How do I set a SDK as external library?

[aero04]

Hi all!
I am new to this forum and to ESP32 but programmed microcontrollers in the past.
I want to use an ESP32C6 board to use it as a custom Zigbee device.
To introduce myself to that I successfully downloaded, compiled and programmed my board (using Visual Studio Code and the ESP-IDF extension) with the "HA_on_off_switch" example from the Zigbee SDK (https://github.com/espressif/esp-zigbee-sdk).

Now I want to seperate the Zigbee SDK from the "HA_on_off_switch" example. I want to do this because in the future I will have multiple projects being based on the Zigbee SDK and I don't want to download about 130MB ("managed_components" folder) into every project.

What I did so far:

• I uncommented the library dependencies in the file "idf_component.yml" of the "main" folder as following to avoid downloading it to the "managed_components" folder everytime:

  Code: Select all

  ## IDF Component Manager Manifest File
  dependencies:
   ## espressif/esp-zboss-lib: "~1.6.0"
   ## espressif/esp-zigbee-lib: "~1.6.0"
   ## espressif/led_strip: "~2.0.0"
    ## Required IDF version
    idf:
      version: ">=5.0.0"

• I registered these libraries (which are in a folder called "lib") in the "CMakeLists.txt" file of the "main" folder:

  Code: Select all

  string(REPLACE "\\" "/" IDF_PATH  ${IDF_PATH})
  idf_component_register(
      INCLUDE_DIRS "." "C:/Users/USER/Desktop/lib/esp-zigbee-lib/" "C:/Users/USER/Desktop/lib/esp-example-common/" "C:/Users/USER/Desktop/lib/esp-example-common/" "C:/Users/USER/Desktop/lib/esp-zboss-lib/" "C:/Users/USER/Desktop/lib/led_strip/"
  )

• In the ".vscode" folder of the project I modified the "c_cpp_properties.json" file and added the library folders:

  Code: Select all

  {
      "configurations": [
          {
              "name": "ESP-IDF",
              "compilerPath": "${config:idf.toolsPathWin}\\tools\\xtensa-esp-elf\\esp-14.2.0_20241119\\xtensa-esp-elf\\bin\\xtensa-esp32-elf-gcc.exe",
              "compileCommands": "${config:idf.buildPath}/compile_commands.json",
              "includePath": [
                  "${config:idf.espIdfPath}/components/**",
                  "${config:idf.espIdfPathWin}/components/**",
                  "${workspaceFolder}/**",
                  "C:/Users/USER/Desktop/lib/esp-zboss-lib/",
                  "C:/Users/USER/Desktop/lib/esp-zigbee-lib/",
                  "C:/Users/USER/Desktop/lib/esp-example-common/",
                  "C:/Users/USER/Desktop/lib/led_strip/"
              ],
              "browse": {
                  "path": [
                      "${config:idf.espIdfPath}/components",
                      "${config:idf.espIdfPathWin}/components",
                      "${workspaceFolder}",
                      "C:/Users/USER/Desktop/lib/esp-zboss-lib/",
                      "C:/Users/USER/Desktop/lib/esp-zigbee-lib/",
                      "C:/Users/USER/Desktop/lib/esp-example-common/",
                      "C:/Users/USER/Desktop/lib/led_strip/"
                  ],
                  "limitSymbolsToIncludedHeaders": true
              }
          }
      ],
      "version": 4
  }

My problem now is, that I get these two errors in VSCode:

Code: Select all

#include errors detected. Consider updating your compile_commands.json or includePath. Squiggles are disabled for this translation unit (C:\\Users\\USER\\Desktop\\Zigbee_on_off_light_test\\main\\esp_zb_light.c).
cannot open source file \"portmacro.h\" (dependency of \"C:\\Users\\USER\\.vscode\\extensions\\ms-vscode.cpptools-1.25.3-win32-x64\\bin\\freertos\\FreeRTOS.h\")"

And that the compiling does not finish with the following error:

Code: Select all

How do I fix this error?
Did I do something wrong ar am I missing something concerning the including of the library paths?

Thanks for any help in advance!

I don't want to download about 130MB ("managed_components" folder) into every project.

In a bash environment, the following will work:

Code: Select all

$ mv managed_components /home/esp32/lib

$ rm main/idf_component.yml

$ rm main/dependencies.lock

$ edit CMakeLists.txt and add this

set(EXTRA_COMPONENT_DIRS /home/esp32/lib)

$ idf.py build

idf.py uses components from /home/esp32/lib.
