Hi,

Thanks for your answer both,

ag123, you're right, the post in the wrong forum, I think the issue is more related to sloeber+eclipse which generate a wrong makefile configuration. Generation of makefile is automatic.

Hello,

Configuration : eclipse 2021-03 + GNU MCU + Sloeber + core STMicroelectronic 2.0.0

reason :
in file variant.h : #include VARIANT_H
the value of VARIANT_H seems never declared ...
