I cannot find MX_LWIP_Process() defined in my lwip.c. Why and how should I do?

I am trying to use LwIP with FreeRTOS.

I turned ETH, LwIP, FreeRTOS enabled in the IDE.

After generating code, I found that LwIP.c does not have MX_LWIP_Process() defined.

There is a header definition in LwIP.h, but no function declaration in LwIP.c.

Why does this happen? In this case, what should I do to use MX_LWIP_Process() in for loop.

I found the reason by myself.

With FreeRTOS ON, the MX_LWIP_Process() is not defined.

With FreeRTOS OFF, the MX_LWIP_Process() is defined.
