How can I edit the CMakeLists.txt in my project with the Dht library added?

[kayasemih]

I am using Esp32 devkit V1 in my project. I couldn't find how to revise the CmakeLists.txt files in esp-idf. The error I get when I build idf.py is as follows:

/home/.../workspace/esp_projects/test_dht11/main/main.c:4:10: fatal error: dht.h: No such file or directory
 #include <dht.h>
          ^~~~~~~
compilation terminated.
make[2]: *** [esp-idf/main/CMakeFiles/__idf_main.dir/build.make:76: esp-idf/main/CMakeFiles/__idf_main.dir/main.c.obj] Error 1
make[1]: *** [CMakeFiles/Makefile2:4670: esp-idf/main/CMakeFiles/__idf_main.dir/all] Error 2
make: *** [Makefile:136: all] Error 2
make failed with exit code 2

I used dht.c and dht.h files in the same way in the dht folder. I just set the necessary places for me to use dht11.
My project folder is as below :

- main
      main.c 
      CMakeLists.txt
- core
      -inc
               dht.h 
               esp_idf_lib_helpers.h

      -src
               dht.c
      -CMakeLists.txt
-build
-CMakeLists.txt
       

My top level CMakeList.txt is as follows :

cmake_minimum_required(VERSION 3.5)

set(EXTRA_COMPONENT_DIRS $ENV{IDF_PATH}/home/../../../test_dht11/core)

include($ENV{IDF_PATH}/tools/cmake/project.cmake)
project(test_dht11)

Inside my core file CMakeList.txt is like this.I've intentionally commented some places here. Honestly, it shouldn't be like this. I left it that way as I couldn't figure out how to edit it. This part confused me the most.

#if(${IDF_TARGET} STREQUAL esp8266)
##    set(req esp8266 freertos log esp_idf_lib_helpers)
##else()
##    set(req driver freertos log esp_idf_lib_helpers)
##endif()
set(sources 
    src/dht.c

)

idf_component_register(
    SRCS ${sources}
    INCLUDE_DIRS "inc"
    REQUIRES driver
            freertos
)

Inside my main file CMakeList.txt is like this

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

Thanks in advance for your help.

i cannot solve your issue because:

• you omitted logs
• you did not follow the instruction in README.md in this repository
• some explanations do not make sense (you have three CMakefile.txt, which one are you referring to?)

it seems that you are not very familiar with cmake, or compiling C in general. if so, start from the example provided in esp-idf. the official documentation also recommends to copy an example, and modify it one by one. tree is a useful tool that you should have in your toolbox.

Hi!
You don't need to copy files from esp-idf-lib to your project. You can add whole esp-idf-lib as submodule.
See for example this project: https://github.com/UncleRus/EvLamp
