In general, you should post the exact errors when asking a question of
this sort, since it helps people find your problem more quickly.

In this case, I suspect the problem is you need to add "-lm" to the
compile line, like

cc     out.c -lm  -o out 

The math library is not linked in by default, even if you #include
<math.h>.  So you have to add the -lm.
