FP-CLD-AWS1 v3.0.1 compile error in higher STM32CubeIDE version than 1.8.0.

[ELee.16.65]

FP-CLD-AWS1 software package v3.0.1 for STWINKT1B fails to be compiled in higher STM32CubeIDE version than 1.8.0. Library link error happens. It is successfully compiled only in 1.8.0. version. It seems to be IDE bug. 

I hope it to be checked and fixed.

Exactly what errors are you getting?

The IDE changed compiler versions somewhere in the 1.8/1.9/1.10 releases, I don't recall exactly which one. And the newer compiler versions change some default compiler/linker settings. One that got a lot of attention on this forum was the change to how the linker handled "multiple definitions" of variables. Lots of sloppy code would put "int somevar" in the include file instead of "extern int somevar". With the old default "-fcommon" setting, the linker would merge all of those into a single instance. The newer default "-fno-common" does not merge them and you get dozens/hindreds of "multiple definition" errors from the linker.

Can you tell me how to change linker or compiler default setting in CubeIDE?
