Error LNK2019: Unresolved external character "toString (int)"

Environment: Windows XP. Visual Studios 2010. Language - C ++.

I ran into the following link error and ran out of ideas on how to fix this problem. I have a project (CnD Device) that refers to 2 projects (Messages and Carbon) that my group manages. I tried to find project properties between three projects

enter tcp_driver.obj : error LNK2019: unresolved external symbol "class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > __cdecl toString(int)" (?toString@@YA?AV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@H@Z) referenced in function "protected: bool __thiscall Tcp_Driver::readMessage(void)" (?readMessage@Tcp_Driver@@IAE_NXZ)

I believe this problem is due to the fact that I am not snapping to a string that is in the C ++ standard library. I have looked through the property list over and over again. Below are some of the properties that I believe are critical to this problem.

CnD Device Properties Information:

  • Configuration Type Dynamic .dll
  • Using MFC Using MFC in a Common DLL
  • Using ALT Not Using ALT
  • Character Set Use multibyte character set
  • Multithreaded DLL (/ MD) Runtime Library
  • Additional dependencies msvcprtd.lib, Carbon.lib, BUFFER_API.lib, BUFFER_FRAMEWORK.lib, Messages.lib
  • Ignore all default libraries No

Message Properties:

  • Configuration Type Static Library (.lib)
  • Using MFC Using MFC in a Common DLL
  • Using ALT Not Using ALT
  • Character Set Use Unicode Character Set
  • Multithreaded DLL (/ MD) Runtime Library
  • Additional Dependencies
  • Link Library Dependencies None

Carbon Information:

  • Configuration Type Static Library (.lib)
  • Using MFC Using MFC in a Common DLL
  • Using ALT Not Using ALT
  • Character Set Use Unicode Character Set
  • Multithreaded DLL (/ MD) Runtime Library
  • Link Library Dependencies None
