I think that the message from gcc is clear enough:

C:\D\OUTPUT>gcc -g3 -O3 xx.cc -lgpp -lstdcxx -o xx
xx.cc: In function `int main(...)':
xx.cc:6: warning: cannot pass objects of type `String' through `...'

That means that You should add explicit cast to 'const char *' as
object of class String cannot be used as parameter to printf:

   printf("|%s|",(const char *) test);

After that the example works (One hint: if you get unresolved 
references without optimizations try -O)
