   Here we go again!  I get this message:

   GNU C++ Compile: SINE.c -lpc
   SINE.c(.text+0x32): undefined reference to `sin'

   ... when I compile this program:

   #include <math.h>
   #include <stdio.h>
   main ()
   {
   float d = 40.05;
   float n ;
   n = sin( d ) ;
   printf("The sine of %f is %f", d, n);
   return(0);
   }

   ...I even tried using -lmath in the command line.
   Why Oh why does this happen?  Doesn't
   "#include <math.h>" define a reference to 'sin'?
   TC Lite handles it just fine.
   Thanks again for the help.
