Hi

Not quite understanding what you are doing, but normally an undefined 
reference symbol means that the compiler in the linking stage doesn't 
know the appropriate "external" library to link to because it hasn't 
been explicitly referenced in the compiler command. This seems to be  a 
feature of newer binutils, where in older version you could get away 
with it because it was referenced from another library
