Hi @aaronse ,
i am trying to compile HelloWorld example, but i got error on LITTLEFS:

Here is my platformio.ini:

Are you able to help me to get this working? Many Thanks

Hi.
I downloaded your example 1:1 and try to compile it.
Get following error (installed the wifimanager lib manually, too).

warning: Calling missing SConscript without error is deprecated. Transition by adding must_exist=False to SConscript calls. Missing SConscript 'C:\lib\esp8266-iot-framework\scripts\preBuild.py' File "C:\Users\lars\.platformio\penv\lib\site-packages\platformio\builder\main.py", line 189, in <module> Compiling .pio\build\esp32dev\src\helloWorld.cpp.o Generating partitions .pio\build\esp32dev\partitions.bin Compiling .pio\build\esp32dev\lib126\AsyncTCP\AsyncTCP.cpp.o Compiling .pio\build\esp32dev\lib30b\FS\FS.cpp.o Compiling .pio\build\esp32dev\lib30b\FS\vfs_api.cpp.o In file included from src\helloWorld.cpp:10:0: .pio\libdeps\esp32dev\WiFiManager/WiFiManager.h:16:25: fatal error: ESP8266WiFi.h: No such file or directory

Edit: Hold on. I used the default iot-framework and not your´s. Will report.

New errors:

Hi Aaronse
Now I found some time to test your examples. Out of the box compiling of the helloWorld example throw an error:

In platformio.ini I added your repo for framework:

`; PlatformIO Project Configuration File
;
; Build options: build flags, source filter
; Upload options: custom upload port, speed and extra flags
; Library options: dependencies, extra library storages
; Advanced options: extra scripting
;
; Please visit documentation for the other options and examples
; https://docs.platformio.org/page/projectconf.html

[env:esp32dev]
board = esp32dev
platform = espressif32
lib_ldf_mode = deep
framework = arduino
monitor_speed = 115200
upload_speed = 921600
lib_deps =
ESP Async WebServer
ArduinoJson
LittleFS_esp32
Wire
https://github.com/aaronse/esp8266-iot-framework
build_flags = -DCONFIG_PATH=src/configuration.json -DREBUILD_CONFIG -DREBUILD_HTML -DLOG_LOCAL_LEVEL=ESP_LOG_DEBUG

preBuild.py script regenerates 1) HTML page (via webpack), 2) config objects, 3) Certificate store.

extra_scripts = lib/esp8266-iot-framework/scripts/preBuild.py
`

Any idea?
