Hello,

I have started to explore ESP2886 and ran into a snag trying to learn setting up a project. I am using the RTOS SDK and so far I have successfully build and flash the hello world and an example ds18X20 from this repository
https://github.com/UncleRus/esp-idf-lib

I am using the idf.py wrapper to build

If all files below are placed in main, I can compile fine. Once I try to make a project as on the build system on the ESP wiki, I run into the below linker error. I am not familiar with cmake, I only have experience with PIC XC8 compiler so I think I am just missing something. Any help and feedback on how to structure projects to build is appreciated!

I am using the ds18X20 multi files and created a project like so:
(spaces didn't work for formatting)
Temperature_Sensor (project folder)
---- CMakeLists.txt

---- sdconfig
---- main
-------- CMakeLists.txt

-------- main.c
-------- Kconfig.projbuild
---- components
-------- ds18b20
------------ CMakeLists.txt

------------ ds18x20.c
------------ include
---------------- ds18x20.h
------------ helper
---------------- CMakeLists.txt

---------------- esp_idf_lib_helpers.h
---------------- etc_sys.h
------------ onewire
---------------- CMakeLists.tx

---------------- onewire.c
------------ include
---------------- onewire.h
