CodeBlocks+ PIO + ESPDIF won't compile. ->Could not find “sdkconfig.json” file

Hello,
im trying to compile the project in codeblocks, but getting the following error:

The platformio.ini :

[env:esp32doit-devkit-v1]
platform = espressif32
board = esp32doit-devkit-v1
framework = espidf
monitor_speed = 115200
lib_deps = 
	id=246@^2.6.2
	ESPUI
	ESPAsyncWebserver
	64
	ESPAsyncTCP
board_build.f_cpu = 160000000L

should i change the “framework” to “Arduino” - i get the project to compile.

the main.cpp:
 #include <time.h>
#include "sdkconfig.h"
#include "driver/gpio.h"
#include "esp_log.h"

#include <Sensor_DHT.h>
#include <sensor.h>
#include <gui.h>
#include <net.h>

Please advise.

You have specified that you want to compile for the espidf framewokr but you are including Arduino libraries which are not compatible by default.

ESP-IDF project need to have specific files (CMakeList.txt etc), see https://github.com/platformio/platform-espressif32/tree/develop/examples/espidf-blink. Without these, errors occur.

Spot on! Thank you., Maximillian
