| Complier error with #include |

I am trying to use #include to make routines reusable and am having a complier error. My experience with compliers is that the pre-processor resolves all of the #xxx commands before handing the text to the complier. The CCS output seems to imply the included c files are complied seperately. This seems weird, the failing line is the struct declaration and the #device is in the initial included h file. Any info? The manual is rather cryptic and a simple test case I wrote does not have the problem. Compiler is Ver 3.212.
The main code is:
| Code: | #include <16F88.h>
#device *=16
#fuses NOWDT, NOPROTECT, NOLVP, HS
#use delay(clock=20000000)
#use rs232(baud=9600, XMIT=PIN_B5, RCV=PIN_B2, PARITY=N, BITS=8, STREAM=COMM_1)
#define MAX 5
Int16 Registry_Map[MAX];
Int8 REG_Map[MAX * 2];
#locate REG_Map = Registry_Map
#include "modbus.c"
void main(){
int i;
for(i=0; i<MAX*2; i++)
REG_Map[i] = 0;
while(1) {
delay_ms(10);
COMM1_Service();
}
}

The included modbus.c file is long so I am showing the first 25 lines or so. The problem is with the struct declaration:
| Code: |
// MODBUS exception codes
#define Illegal_Function 1
#define Illegal_Data_Address 2
#define Illegal_Data_Value 3
#define Slave_Device_Failure 4
#define Acknowledge 5
#define slave_device_Busy 6
#define Negative_Acknoledge 7
#define Memory_Parity_Error 8
struct Comm_Port // <==== LINE 16 PROBLEM LINE
{ Int1 Respond; //respond to command
Int1 Initialized; //initialized
Int1 Packet; //packet ready for processing
Int8 Network_Address; //address of slave
Int8 CRClo_Index;
Int8 CRChi_Index;
Int8 Index; //ptr into buffer
Int8 Start; //starting register number
Int8 Finish; //last register number
Int8 Quantity; //number of registers
Int8 Buffer[MAX*2 + 5]; //data buffer, + 5 bytes for packet overhead
//slave addr, cmd, # data bytes, CRC Lo, CRC Hi
};
struct Comm_Port COMM1;

The complier output is:
| Code: | Executing: "C:\Program files\Picc\CCSC.exe" "WaterMonitor.c" +FM +DF +LN +T -A +M +Z +Y=9 +EA
Memory usage: ROM=14% RAM=15% - 16%
0 Errors, 4 Warnings.
Executing: "C:\Program files\Picc\CCSC.exe" "modbus.c" +FM +DF +LN +T -A +M +Z +Y=9 +EA

In the Project window in MPLAB, you probably have both your main C
source file and the modbus.c file. Remove modbus.c from the list.
Then it should compile without the #device error.
If you want to see modbus.c listed in the Project Window, then
add it to the "Other Files" section.
I tested this with MPLAB vs. 7.10. |

you definitely have both your main C
source file and the modbus.c file  |

You nailed it. I had modbus.c listed as a C file. I removed and no more errors. Thanks.
