Installing "M5Stack-IDF" will result in errors

    Hello,

    I installed M5Stack-IDF and I got errors:

    My steps:

    1. Download and install esp-idf from https://github.com/espressif/esp-idf

    2. Check version: %
      Input: idf.py --version
      Result: ESP-IDF v4.3-dev*

    3. Install M5Stack
      Input: %git clone --recursive https://github.com/m5stack/M5Stack-IDF.git

    4. Input: %make menuconfig
      Switch on "Autostart Arduino setup and loop on boot"

    5. Compile
      Input: %make flash monitor

    6. Get errors:
      a.) /Users/<name>/esp/M5Stack-IDF/components/arduino/cores/esp32/libb64/cencode.c:

    Can anyone help me?

  • Hi @sheepDog

    I get the same errors. I am afraid that M5Stack-IDF is too old (updated 2 years ago) to work with the latest esp-idf. For one thing Espressif has since moved on to use CMake & python scrips to build instead of just make. (I am not that familiar with either, but I think they don't play well mixed together.)

    Just curious. What is it that makes you want to use the idf instead of an Arduino environment?

    Thanks
    Felix

    Hello @felmue,

    thank you for your interesting informations.

    The two main reasons why I use IDF are:

    • I am developing a large project and so I need an IDE that can handle such a project clearly. For example, it becomes quite confusing when you have more than 20 files.

    • I wanted to be very close to the examples of expressif, because in past I got some unpleasant mistakes in some libraries.

    hey @sheepDog, take a look at the following repo: M5Stack-IDF-4.0, maybe it can be of use to setup a IDF 4.0 environment as you'd like

    Hi @brus,

    thank you for providing your repro. In the meantime I've put together my own version and I'm waiting for the official version of m5stack.
