What's Uni?  Oh, university?  Heh, you're not at an .edu address...

Yes, the error message refers to the math library.
"-lm" means "link with libm.a" (or libm.so, depending).
But the -lm directive seems to be misplaced somehow, 
perhaps from your host/target makefile fragment.

We're at version 6.8, though -- we can't help you too much
with version 6.2...
