I am getting a make file error when building the project.Can you please help me to resolve this?

arm-none-eabi-u_printf_float is wrong.

The compiler is arm-none-eabi-gcc

-u _printf_float is a linker option for enabling floating point io. It is repeated correctly later in the command line.

In STM32CubeIDE there should be no need adding that option manually. It can be enabled in the IDE Project > Properties > Settings MCU Settings by checking "use float with ...".

Another (?) common source of trouble is the space in the project name "E:\SANAVA_PROJECTS\Vibration Sensor\...". This is problematic when Windows and GNU tools meet. Avoid any special characters in your project path, keep it short and plain ASCII letters, numbers and underscores.

Thank you for your valuable response.I have changed the compiler to arm-none-eabi-gcc .

But it is showing not found arm-none-eabi-gcc .

Can you please help

Can you please help me to build this project successfully

Hi @AE.2​ ,

there may be some issue in your .ioc creation of the default project of the STWINKT1.

Can you start your project from an already existing example, and add to this your user code? For instance, you can choose the Serial_DataLog SW4STM32 project you can find in \Projects\Serial_DataLog\SW4STM32\STWIN_DATALOG.
