salvo rtos for pic16f1938

[kppp]

hello all,
I have downloaded the salvo lite version from pumpkininc website.
I am new to this RTOS. i am using their sample code and added the required files.
but i am getting the following error in main.c

Error [500] ; 0. undefined symbols:
_OSInit(rtos.obj) _OSSched(rtos.obj)

and my main.c code is as follows:

#include <salvo.h>

void OSInit(void);
void OSSched(void);

int main(void){
OSInit();

for(;;){
OSSched();
}
}

why i am getting this error? I have included the files required for this.
please guide me.
thanks and regards
