I tried that and it doesn't it won't compile.
I must not be using it correctly.

Error "term does not evaluate to a function taking 0 arguments"
On the std::find_if line of code.

How do I use the predicate in this case?

Here is my code:

   // Make a copy of the provided buffer pointers and remove them as
they are matched with the requirements and stored
   std::vector<Buffer::SharedPtr> providedBuffers = vertexBuffers;

   // Go though the requirements and look for a match from the
provided buffers
   unsigned inputSlot = 0;

   while( !requirements.empty() )
   {
      // Get the first requirement
      std::string semanticName = requirements.front().SemanticName;

      // Search for a buffer with a matching semantic name in the
provided buffers
      CompareSemanticName comparator(semanticName);

      std::vector<Buffer::SharedPtr> found =
         std::find_if(providedBuffers.begin(), providedBuffers.end(),
comparator());

      if( found == providedBuffers.end() )
      {
         // Cannot provide the required vertex buffer type
         std::stringstream msg;
         msg << "The provided vertexs buffers do not contain a vertex
buffer type required "
             << "by the chosen technique."
             << "\nSemanticName: " << semanticName;

         throw BaseException(msg.str(),
                 "PassDescription::PassDescription(Pass & pass, const
std::vector<Buffer::SharedPtr> & vertexBuffers, const
Buffer::SharedPtr & indexBuffer, const D3D10_PRIMITIVE_TOPOLOGY
primitiveTopology)",
                 "PolygonSet3D.cpp");
      }

      // Loop under construction
   }
