Hi...
I'm in urgent need.. i got this program somewher from the net and i've edited it for my line follower which i'm building....but the program shows some errors(the microcontroller used is atmega16) and i'm totally confused about the header files 'delay.h' and 'mega16.h' i tried using the header files provided in the avr_libc..but it shows several errors.... can anyone help me resolving this problem...
how can i create an errorless program....
pls help me..... i dono much about microcontrollers....
thank you...

Could you post the error list as well?
dep/delay.h:1: *** missing separator. Stop.
Build failed with 1 errors and 0 warnings...

i'm using avr studio 4......

i'm not so good at c programming so i donno much abt debugging....
this delay file. i got from the avr_libc....

That looks like a makefile error. If you made your own makefile, be sure that it uses tabs instead of spaces for indentations. If not, then try making your own makefile (there are dozens of tutorials out there) and see if it works correctly.

ok sir but is the program correct....

even if i correct the above error i'm getting several other errors.....(about 25errors)
i think all this is due to only linking of other files which is not done properly..and tats wat i donno.....

Added after 11 minutes:

This is the make file for the program..
