mplab c18 linker problem

[ponjo]

Hi all,
I downloaded the code of MyApp from PicOs page and I'm trying to build it with 18f5420.lkr . This is my first project for a course and it gives the following error:

Debug build of project `C:\Users\duygu\Desktop\jdfd\het.mcp' started.
Preprocessor symbol `__DEBUG' is defined.
