Environment

Problem Description

1.I have installed and run esi-idf-v4.3, and tried "Blink" example. Since I want to use esp-adf, and I found that esp-adf wad based on esp-idf, but esp-adf nowadays was not supported by esp-idf-v4.3, so I downloaded and want to install esp-idf-v4.1. Python 3 and pip were all past testing by esp-idf-v4.3, while, esp-idf-v4.1 couldn't be installed on the same machine run esp-idf-v4.3 well. 2.when I run xtensa-esp32-elf-gcc --version, it was prompted:"xtensa-esp32-elf-gcc: command not found"

Expected Behavior

When I typed "esp-idf.py menuconfig", it would shown the config menu.

Actual Behavior

1.https://ibb.co/NxvpZ1x 2.https://ibb.co/vw0ws0p

Steps to reproduce

  1. Download and unzip esp-idf-v4.1
  2. ./install.sh

Hi @mianqi2016 Please use the latest release: v4.1.2. It will prefer the use of python3. And make sure that you have installed the packages from https://docs.espressif.com/projects/esp-idf/en/release-v4.1/get-started/linux-setup.html#install-prerequisites.

If you cannot switch to v4.1.2 then installing the python-pip-whl (https://packages.ubuntu.com/focal/python-pip-whl) package could be a workaround. I don't recommend this solution.

BTW, the master branch of ESP-ADF seems to be based on ESP-IDF v3.3 and not v4.1 as you think. cc @jason-mao

I'm sure after several days trying in different time, I have downloaded esp-idf-v3.3.5 rightly just now, but when I run "./install.sh", it was said: `Installing ESP-IDF tools

I am sure I have pip installed since I have installed esp-idf-v4.3.

mianqi2016 commented 3 years ago

When I typed:pip --version It was shown: pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8) while, in the upper comment, it was said:/usr/bin/python: No module named pip Should I add pip here - /usr/bin/python, or I need to change the directory from "/usr/bin/python" to "/usr/lib/python3/dist-packages/"?

dobairoland commented 3 years ago

v4.3 used Python 3 for which you have pip. When you switch to older releases then Python 2 is used by default for which you don't have pip.

You can install pip for your old python manually:

wget https://bootstrap.pypa.io/pip/2.7/get-pip.py          # you can download this with any tool you prefer
/usr/bin/python get-pip.py --user        # --user ensures that it will be installed in you home directory (no sudo is required)

There is also a possibility to install the python-is-python3 package which will make python be linked to python3. This setting might affect other software in your computer since it will be set for everything. But it is better to use Python 3 because Python 2.7 is no longer supported (by the Python developers) and some packages could be incompatible.

Right, I went to ". ./export.sh", but there was still errors, I'm seeking for solution. Thanks!

dobairoland commented 3 years ago

Yes, that update-alternative does the same as installing python-is-python3. It will link "python" to "python3".

What have you tried @mianqi2016? Export have reported the same error as before?

mianqi2016 commented 3 years ago

This was the error prompt:https://ibb.co/5jZrxZz I found the key words were: "IDF_PYTHON_ENV_PATH: (not set)", I found the solution was:

  1. add "export IDF_PATH=~/esp/esp-idf-v3.3.5" into "~/.profile"
  2. comment current "export IDF_PATH=~/esp/esp-idf-v4.3"
  3. Restart. Then, it was OK - https://ibb.co/1Twj3bk

Why there was a erase line on my first step description？I haven't mark it.

mianqi2016 commented 3 years ago

The newest error:"ImportError: No module named click" after I typed "idf.py menuconfig".

mianqi2016 commented 3 years ago

I found it searched tools under v4.3 directory, while, I want it in v3.3.5 directory(https://ibb.co/Ht4MQDT), that means I want command "idf.py" point to "esp-idf-v3.3.5" other than "esp-idf-v4.3", how to do it?

dobairoland commented 3 years ago

@mianqi2016 Please check the content of $IDF_PATH before running export.


echo $IDF_PATH      # set it to the right version of ESP-IDF if it is incorrect
. $IDF_PATH/export.sh    # don't forget the dot in beginning
mianqi2016 commented 3 years ago

I went to "make menuconfig" in "esp-adf", I used esp-idf-v3.3.5, and could run "make flash", while, it was said: "cc1: some warnings being treated as errors"

  1. https://ibb.co/NrPhBHk
  2. https://ibb.co/rZHRB1S
  3. https://ibb.co/j6G8tN6

I tried the 2 examples in "get-started" - "play_mp3" and "play_mp3_control", both the same, Are these errors of source code or of compiler?

dobairoland commented 3 years ago

@mianqi2016 Please report ESP-ADF related issues in https://github.com/espressif/esp-adf/issues. You will get better help there. The build issue you linked appears in the ESP-ADF project.
