Lpc2000

Hi,
Wondering if anyone can shed some light on this...
using Keil and the GNU compiler for LPC2114.

I have a function that it to output a value to the terminal and 
converts it to a decimal in ASCII Characters, and the length of this 
can be determined by the function call.

Anyway, the following compile error results:
"
.\flash\terminal_fncs.o(.text+0xe38): In function `Print_DEC':
: undefined reference to `__udivsi3'
.\flash\terminal_fncs.o(.text+0xe6c): In function `Print_DEC':
: undefined reference to `__umodsi3'
collect2: ld returned 1 exit status
Target not created
"

I have commented out line by line and found 3 culprit lines they are 
marked with comments indicating they are a problem,. and the entire 
function can be seen here:

void Print_DEC(unsigned int value,unsigned int order)
{
unsigned char trailing_spaces;	// how many spaces to pad at end 
unsigned char digit_flag;	// set when first digit is hit
unsigned char calculate_value;

trailing_spaces = 0;
digit_flag = FALSE;

while (order > 0)
	{	
	// must show last digit if it is zero 
	if (order == 1)	
	   {
	   digit_flag = TRUE;
	   }
	// determine if digit is present 
	if (value >= order)
	 {
	 calculate_value= (value / order)+48;
	 Term_Tx(calculate_value);	 //WHY DOES THIS NOT WORK????
	 digit_flag = TRUE;
	 }
	else 
	 {
	 // no leading zeros, only in body of number 
	 if (digit_flag)
	   {
	   Term_Tx('0');
	   }
	else
	   {
	   trailing_spaces++;
	   }
	}
	
	value %= order;		 //WHY DO THIS NOT WORK?????
	order /= 10; 		 //WHY DO THIS NOT WORK?????
	}

// now pad spaces to overwrite previous number which may have had 
more digits 
while (trailing_spaces > 0)
	{
	Term_Tx(' ');
	trailing_spaces--;				
	}
}

the function Term_TX simply transmits an unsigned char to the com 
port.

Any ideas what these compiler errors mean, and what is causing the 
problem????

Thanks in advance

kind regards

You are either missing a library in your link command or your processor 
library is missing some support functions (specifically unsigned 
division).  Probably the former.
