arghhh.  Sorry, edit fail... deleted :-).

Not sure why you're loading the shader like this:

  ifstream FragmentShaderStream(Fragment_file_path, std::ios::in);
  if(FragmentShaderStream.is_open())
  {
		string Line = "";
		while(getline(FragmentShaderStream, Line))
			FragmentShaderCode += "\n" + Line;
			FragmentShaderStream.close();
   }

I mean getting a line and then appending a newline seems a bit pointless.  I would write something like:

/* static */
void
FileReader::Read(std::string const & path, std::string & output)
{
[indent=1]
// Open stream.[/indent]

[indent=1]std::ifstream stream(path, std::ios::in);[/indent]

[indent=1]// Read into buffer.[/indent]

[indent=1]std::stringstream buffer;[/indent]

[indent=1]buffer << stream.rdbuf();[/indent]

[indent=1]// Assign result.[/indent]

[indent=1]output = buffer.str();[/indent]

[indent=1]stream.close();[/indent]
}
