Thank You.

I have make sure that Project>Buile Options>Project there is C:\MCC18\lib in the library path. But I do not know why the MPLAB cannot find the header.

Try using MPLAP 7.2 or 7.22 i dont think 7.4 is supported...

The headers come from Project>Build Options>Project then the Include file path should be c:\mcc18\h

He or she is not using FIRST equipment, so don't have to worry about the versions.

Make sure you include the header files in the header section of yourproject.mcp
If that doesn't work, try putting the header files in the same folder as your project.
Usually, I just need to have #include "p18f4520.h" at the beginning of the main.c file and it works just fine. I have used the the 18F4520 on one project without any difficulty using MPLAB 7.30 and C18 v2.40.
I would need more information about what you are trying to do to suggest anything else.
