Does anyone have an idea what's causing this problem? Math.h does include the function prototypes for the pow function. You do not provide enough information. Is it complaining about math.h, or your use of the pow function in your program, of is it a linker message where it is saying that you have an unidentified reference. When you compile, you need to use the -lm command line flag, which causes the math library (eg. libm.so) to be included by the linker. Gerald A. Feldman <gaf at corsof.com> home:gaf at mediaone.net
