[avr-gcc-list] Error with long type in avr-gcc

[Paulo da Silva]

Hi all

 

I am with the following problem, when I try to compile my project I have the warnning listed below, the compiler says that I have an integer overflow but I am using long type. I print the value and it is wrong.

 

void

test()

{

unsigned long tt;

 

 

tt = 1023 * 100;
printf("temp = [%ld]\n",tt);

 

}

Compiler warnning:

../a2d_read.c:39: warning: integer overflow in _expression_

 

I am using:

IDE is AvrStudio4

avr-gcc-3.4.3

MCU is Atmega8

 

 

Please tell me what I am doing wrong.
