System Workbench for STM32

Hello!

Thanks for your reply. Now, any idea of the problem I was mentioning:
When I make a Cube project and import it, I usually end up with this message at compile time:

Drivers/STM32F4xx_HAL_Driver/stm32f4xx_hal.d:1: *** target pattern contains no `%'. Stop.

I tried to search the web, but couldn't find any explanation in the right context (i.e. STM32).
And for the other explanations, well, I don't get it. I'm quite new to STM32.

Best regards,

Pascal
