External library with kconfig not shown when running menuconfig from PIO tasks menu

#1

Greetings all,

I’m creating an external library for which there is some configuration elements put in a kconfig file. From another project, I identify this library as a dependency in the platformio.ini file as follow:

[env:esp32doit-devkit-v1]
platform=https://github.com/platformio/platform-espressif32.git
board           = esp32doit-devkit-v1
framework       = espidf
monitor_filters = colorize
monitor_raw     = yes
build_flags     = -std=gnu++17
upload_speed    = 256000
upload_port     = /dev/ttyUSB0
monitor_speed   = 115200
monitor_port    = /dev/ttyUSB0
lib_ldf_mode    = chain+
lib_compat_mode = strict
lib_deps = https://github.com/turgu1/esp32-simple-iot-framework.git

I’ve tried naming the kconfig file as Kconfig, Kconfig.projbuild, putting the file in both the root folder of the library and inside the src/ folder, I can’t get the configuration elements shown in the menuconfig display.

The library is Here

So my question is: What is the proper way of defining kconfig in an external library such that it will appears in menuconfig?

Thanks!!!

Thanks max,

From the link you provided, it seems that this issue has not been resolved yet. Am I correct?

I tried to add the following to the main CMakeList.txt file of the project, as proposed here, but it doesn’t work either:

list(APPEND EXTRA_COMPONENT_DIRS ${CMAKE_SOURCE_DIR}/.pio/libdeps/ESP32SimpleIOT)

I’m clueless. I will then copy the content of the Kconfig to the project’s Kconfig.projbuild then, unless there is a better solution!

Exactly.

Well usually you don’t add ESP-IDF libraries via lib_deps but as a component, so have you tried creating a components folder in the project and clone your library in there? Like the example does.

At first, it was a library created following the PIO documentation as described here. Seeing that I was not able to have Kconfig to appear in menuconfig, I’ve added the other ESP-IDF required files to try to find a solution.

I’ve tried to move the library in a folder under components (and removed the lib_deps line in platformio config file). Now, I can’t get the PIO Run menuconfig command in the menu. :roll_eyes:

I’ve returned back to a clean external library (in the PIO senses) as I removed the CMakeLists files and the library.property file, and returned back with the lib_deps line in the platformio config file. Still not working.

I prefer keeping the library out of the targeted project, as there is a lot of modifications to do and many projects will need access to the library. Hope that a solution will come through a future update to PIO.

Thanks for you help!!

P.S.: I understand that PlatfomIO is an Ukrainian project. I hope that this war will end soon as those people are suffering a lot. This is nonsense.

Hello everybody. Just noticed exactly the same behavior. It would be really nice to have library’s Kconfig file discoverable by menu config. I was wondering if there is a potential workaround? Thanks!
