BUILD FAILED

I have created a simple project where 2 LEDs will be on. I have added the header file, "P16F628A.INC" into the header files folder in the LED.mcw. What is the problem here? It stated there that i did not define those.

You have selected relocatable or added a linker script. I suggest you start with absolute code. Start a new project and choose absolute when asked, then add the following,

		#include "p16f628A.inc" 

		__config _INTRC_OSC_NOCLKOUT & _PWRTE_ON & _BODEN_ON & _MCLRE_ON & _WDT_OFF & _CP_OFF 


		org	0x0000 

		bsf	STATUS,5  
		movlw	00h    
		movwf	TRISA
		bcf	STATUS,5 
		movlw	b'00000101'
		movwf	PORTA

stop		goto	stop

		end

__config _INTRC_OSC_NOCLKOUT & _PWRTE_ON & _BODEN_ON & _MCLRE_ON & _WDT_OFF & _CP_OFF

it is so complicated.What are those for?

Cant i do something like import the modules eg. #include "p16f628A.inc" and continue with my codes as usual? As when the header file is imported, using the declared/defined keywords should be fine.

Those are the fuses. You need to set them before burning the pic. In this case the pic will use the internal oscillator, and you need to connect master clear to vcc.

What I usually do is to define my settings once and then copy and paste it to each new project I do.

                      movlw	0x07              ; I think these should also be added

My first Flashing LED never worked until I figured you need to add those 2 lines

Owh, it worked. thanks a lot. But i dont understand why and what the code does.

Have a read of this page. It's very good.
