TMS320F280025: warning #10204-D: could not resolve index library "IQmath.lib" to a compatible library

Hi,

Can you try changing the link order to IQMath.lib first and then libc.a second?

Thank you very much for suggesting a solution. I think that IQmath.Lib is already up in the list above libc.a. Kindly explain further for my clarification.

I see that it is not the first entry. Can you make it the first lib? 
By that I mean,

IQmath.lib

libc.a

$(COM_TI_C200ware...)

I have tried by making the IQmath.lib the first item but the results remain the same. However if I replace the IQmath.lib with the IQmath_fpu32.lib, then the project compiles and links successfully. In the "IQmathLib.h" header file I have defined : define   MATH_TYPE      IQ_MATH. I have done some calculations verifications and the results are correct. Can anyone give a feedback if it is the optimized way of implementing fixed point calculations?. Is there any performance compromise if I use IQmath_fpu32 library in place of of IQmath library (I understand that IQmath_fpu32 is more suitable for controllers having fpu hardware. Correct me if I am wrong). The snapshot of the linker settings that work are shown in the below snapshot:

Hi,

The IQmath.lib is an index library which automatically picks out the correct library based on the project configuration. So functionally, it is exactly the same as you directly including IQmath_fpu32.lib.

To resolve the index library issue, can you try the included examples which use the IQMath index library and see if that works?
