Here is my test program:

#include <stdio.h>
#include <math.h>

main () {
  double result;
  double x=2.718;

  result=log(x);
  printf("Log of %g is %.2g\n", x, result);
  return(0);
}

when I compile the program as follows:
cc test.c

I get the following error:

Undefined                       first referenced
 symbol                             in file
log                                 test.o
ld: fatal: Symbol referencing errors. No output written to a.out

The math.h file is in /usr/include. I tried compiling with -L /usr/include but it didn't work.


Thanks.
Theta.
