"unresolved symbols remain" in C2000 Piccolo LaunchPad examples

Other Parts Discussed in Thread: CONTROLSUITE

I am new to C2000 Piccolo Launchpad and I imported some examples from ControlSUITE to CCSv5, all reporting errors of "unresolved symbols remain" while linking:

>> Compilation failure
symbol in file 
--------- ---------------- 
_CLK_disableAdcClock ./Example_2802xGpioToggle.obj
_CLK_enableAdcClock ./Example_2802xGpioToggle.obj
_CLK_init ./Example_2802xGpioToggle.obj
_CLK_setOscSrc ./Example_2802xGpioToggle.obj
_CPU_clearIntFlags ./Example_2802xGpioToggle.obj

......

I do not know what to do, for these symbols can be easy found in lib but the linker says NOT...

    Hi Larry,

    I would like you to go through this doc first: 3173.Basics C2000 Launchpad.pdf

    This would solve all your queries.

    Regards,

    Gautam

    Well, I've tried the same code and followed its instructions step by step, the situation changes little:
