LVGL and STM32CUBEIDE Integration Issue

I am working with LVGL v9.1.1, I am simulating it correctly in the simulator. When i do all the step of integration with STM32 Project (STM32CUBEIDE v1.16.0). I am getting these errors? why this is been happening. 

Is this toolchain issue/ any bug?

Note: i have cross verify my integration process by developing gui in LVGL v8.3 and integrating it with STM32CUBEIDE, that's working fine.
