gcc compile problem ...

[Brian J. Dent]

gcc help,

Obviously I am new to the GNU gcc compiler.

I've been trying compile a program on our SUN with gcc 
(sparc-sun-solaris2.7/2.95.1) and it contains some intrinsic 
functions.  When I get to the point of linking it doesn't recognize the 
functions, eg:  sqrt.  Below is a test program.  What is missing that I am 
not finding the built-in functions to link with?  Thanks for any help.

file:marc.c:
#include <stdio.h>
#include <math.h>

main()
{
         double x = 2;
         printf("sqrt of %d is %f\n",x,sqrt(x));
}

gcc -c marc.c
gcc -o marc.out marc.o
Undefined                       first referenced
  symbol                             in file
sqrt                                marc.o
ld: fatal: Symbol referencing errors. No output written to marc.out
collect2: ld returned 1 exit status
