Tool/software: TI-RTOS

I m trying to use TIRTOS in my project with TM$C1294NCPDT. I am using the evaluation board and try to implement mailbox. However when I include Mailbox_post(mbx, &msg, TIMEOUT); in my code it throws a linker error - Description Resource Path Location Type
Undefined reference to 'ti_sysbios_knl_Mailbox_post__E' in file ./ethcmd.obj .xdchelp /udpecho1 C/C++ Problem.

Could you help what is the problem

When you start using a TI-RTOS kernel module, there are two things you need to do

1. Add the header file in the file that is using the module
#include <ti/sysbios/knl/Mailbox.h>

2. Add the module into the .cfg file (and configure the module as desire if you don't like the defaults).
var Mailbox = xdc.useModule('ti.sysbios.knl.Mailbox');

I expect you don't have #2.
