Building error

Hello, thank you for sharing. After downloading and compiling, I encountered the following error. How can I solve it?

Hi @zkwei6666

game_2048 is not available and result in linking issues. Have you checked out the submodules properly? If so, can you do it again please? I guess the folder for game_2048 is empty.

[zkwei6666]

Thank you ! Now it has become a duplicate definition again. Is there any incorrect configuration? thanks！

Hi,
can you please remove the complete directory and fetch the submodules again? Please make sure that there is no other game_2048 directory. The configuration of the project is working and should work without any additional steps if you have followed our instructions.

Missing git submodule update --init --recursive I think from the beginning.
