How to include subcomponents inside ESP-IDF

[veso266]

Hello there, its my first time developing with ESP32 and using its ESP-IDF Build System

I created a project with

idf.py create-project BlueFW
idf.py set-target esp32
idf.py menuconfig
to enable Bluetooth and C++ exeptions

then I started adding files inside


my CMakeLists.txt inside main looks like

Code: Select all

idf_component_register(SRCS "main.cpp" "BLENotifyApp.cpp"
                    INCLUDE_DIRS ".")

But linker does not want to link it complains

Code: Select all

Executing action: all (aliases: build)
Running ninja in directory L:\projects\me-projekto\projektoHW\build
Executing "ninja all"...

I know the classes and files are there so how do I tell this to linker, how do I include all my files, so linker will know what to do?

Thanks for Anwsering and Best Regards

You don't need to reference the component files in your main CMakeLists.txt, the component itself needs a CMakeLists.txt that makes esp-idf compile them. Also, your 'component' directory should be in the root of your project, not in the 'main' folder.
