Subject: help ! undefined reference when compiling

HI !


When compiling the following program with djgpp for dos

#include<math.h>
void main (void)
{

double d , n ;
d = 40.05 ;
n = sin ( d ) ;

}

with the command: gcc -lm sin.c

I get the following error message:

sin.c(.text+0x20): undefined reference to 'sin'.

The same program compile successfully with gcc for Linux.
You note that hello.c ( in \samples\hello of djgpp dist ) compile also with 
djgpp for dos, and gcc sees math.h, and the math library libm.a is present.
thank you very much for your help.

ciao

andrea
