So how did you get to this point?

Are you working from an example, or what?

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.

[HMSEdinburge]

Yes its from an example...

[HMSEdinburge]

ok i see what u mean, it is in the folder, albeit in a different path, could u advise how to point to the correct path? TQ!

Which example? how you did get it? and did you modify it?

[HMSEdinburge]

hello.. could anyone advise how to set the correct path:  .. LWIP\Middleware\Third_Party_LwIP\altcp.c?

TQ!

[mƎALLEm]

Hello,

This is a c file. You need to:

1- Ensure that this file is actually used in your project.

2- Ensure it's present physically in your drive (especially in the project folder).

3- Ensure it's added in your project i.e. in the project explorer in STM32CubeIDE (as shown in the figure you shared).

That's it.

Hello.. i have checked yes the file is there, but the path is wrong, its  in /Third_Party/LwIP/altcp.c  instead of /Third_Party/LwIP/src/core/altcp.c!  i think its something to set at file, property , C/C++ build/ Settings. Can anyone please help? TQ!

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