| RTOS example doesn't compile |

Hello all,
I have trouble compiling ex_rtos_demo_1_tasks.c from the examples directory without any modification. I am using PCH 4.064.
| Code: |
#include <18F452.h>
#use delay(clock=20000000)
#use rs232(baud=9600,xmit=PIN_C6,rcv=PIN_C7)
// this tells the compiler that the rtos functionality will be needed, that
// timer0 will be used as the timing device, and that the minor cycle for
// all tasks will be 100 miliseconds
#use rtos(timer=0,minor_cycle=100ms)
// each function that is to be an operating system task must have the #task
// preprocessor directive located above it.
// in this case, the task will run every second, its maximum time to run must
// be less than or equal to the minor cycle, and there is no need for a
// queue at this point, so no memory will be reserved.
#task(rate=1000ms,max=100ms)
// the function can be called anything that a standard function can be called
void The_first_rtos_task ( )
{
printf("1\n\r");
}
#task(rate=500ms,max=100ms)
void The_second_rtos_task ( )
{
printf("\t2!\n\r");
}
#task(rate=100ms,max=100ms)
void The_third_rtos_task ( )
{
printf("\t\t3\n\r");
}
// main is still the entry point for the program
void main ( )
{
// rtos_run begins the loop which will call the task functions above at the
// schedualed time
rtos_run ( );
} |
And all I get are these errors from the compiler:
| Code: |
Executing: "C:\Program Files\PICC\Ccsc.exe" +FH "C:\Program Files\PICC\Examples\ex_rtos_demo_1_tasks.c" +DF +LN +T +A +M +Z +Y=9 +EA

Halting build on first failure as requested.

Any idea what the problem is? |

You only get the RTOS if you have the IDE compiler (PCWH, etc.)
You don't get it with the command line compilers (PCM, PCH, etc.) |
