Undefined References for GateTask

When exploring the implementation of the GateTasks, both embedXcode and Energia raise errors about undefined references.

Here's the code for Energia:

#include <Energia.h>
#include <xdc/runtime/Error.h>
#include <ti/sysbios/gates/GateTask.h>
#include <ti/sysbios/BIOS.h>

    GateTask_Handle GateTaskHandle;
    IArg GateTask_key;

void begin()
{
    Error_Block eb;
    Error_init(&eb);

    GateTask_Params params;
    GateTask_Params_init(&params);
    GateTaskHandle = GateTask_create(&params, &eb);
}

void enter()
{
    GateTask_key = GateTask_enter(GateTaskHandle);
}

void leave()
{
    GateTask_leave(GateTaskHandle, GateTask_key);
}

void setup()
{
  // put your setup code here, to run once:
  begin();
}

void loop()
{
  // put your main code here, to run repeatedly:
  enter();
  leave();
}
