. Also, to be perfectly clear, you are using the DC++ source code from this site, not another client based on DC++?

thisOne · Post by **thisOne** » 2004-12-27 18:13

Yeap, all of my _DC_source_stuff_ come from this site. I've got still 31 f...n unresolved external errors, and i mightily desire to rummage DC.

Guitarm · Post by **Guitarm** » 2004-12-27 18:58

Ok, are you absolutely sure you have the right versions of ATL and STL for the version of DC++ you are trying to compile?. And again - are you sure you have included them the right way?

I guess you meant wtl here.

In the error messages, there are not anythin like First referenced in somefunc(someparam) at the end of the error message? ( Check the build window instead of the task window if you did that before as the build window sometimes contains more info )

hmmm... I'm not sure i have the right ver of libs. I just download them together with dc source and unpack into separate dirs. Output window contain:

Try rebuilding. And perhaps switching from a Release/Debug build to a Debug/Release one (and then rebuilding).

thisOne · Post by **thisOne** » 2004-12-28 14:25

I rebuild it many times and combine with release/debug and almost all available project options. I even try many real stupid things like

Code: Select all

#define _exception_code(void) NULL

or compile and include library with this function doing nothing

, yes i know its dumb

, but i really want to make it works.
Any ideas

TheParanoidOne · Post by **TheParanoidOne** » 2004-12-28 16:58

Long shot. "unsigned long __cdecl _exception_code(void)" is defined in the file $(VCInstallDir)include\excpt.h.
Do you have have this file? Is it appropriately referenced in Visual Studio?

Guitarm · Post by **Guitarm** » 2004-12-28 17:53

Good point TPO

joakim_tosteberg · Post by **joakim_tosteberg** » 2004-12-29 02:15

If the .h file was missing it wouldn't be able to find the function at all which more probably would result in compile time errors instead of link time. I would rather say that there is some library that should be imported but which isn't.

thisOne · Post by **thisOne** » 2004-12-30 05:45

I already compile my dc

. If someone is interest how : I defined this function just return;
Maby its not properly but anyway it works. Thanks for help

Post by **ullner** » 2004-12-30 09:08

You should not need to add or alter any code when first compiling DC++.

For compiling, you need to:
Include WTL
Include STL
Add natupnp.h (if not allready added) to the includefiles of VS.NET 2003
Have Python installed

If you have any unexplained behavior down the road, this may be why.
