Hello,

Which device is using ?

You'll probably want to review LwIP examples as you can find available in the Cube firmware package dedicated for your board.

You can also, use the STM32CubeMx tool to generate initialization code. This allow you to choose the microcontroller, select the peripherals you want and map them to pins graphically. 

Kind Regards,

Hello,

The "Undefined symbol" error means that your application does not include object, source or libraries including this function. You should review the configuration of your project, and the files included and make sure that your project contains all the required library source files.

Kind Regards,
