sorry, mistake of me, I forgot to compile lua-binding and local_path

Hello
I actually want to add Lua to my C++ project . And I did All the steps I could and it ended up having the same problem as you. Seems like you’ve been successful to run the project but I really do not understand what exactly you did to run the project. What do you mean by forgetting to compile lua_bindings ??? How did you compile it ?

look at the project lua tests and copy their project settings in the android.mk file
