quick stl vc.net question

[diehardii]

Hi everyone,

I'm writing an dll using directshow in VS.NET 2003. Because of this, I have to use the nodefaultlibraries and add libraries in manually. This works well most of the time, however I now wish to add vectors to my project, and I'm getting linker errors. I get the same error if I use the nodefault libraries option in another (less picky) dshow dll. Does anyone know what libraries I need to include for stl to function? I tried googling and searching the forums, but nothing came up. Thanks for the help.

~Steve You don't need any libraries for the STL that is included in VC++ to work. STL is template based, and all the code is inline in the header files.

Your problems are elsewhere, so please show us the errors that you're getting.

Hi Paul,
Thanks for the help. I am getting the following errors.

Linking...

If (in a simpler project) I remove the /NODEFAULTLIB it links. If I put that flag back, it fails with the exact same error messages as the more complicated project.

All I am including is

#include (vector)
and

std::vector(int) v;

(it doesn't seem as if the greater and less than symbols will show up in the code)
in another function. Thanks for the help.

Hmm... Maybe the new compilers have put the implementation code in seperate libraries (unlike VC 6.0)

Create a new, empty Win32 Console application (it must be a Windows Console app). Try the following (main.cpp):

#include < string >
#include < iostream >

using namespace std;

int main()
{
std::string s = "abc";
cout << s;
}

If this compiles and links, take a look at the settings used for the console application. I have written libraries using VC Net, and I see no problems with the STL.
