Hi, I was trying to compile the example program under esp-idf/examples/mesh/internal_communication/

But if I try to compile, I receive the following error:

Code: [Select all] [Expand/Collapse]

Hi sandhan，
First, can you compile the example examples/wifi/scan successfully?
Make sure your submodule is clean and updated. git submodule update --init and git status.

Please provide more information about your environment. Thanks.
