Hi,
I recently updated PlatformIO and Cmake (3.16 minimum was required). Since then linker doesn’t seem to see my lib.

I’ve linked a simple code just to isolate the issue.

Thanks :slight_smile:

Hi @Gabriel47! Looks like a bug, could you please try to organize your library as a full-fledged ESP-IDF component?
Just create a new CMakeLists.txt in library folder with the following contents:

idf_component_register(SRCS "lighting.c" INCLUDE_DIRS ".")

Then specify it in the main CMakeLists.txt near platformio.ini:

cmake_minimum_required(VERSION 3.16.0)
include($ENV{IDF_PATH}/tools/cmake/project.cmake)
list(APPEND EXTRA_COMPONENT_DIRS lib/lighting)
project(EHome)

@valeros looking at your example you show in your comment, are you saying i need this in the library folder or in the main src folder?
idf_component_registers(SRCS "lighting.c" INCLUDE_DIRS ".")

Hi @wegunterjr! This problem should be fixed is the latest version of the platform, so there is no need to specify it as a component if it’s a basic library, just put it in the lib folder.

I just found this thread and I am seeing the exact same problem as the original poster, on espressif32 with the espidf framework. I tried this on a new project with a dummy library and the header is not found.

platformio update shows everything up-to-date. This only happens with the espidf framework. With arduino as framework, this is fine.
