Subject: Need help with math functions in GCC 2.2.2
Date: 24 Jul 1992 05:28:35 GMT

I can't get math functions to compile with GCC 2.2.2 running
under linux 0.96a. I installed GCC according to the instructions
and think it works since I was able to compile the kernel I'm
running right now. But I was attempting to compile some programs
of my own and couldn't get any math functions to work. For
example the simple program:

#include <math.h>

void main(void)
{
        double x;

        for(x=0; x<=100; x++)
        {
                printf("%f %f\n",x, sin(x));
        }
}

Produces an error message complaining about undefined symbol
_sin in segment main. I am compiling with the -lm flag. What is
really strange about this is that I can compile the 0.96a kernel
with this system just fine.

Any help is greatly appreciated.
