I'm using MPLAB IDE V7.20 when I include "lcd.c"

it generate error during make:

:(

anyway I used HDPIC IDE to make it, it's ok..... but still there is no output on the LCD..... :(

Thanks
 

ok now I get to work...

code:
Code: 
void main()
{
	TRISA = 0xF3;
	TRISB = 0xF0;
	DelayMs(100);
	lcd_init();
	lcd_clear();
	lcd_puts("I'm the man!");
	//lcd_putch('T');
}

Thanks :)

Thanks
