Hi Matt,
In case your programs use some Fortran functions from CERNLIB, you should
specify the option "-lnsl" in your link procedure.
Note that with ROOT version 3.01, you do not need to initialize ROOT anymore.
You can simplify your main program to:
//-----------------------------------------
#include <iostream>
#include <TRandom.h>
int main() {
TRandom rdm;
cout << "using a root random number " << rdm.Gaus(1,1) << endl;
}
