I use in my application the stemwin (STemWin540_CM4_OS_IAR.a) with IAR compiler. Up to version 7.8 of the IAR compiler I never had any warning or error during the build of the project.
Upgrading the IAR IDE to version 8.20 I have this error:
"Warning[Lt009]: Inconsistent wchar_t size
STemWin540_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?
