../components/arduino/cores/esp32/esp32-hal-uart.c:242:19: error: implicit declaration of function 'uart_get_tx_buffer_free_size'; did you mean 'uart_get_buffered_data_len'? [-Werror=implicit-function-declaration] if (ESP_OK == uart_get_tx_buffer_free_size(uart->num, &txRingBufferAvailable)) { ^
~~~~~~~
The IDF function used in the master branch from Arduino Core Github, uart_get_tx_buffer_free_size()
, has been included recently to IDF 4.4.2.
Please update your IDF to the latest master for IDF 4.4.2 from Github and after that it will work fine.
This issue is solved in Arduino Core 2.0.5 that uses IDF 4.4.2.

Description
Compiling my project with arduino as a component fails with this error:

Debug Message
Other Steps to Reproduce
I followed the instructions in:
https://espressif-docs.readthedocs-hosted.com/projects/arduino-esp32/en/latest/esp-idf_component.html
specifically: mkdir -p components && \ cd components && \ git clone https://github.com/espressif/arduino-esp32.git arduino && \ cd arduino && \ git submodule update --init --recursive && \ cd ../.. && \ idf.py menuconfig
after configuring the arduino component I then attempted a build and got the above error
I have checked existing issues, online documentation and the Troubleshooting Guide
