I am getting a CMake error when I do 'idf.py set-target esp32'. What am I doing wrong?

The problem seems to be be scpecific to my Raspberry Pi. The same code works on an x86_64 host. (And yes, I did install the ARM host build toolchain on the Raspberry Pi.)

This problem seems to be specificly with a Raspberry Pi as the host. I *think* it might be a arch. error -- The toolchain seem to be for a different ARM Linux system than the Raspberry Pi. I am using a Pi 4:

What esp-idf version is this? Can you try updating to the master branch to see if this is still an issue?

Posted: **Sun Jun 26, 2022 8:36 pm**

I am using 4.4.1. I am not sure if the main third-party component I am using (OpenMRNIDF) will work correctly with a newer version of the IDF.

My project compiles just fine with 4.4.1 on my x86_64 Ubuntu 18.04 machine. The problem is the Rasperry Pi 4 is my workbench machine, and I would like to use it as the machine I flash my projects.

Posted: **Tue Jun 28, 2022 6:29 pm**

OK, I tried to install from the master branch, but things fail in install.sh:

After installing the newer compilers, I get this error:

Installing Python environment and packages
ERROR: This script was called from a virtual environment, can not create a virtual environment again

Which makes no sense.

I guess the answer seems to be that the esp-idf does not work with a Raspberry Pi host...

Things seem to be working fine on my Banana Pi M64 (running 64-bit (aarch64) Armbian). The problem seems to be a mis-built toolchain for 32-bit arm (bad -march options?).

OK, I finally go around to updating to the master branch. Different error:

mdns has moved to be a separate component now.

Run 'idf.py add-dependency espressif/mdns==1.0.3' in your project and then build. You'll end up with a 'dependencies.lock' file that you should add to your version control.
