[ROOT] Error: Symbol TSdaqGuiFactory is not defined in current scope FILE: LINE:0

Hi ROOT-talkers,

I've succesfully built a library called 'libsmt_ped_tools.a' containing 
various ROOT-based classes, one of which is called TSdaqGuiFactory 
(inherits from TGuiFactory). This library was linked in when I built the 
following piece of code:

==================================================================
#include "smt_ped_tools/sdaqbrowser.hpp"

int main(int argc, char **argv){

  TApplication thisapplication("This Application", &argc, argv);
  
  gGuiFactory = (TGuiFactory *) gROOT->ProcessLineFast("new 
TSdaqGuiFactory();");
  new TBrowser("Browser","SMT SDAQ Browser",800,600);
  
  thisapplication.Run();
  
  return 0;
}

===================================================================
(sdaqbrowser.hpp contains the line:
	#include "smt_ped_tools/TSdaqGuiFactory.hpp" )


However, when I run the resulting binary, I get the errors shown at the 
end of this message. Can anyone see what's going wrong? The version of 
ROOT being used is v3_05_00b and I'm running in Linux with GCC 3.1.

Thank you all for any help you can send my way,

Simon
