I hope you are using IDF 5.0 released version and not the main branch which is being called IDF 5.1 I think.
If it's just warning you can ignore for now. Some of them are because of LVGL or C++ related.

Hi, thanks a lot for your config!Now i can use this one with my project!
I've just an issue, i'm trying to use this one with the LVGL library, i finally get working the screen, but i still can't get the touch working.
Can you help me?
Thanks in advance!!!
You can check the full template project called ESP32-TUX
https://github.com/sukesh-ak/ESP32-TUX
Finally an example that works for the Makerfabs 4.3 display - thank you. They should be paying you!!

OK, have changed to testing with ESP32-TUX, compiles and links but with some warnings.
