Hi,

I been getting this warning message, which i couldn;t able to understand. The code was working fine. But when i added a single statment in the same file. It started giving me this warning message, which dosn;t compile to produce a object file

This is the main file, when i compile this i get the following warning message.

Code:
#include "include/stdint.h"
#include "include/pxa255.h"
#include "include/viperlite.h"
#include "led.h"

int main()
{
    int temp = 10;

    ledInit();
   
    // After adding this line i started getting the following warning,
    LedOff(LED_GREEN | LED_RED | LED_YELLOW);
    
    while(1)
    {
        temp = 12;
        ledToggleYellow();
        delay_ms(50);
        ledToggleGreen();
    }
    
    return 0;
}
And warning message
Code:
blink.c: In function `main':
blink.c:12: warning: implicit declaration of function `LedOff'
blink.c:17: warning: implicit declaration of function `ledToggleYellow'
blink.c:19: warning: implicit declaration of function `ledToggleGreen'
What does this message means, and when do we get these.

Thank you
