title: LNK2005: delete already defined error in VC++
body: <p>I am newbie to VC++, so please forgive me if this is stupid.</p>
  
  <p>I have got 7 solutions under one project. Six of these build static libraries which is linked inside 7th to produce an exe. The runtime configuration of all the projects is MultiThreaded Debug.
  sln which is used to produce exe is using MFC other slns use standard runtiem library. I tried changing those to MFC, but still I am getting the same error.
  All the six slns build successfully.
  When I try to build exe - get the follwoing error:</p>
  
  <pre><code>nafxcwd.lib(afxmem.obj) : error LNK2005: "void __cdecl operator delete(void *,int,char const *,int)" (??3@YAXPAXHPBDH@Z) already defined in tara_common.lib(fileStream.obj)
  </code></pre>
  
  <p>This is weird because tara_common is one of the libs that I generated and fileStream.cpp is file that is just using delete on a pointer.</p>
  
  <p>I built it in verbose mod, so I am attaching the output.</p>
