Well, you forgot to link your math library.

You should be using `cc name.c -lm' if an executable image is that what you
want. If not, you should be using `cc -c name.c'.

The `-lxx' tells cc to tell the ld command to link `xx' to the executable image
aswell. The `-c' option tells cc to compile only (ie don't generate an
executable image).

Hope this helps,
