Line Follower Help

[mirrayhan08]

hello every body,
I need help on my line follower robot based on PIC 16f877A. i download C source code and try to compile this code in MPLAB. but it show missing error in first 6 line. but i can't find any problem those line. i give the code without header file. plz any body find the error or convert it HEX format.

It is very very emargency in my study.

Plz help me very queckly.

Thanks to all

Mehedi.
