There is a seperate library for the functions in <math.h>; link with -lm

1. Trouble finding C's math functions: log10(), sin, etc...
Do you know where I can get the C runtime library math functions?
I'm writing a C program and I want to call log10(). When I compile,
the error I get is "... undefined symbol _log10()..."
Using: SLS 1.0
Kernel: 1.55
GCC: Version 2.5.8
LibC: Versions 4.5.pl25 (I think)
Any help appreciated.
