TMS320F28335: IQmath , #10204-D could not resolve index library "IQmath.lib" to a compatible library ?

Hello , everyone :

    My version of CCS is V10.1.1 ，the  chip is TMS320F28335 ， PC system is win 10 。

    I want to use IQmath ，but i meet some error ， 

    Q1:  if i want to use fixed-point IQ format ， should i include IQmath.lib or IQmath_fpu32.lib ?  i have  set MATH_TYPE = IQMTH  in IQmathLib.h file。

    Q2:  I think IQmath.lib should be added if  i want to use fixed-point IQ format ，but  i get some warning ," #10204-D could not resolve index library "IQmath.lib" to a compatible library "

I refer  C200Ware 3.3  IQmath  example , it use  IQmath_fpu32.lib。dir is  "C:\ti\C2000Ware\C2000Ware_3_03_00_00\libraries\math\IQmath\c28\examples"

who can give some help , thanks very much 。^_^
