How Wise Studio work????

[SBaro.11]

Hi all, 

I'trying to explore steval board with BlueNRG2 chip, I'm working on BLE_SensorDemo project, works nice, right now I wan to develop my owm file, so far I've developped a library for SPI flash.

I've added my header in Inc folder et my source file in Src folder, so I can include my header but if I try to call my init function flash_init() declare in my header I got a fuc**** undefined reference to flash_init I really don't understand why wise studio is really really strange

 

Why stm don't use STMCubeIde ? 

[Techn]

Did you include this header in your main.c?
