math.h

[Bert]

Hi, here is a newbie's question:
i want RTEMS to do some simple calculations,
so there are functions like "sin(x)" and
"cos(x)" in the codes.
but when i compile the codes, it tells me
that "undefined reference to sin" and
"undefined reference to cos" ...
i have added "#include <math.h>" to the
source code, what else should i do?
