[STemWin]Inconsistent wchar_t size warning on IAR 8.50.1

[Tiel]

Hello,

When I try to build source codes including STemWin(5.40) library, following warning is shown and display is not work. when I tested at IAR 7.80.4, there was no problem.

Warning[Lt009]: Inconsistent wchar_t size 

      GUIAA_Char4Ext_XBF.o(STemWin540_CM4_IAR.a) and 166 other objects in STemWin540_CM4_IAR.a have wchar_t size 16 bits 

      __proc.o and 310 other objects, some of them in dl7M_tlf.a and 99 other libraries have wchar_t size 32 bits 

When I searched iar warning info, I found this

In EWARM version 7.80 and earlier, the size of wchar_t was 2 bytes wide and the runtime attribute was set accordingly.

In EWARM version 8.11 wchar_t is 4 bytes wide and the runtime attribute is set accordingly.

As a result, we need to differentiate emWin Library by IAR version.

Could any one know where to find STemWin library to be able to support IAR 8.x?

Best Regards,

Tommy Lim

Hello @Tiel​ and welcome to the Community 🙂

Could you precise which package firmware are you using?

Today, STemWin-library based on version V5.44 on the STM32Cube MCU package:

/Repository/STM32Cube_FW_XX_Version/Middlewares/ST/STemWin/

You should follow the configuration steps provided in the AN4323: Getting started with STemWin Library, in section “3 How to use STemWin Library step by step�?.

Hope this helpful for you.
