I'm not sure what you're doing, but I think you're trying to
be too fancy for CCS. There is no linker in CCS, so there
is no "extern". All files have to be "added" to the project
with #include statements. Here is one way to do a project
with several source modules in CCS:
| Code: | #include <18F458.H>
#fuses XT, NOPROTECT, NOBROWNOUT, NOWDT, NOLVP
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, errors)
#use i2c(Master, SDA=PIN_C4, SCL=PIN_C3)
#zero_ram
#ignore_warnings 202, 203
//----------------------------
// Header files for your modules.
#include <ds1307.h>
#include <24LC256.h>
// Other source modules.
#include <ds1307.c>
#include <24LC256.c>
//----------------------------
// Function prototypes for functions in this module.
void power_up_init(void);
//=======================================
void main()
{
power_up_init();
init_eeprom();
// Put other code here.
while(1);
}
//===========================
void power_up_init(void)
{
setup_adc_ports(NO_ANALOGS);
output_low(PIN_A0);
output_high(PIN_A1);
// etc.

| I'm trying to add a .c file to my project using the #include but the compiler tells me "File can not be opened", and no file is added to my project. I even created a new project with the code above from PCM programmer and got the same results. What am I not doing right? Me compiler version is 4.104 |

Are you using
#include "filename.c"
or
#include <filename.c>
they are different.
While the "" looks in the same directory as the 'C' file you're compiling, <> will look in the library paths (whatever they may be)
if you have a subdirectory of .C files in your project directory, then you should include that subdir like thus:
#include "somedir/somefile.c"
I've also had global routines included in sub-projects like this
#include "../globalroutines.c"
