Remove it from your project tree and add it again using drag and drop.

So how did you get to this point?

Are you working from an example, or what?

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

This means altcp.c is missing in this path: Middlewares/Third_Party/LwIP/src/core or may be you don't need it, so try to remove it from your project tree.
