When I try to build the demonstration project in C:\.....\STM32Cube_FW_F4_V1.16.0\Projects\STM32469I_EVAL\Demonstrations\EWARM,  the build error is appeared on the IAR EWARM v8.11.

The build error message is : Error[Li005]: no definition for '__iar_Sin' [referenced from pdm_filter.o(libPDMFilter_CM4_IAR.a)] 

How can I solve this problem?

Thanks.

Hi

Seo.Seonghwal

,

I tested successfullythe Demo using

IAR version 7.70 andSTM32Cube_FW_F4_V1.0.

Try to test with an old

IAR version (7.xx) this may resolve your problem.

This also applies to any example project that uses precompiled libraries e.g. like STemWin because IAR changed its wchar_t size from 2 bytes to 4 bytes since IAR EWARM version 8.1x without any option to define the size in the project. Because of this one will get a lot of warnings because of different wchar_t sizes in object files.

Hello,

I had the same issue and this workaround worked for me:

Go to 'Project' > 'Options' > 'Linker' > 'Extra options', check 'Use command line options' and add this to the command line options:

--redirect __iar_Sin=sin�?

This should basically replace __iar_Sin with sin function from standard library. But I don't know what exactly __iar_Sin is and why it was probably removed in new version of the IAR.

Best regards,
