*im using VS.NET* Okay i got a lib project, it compiles fine and everything Now i include the lib in my dll project i get some weird errors. Both project are compiled under /Mld It looks like some sort of a missmatch or somthing but be damned if I can find out how to fix it. I tryed using "/NODEFAULTLIB:library" thing but I was kinda unsecure on where to put it, and also what syntax I should use on it. If anybody could be kind to explain to me why I get these erros, and how I can avoid them, and also how I can fix it as it is now without rewriting to much of my code i did be greatefull. Below is all the errors: *btw "core" is the name of the dll project im trying to compile*

Apparently, some of the components you''re compiling do not like your /Mld (LIBCD) flag. It''s possible that it''s overriden for some library files (MSVCP70D). Try compiling against another runtime.

The error says you have redefinition of functions/methods. Is your DLL linking against libraries that your LIB is itself linked against?

okay i tryed liking against some other run times and it still wont work.


Oluseyi:
I havent included any libs manualy in my lib project but prehaps
some other file im including does.

Is there anyway to make VS not include these functions ?


edit:
could it have anything to do with the way im declaring my namespace ?

i do it like this:


// .h
namespace foo
{
      class MyFoo
      {
            public:
               void Do();
      };
};

// .cpp
include .h

namespace foo
{
      void MyFoo::Do()
      {
            // some code
      }
};

Oluseyi:
okay thx for the help, it was that after all..
So after tricking a bit with the lib includes i got it working.


But now the $%Q%(Q*#&%_#(Q%& compiler wont generate a .lib only a .dll


So how are I suposed to set up a project where i dont want any precompiled headers, all i want is a empty progject(from the start, i will add my own files ofc) that generates a lib and a dll....
