I'm getting the following error while running make all, and I have no Idea how to resolve this.

Hi @dr2okevin,

I am curious which ESP-IDF are you using?
I've build this firmware times ago, so I don't really remember well but if I remember correctly I used version 3.2. Could you please make sure you're using the same version? Looking at the error I think it's just a version compatibility.

Let me know.

I have just installed it with the command from the readme
git clone --recursive https://github.com/espressif/esp-idf.git
I couldn't find any version ifnormation besides this

cat toolchain_versions.mk 
SUPPORTED_TOOLCHAIN_COMMIT_DESC = esp-2021r1
SUPPORTED_TOOLCHAIN_GCC_VERSIONS = 8.4.0

CURRENT_TOOLCHAIN_COMMIT_DESC = esp-2021r1
CURRENT_TOOLCHAIN_COMMIT_DESC_SHORT = esp-2021r1
CURRENT_TOOLCHAIN_GCC_VERSION = 8.4.0

As you can see from the official ESP-IDF git repisotory (i.e. the link from which you're clonig the framework) there are different releases.

When you run git clone --recursive https://github.com/espressif/esp-idf.git and clone the repo, you're automatically using the latest stable version (i.e. master branch), that in this case - according to this - is ESP-IDF Release v4.3.1.

Probably there are some "major changes" between v3.x and v4.x - or at least, this is what that screenshot above is suggesting to me. Therefore, what you can try to do is to checkout to branch 3.x (if I remeber correctly I used v3.2, so let's try with this one) and then try again to compile (i.e. make all).

Hi, I'm facing the same error.
I've tried to use release 3.2 of the EPS-IDF but there is no install script. How did you install that version?
