Warnings linking example with IAR Embedded Workbench

Question

Hello 

I'm trying to evalute Embedded Wizard Studio and have the following problem

When linking the example code for STM32F746-Discovery with IAR Embedded Studio 8.30.1I get 

Warning[Lt009]: Inconsistent wchar_t size 
            ewrect.o(libewrte-m7-iar.a) and 17 other objects in 9 different libraries have wchar_t size 16 bits 
            Application.o and 82 other objects, some of them in m7M_tls.a and 30 other libraries have wchar_t size 32 bits 

According to 

https://www.iar.com/support/tech-notes/general/library-built-with-7.xx--causes-warning-message-in-8.11/

This could be the problem. Which version of compiler did you use?

best regard

Answer 1

Hello Hakan,

the libraries for IAR are created with IAR C/C++ Compiler for ARM 7.80.4.12462.

Due to the fact that we are not using wchar_t within Graphics Engine or Runtime Environment, there should be no problem if you are using a higher version of IAR (according to the referred technical note from IAR).

Best regards,

Manfred.
