I get a new computer with macOS Catalina. Now I want't to install the developer environment. I use the following commands:

- sudo easy_install pip

- download : https://dl.espressif.com/dl/xtensa-esp32-elf-osx-1.22.0-80-g6c4433a-5.2.0.tar.gz

- mkdir -p ~/esp

- cd ~/esp

- tar -xzf ~/Downloads/xtensa-esp32-elf-osx-1.22.0-80-g6c4433a-5.2.0.tar.gz

- add this: “export PATH=$HOME/esp/xtensa-esp32-elf/bin:$PATH” to ~/.profile without quotes ””

Git clone the OVMS ESP IDF repository:

- git clone https://github.com/openvehicles/esp-idf.git

- cd esp-idf

- git submodule update --init –recursive

-add this: “export IDF_PATH=~/esp/esp-idf” to ~/.profile without quotes ””

Git clone the OVMS v3 repository and init the build configuration:

- git clone https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3.git

- cd Open-Vehicle-Monitoring-System-3/vehicle/OVMS.V3

- git submodule update --init --recursive

- cp support/sdkconfig.default.hw31 sdkconfig

- make menuconfig

If I run the make app command I get the following error:

make app

As it happens I've been trying the same on my mac (10.15).  I created a little install script and a seperate environment script.

dev.sh :

#!/bin/sh

# sudo easy_install pip
# pip install --user pyserial
# brew install ccache cmake ninja
# /System/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python -m pip install --user -r /Users/plord/src/ovms/esp/esp-idf/requirements.txt

set -e

XTENSA=xtensa-esp32-elf-osx-1.22.0-80-g6c4433a-5.2.0.tar.gz

if [ ! -d esp ]
then
if [ ! -f ${XTENSA} ]
then
wget  https://dl.espressif.com/dl/${XTENSA}
fi
mkdir esp
cd esp
tar -xzf ../${XTENSA}
git clone https://github.com/openvehicles/esp-idf.git
cd esp-idf
git submodule update --init --recursive
cd ../..
fi

. env.sh

if [ ! -d Open-Vehicle-Monitoring-System-3 ]
then
git clone https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3.git
cd Open-Vehicle-Monitoring-System-3
else
cd Open-Vehicle-Monitoring-System-3
git pull
fi
cd vehicle/OVMS.V3
git submodule update --init --recursive
cp support/sdkconfig.default.hw31 sdkconfig
make menuconfig
make app

env.sh :

PATH=$(pwd)/esp/xtensa-esp32-elf/bin:$PATH
export PATH

IDF_PATH=$(pwd)/esp//esp-idf
export IDF_PATH


Build completed

I didn't see any obvious difference to what you ran.
