Using arduino-esp32 as ESP-IDF 4.x component in Eclipse

[Sterpa]

Dear All,
We have good instruction and additional issues (1) (2) that explaned how to use arduino-esp32 as ESP-IDF 3.x (GNU) component, include external librares and build project.
But it seems not work on ESP-IDF 4.x (CMake)...
I try to use instruction for last ESP-IDF 4.
I clone arduino-esp32 repository to "components" subdirrectory and run idf.py menuconfig (not make menuconfig)
and oops... there is no any options for Arduino, no "Autostart Arduino setup and loop on boot"!

Q1: What's wrong with idf.py menuconfig on ESP-IDF 4.x, where is Arduino option?

Next point - all of our instruction and issues based on cloning arduino-esp repository in to project subdir "components". But now Eclipse have built-in Arduino plugin, and we could add ESP32 board with just adding package_esp32_dev_index.json url in Arduino settings in Eclipse.
This will install arduino-esp32 repository to default folder C:\Users\UserName\.arduinocdt.
All external libraries will be in C:\Users\UserName\.arduinocdt\libraries
All build-in libraries will be in C:\Users\UserName\.arduinocdt\packages\esp32\hardware\esp32\1.0.4-rc1\libraries

Q2: Is it possible to use C:\Users\UserName\.arduinocdt arduino-esp32 repository in ESP-IDF project, without cloning it in to project directory?

I tryed to change COMPONENT_PATH in this #1449 issue like
COMPONENT_PATH += C:\Users\UserName\.arduinocdt but it is not worked...

Thanks a lot for ideas!

The cmake environment is not yet set up to allow arduino as a component in IDF 4.0. This will likely arrive first in https://github.com/espressif/esp32-arduino-lib-builder.
For your second question, use a filesystem that allows symbolic links. I link arduino and other libraries all the time, saving a lot of space. Compilation is also 3x faster in linux compared to Windows.

Well...
I try to use esp-idf-v3.3 + arduino-esp32(branch/idf-release/v3.3) It works well, but only in GNU make mode, and only in command prompt...
In Eclipse i got horrible errors with (failing to find all header paths).
Using esp-idf-v4 impossible, because:

1. arduino-esp32 support maximum v.3.3
2. idf-eclipse-plugin don't support esp-idf-v3.3 (no cmake setup script)
3. arduino-esp32 have no release for idf-v3.3, so, i cannot install arduino-esp32-v3.3 in eclipse with package_esp32_index.json (you only have it for v.3.2)

This is hell circle...

Do you plane to provide package_esp32_index.json for arduino-esp32-v3.3 ?

Hi Espressif.
I also would like a way to use arduino with esp-idf 4.0.
But as I understand arduino-esp32 is based on IDF 3.3 and I can't use it as a component for idf 4.0. It is then recommended to roll back the idf version to one compatible with the arduino component so 3.3.

Last arduino-esp32 release is from octobre and the gap with 3.3 is increasing...
Will there be an arduino-esp32 release soon?
