WTA MPLAB compiler problem

[alpha91]

Hi, i am new to PIC microcontroller programming.
i just installed the MPLAB, when i testing with the code online which i think is error free, it failed to build. it comes out the message below:

Build C:\Users\Fei\Desktop\Final Year Project\PIC code\test\test1 for device 16F877A
Using driver C:\Program Files (x86)\HI-TECH Software\PICC\9.70\bin\picc.exe

********** Build failed! **********

the PIC i am using is 16f877a and the code is below:

#include <htc.h>
#define _XTAL_FREQ 8000000
void main()
{
TRISB=0X00;
PORTB=0X00;
while(1)
{
PORTB=0XFF;
_delay_ms(100);
PORTB=0X00;
_delay_ms(100);
}
}

can i know what's the problem? and also i am using HiTech Universal Toolsuite, if i want to write the program in assembly language, is it ok with this toolsuite ?
