I've my application that uses the stemwin (STemWin532_CM4_OS_IAR.a) with IAR compiler. Up to version 8.10 of the IAR compiler I never had any warning or error during the build of the project.

Upgrading the IAR IDE to version 8.11 I have this error:

'Warning[Lt009]: Inconsistent wchar_t size

STemWin532_CM4_OS_IAR

.a has wchar_t size 16 bits '

IAR Information Center for ARM need needs to be rebuilded the stemwin library with new version of the compiler to avoid unpredictable issues.

How I can solve this issue?

Thanks

Hello,

There is a braek of compatibility between 7.xx and 8.XX IAR versions and all the binaries generated with IAR 7.xx needs to be re-genrated with IAR 8.xx.

This is already passed along to our development team and a 

new STemWin binaries supporting IAR 8.xx will be provided with the new release of Cube firmware packages.

So, please keep an eye out for the next update of your Cube package !

With Regards,

Greetings, Imen

I was just checking in with you to see if you could provide me with an approximate date of inclusion of this fix for the STM32H7 MCU package. We have been having the same linker warning issue for some time now and would like to have it resolved or at least know when we could expect to have it resolved.

If I check on STM32CubeMX as of today [Nov 2018], the latest H7 package is dated Jan 2018 [1.2.0] and does not include it. In addition, it has been 4 months since your response above.

Thanks much for any status update.
