Simple Program

[KezRst]

I made this program to duplicate an error I'm receiving. When I run the program I receive:

Snake.obj : error LNK2019: unresolved external symbol
 __imp___CrtDbgReportW referenced in function "public: __thiscall 
std::_Vector_const_iterator<short,class std::allocator<short> 
>::_Vector_const_iterator<short,class std::allocator<short> >(short *,class 
std::_Container_base_secure const *)" 
(??0?$_Vector_const_iterator@FV?$allocator@F@std@@@std@@QAE@PAFPBV_Container_base_secure@1@@Z)

I've looked up information about LNK2019 and LNK2001 in multiple forums, on MSVC, and other websites, but the information didn't really seem to apply.

#pragma comment(lib, "SDL.lib")
#pragma comment(lib, "SDLmain.lib")
#pragma comment(lib, "SDL_TTF.lib")
#pragma comment(lib, "SDL_image.lib")

#include <vector>
#include <string>
#include "SDL.h"
#include "SDL_TTF.h"
#include "SDL_image.h"

using namespace std;

class Test {
  public:
    Test();

  private:
    vector<vector<short>> myvar;
};

Test::Test()
: myvar ()
{
  //Uncommenting these two lines, 
  //it will report LNK2001 instead of LNK2019

  //vector<short> test (2, 10);
  //this->myvar.push_back(test);

  myvar.resize(1);
}

SDL_Event testevent;

int main( int argc, char* args[] ) {
  bool genericloop = true;

  while( genericloop ) {
    SDL_PollEvent( &testevent );
    if ( testevent.type == SDL_QUIT ) genericloop = false;
  }
  return 0;
}

Does anyone have any ideas? Thanks!

Hey Aaron. First I'll say that I'm no expert (you probably know more than I do about this)...I'm just hoping to learn something too (and nobody else is replying). You may have already seen it, but I found what looks to be a very relevant thread on MSDN:

http://social.msdn.microsoft.com/Forums/en/vcgeneral/thread/5e126c79-77f3-4d50-a47f-a9ce35cff0a4

If that doesn't help, would I be right in saying that the linker errors have nothing do with the SDL-related code, but rather with std::vector?

I built the following code without a problem (same as yours, but with all SDL references taken out). Perhaps you could try just building this (just an idea)...

#include <vector>
#include <string>

using namespace std;

class Test 
{
  public:
    Test();

  private:
    vector<vector<short>> myvar;
};

Test::Test()
: myvar ()
{
  vector<short> test (2, 10);
  this->myvar.push_back(test);

  myvar.resize(1);
}

int main( int argc, char* args[] ) {
	Test mytest = Test();
  bool genericloop = true;
...
}

It probably won't help, but I thought I'd give it a shot. I'll keep an eye on this thread so that I can learn what's going on here too...
