System Workbench for STM32

Dear Sir Vetch,

Thank you to come back in this post!
My board is not a eval type ST board, its custom board for my particular circuit.

Regarding stm32f0xx_ll_rcc.h file, come across in build errors, one ST expart says "This "Low Level" lib is part of CubeMX, or a sub-set thereof, and are labelled with this "_ll_" part in their name.
However, in some cases (especially for the STM32F7 I checked), this Low Level lib is nothing but a sorry stub (i.e. unusable fragments)."

I heard from other forum, Right-click on the project >> Properties >> C/C++ Build >> Settings >> Tool Settings tab >> MCU GCC Compiler >> Includes need just adding path by '....' take a look my include path setting.(attached)

"Please, un-tick the properties>C/C++ build>setting>preprocessor>Preprocess only(-E). It prevents a full compilation and link."
It makes more errors.

Hope you will help me.

Regards
Hasan
