All,

I've gotten rusty over the years and decided to create an application for myself to knock some of the rust off.
I've worked with projects that have used boost in the past and I'm wanting to use it as much as possible here.
I'm using VS2013 with the 64bit 1.57.0 boost libraries, so I have access to the newer c++ standard.

Can someone please show me how to get the following to compile?
Please ignore the functionality of the code, this is just something I quickly put together to demo my issue.

SafeList.h
#pragma once
#include <list>
#include <boost/thread/mutex.hpp>

template <typename dataType>
using CallbackType = bool(*)(dataType);

template <typename dataType>
class SafeList
{
public:
   SafeList() :
      list(),
      mutex()
   {
   }

   ~SafeList()
   {
      boost::mutex::scoped_lock scoped_lock(mutex);
   }

   void Add(dataType data)
   {
      boost::mutex::scoped_lock scoped_lock(mutex);
      list.push_back(data);
   }

   void Remove(dataType data)
   {
      boost::mutex::scoped_lock scoped_lock(mutex);
      list.remove(data);
   }

   void IterateList(CallbackType<dataType> callback)
   {
      boost::mutex::scoped_lock scoped_lock(mutex);
      for (int i = 0, bool flag = true; i < list.size() && flag; i++)
      {
         flag = callback(list[0]);
      }
   }

private:
   std::list<dataType> list;
   boost::mutex mutex;
};

FileList.h
#pragma once
#include "SafeList.h"
#include "File.h"
#include <boost/shared_ptr.hpp>

typedef boost::shared_ptr<File> FilePtr;

class FileList
{
public:
   FileList();
   ~FileList();
   void Add(FilePtr);
   void ProcessList();
private:
   bool ProcessItem(FilePtr);
   SafeList<FilePtr> safeList;
};

FileList.c
#include "stdafx.h"
#include "FileList.h"

FileList::FileList() :
safeList()
{
}

FileList::~FileList()
{
}

void FileList::Add(FilePtr filePtr)
{
   safeList.Add(filePtr);
}

void FileList::ProcessList()
{
   safeList.IterateList(this->ProcessItem); <-- This is the bad guy the compiler complains about and not sure how to resolve.
}

bool FileList::ProcessItem(FilePtr)
{
   return true;
}
