Compiling multiple source files
PostPosted: Tue Apr 03, 2012 11:34 pm     Reply with quote
I need to split my source code in to pieces in order to maintain the simplicity but when compiling it gives number of errors.

Please somebody help me.
Code:

// main source file

#define Signal_level1   1
#define Signal_level2   2
#define Signal_level3   3
#define Signal_level4   4
#define Signal_level5   5
#define Hammer_icon     6
#define Clock_icon      7

#define RTC_SCLK PIN_A0

Some header files can only be loaded once in your project, for example the CCS PIC header files.
In your gps_main.h you do an include of 16F887.h and I suspect gps_main.h is included from all your C files? There it goes wrong because then the PIC header file will be loaded multiple times causing the error message for 'Can not change device type'.

The solution is to move the include of 16F887.h to the top of your main() C-file.

Another problem is that the file Clock_functions.c is using RTC functions but is included _before_ ds1302.c. Change the sequence of these two file includings.

Would the classical IFNDEF block fix that problem for him? I've not really had any good success with multiple file units on anything complex, so I just typically #include all my .c files at the end, but if he took his fuses and call to 16F887.h and put them in a header file like this:

device.h
Code:

#ifndef DEVICE_H
#define DEVICE_H

#include "16F887.h"

//Fuses here

#endif


would something like that work for him to avoid multiple #device calls interfering?
