Hi! I’m trying to configure the project for esp32 board, and when i run ./waf configure --board esp32s3devkit, I get the following error using WSL:

config.log (4.5 KB)

I tried cygwin too, but there the compiler is not found for esp32 board but if I only run ./waf configure, the compiler is found…

And this is the log for this error above:
config.log (6.2 KB)

After a long research I found the solution.
It was my mistake because i didn’t install ESP-IDF.

So I followed carefully this page: ardupilot/libraries/AP_HAL_ESP32/README.md at master · ArduPilot/ardupilot · GitHub
Pay attention to step 3, it is very important!

In my case after compiling the software, when I made a change to the configuration file and wanted to recompile, the error was still there so if you want to compile again the software you’ll need to do this steps again:

cd modules/esp_idf
./install.sh
source ./export.sh

And then you can run ./waf configure --board=BOARD_TYPE and ./waf copter or plane to build.
