TouchGFX & Keil in CubeMX project

After generation project from CubeMX

Error: L6218E: Undefined symbol MX_FREERTOS_Init() (referred from main.o).
Error: L6218E: Undefined symbol GRAPHICS_MainTask (referred from freertos.o).


Correct

main.cpp
void MX_FREERTOS_Init(void)       ->    extern "C" void MX_FREERTOS_Init(void);

BoardConfiguration.cpp
void GRAPHICS_MainTask(void)       ->     extern "C" void GRAPHICS_MainTask(void)
