Hi.
I am trying to create a development environment using esp32 and lvgl.
So, I installed ESP-IDF V4.3.1.
And I tested the hello-world example of get-started.
It was confirmed that esp-idf works well.
I installed lvgl V7.7.1 in esp-idf/components/lvgl referring to Espressif (ESP32) — LVGL documentation.
And after that, the hello-world example is not compiled.
Below is part of the error message.

I tested lv_port_esp32 because it didn’t work out the above method.
D:/espressif/esp-idf <— V4.3.1
D:/espressif/lv_port_esp32
I placed the code as above.
I modified the following items using menuconfig.
Component config → LVGL TFT Display controller → Select predefined display configuration → TTGO T-display
The following error occurs.

How can I use lvgl for esp-idf ???
What is the best way to use lvgl for esp-idf ???
