Component example

[wmarchewka]

Im using Esp-idf v5.4.0. I used the new Project Wizard and choose a template-app. I downloaded the esp_matter component using the esp-idf:show component registry. I added #include "esp_matter.h" to the main.c and changed to main.cpp.
when i build i get 246 issues. I attached a build_log. Any ideas?

As a side note, i did get esp-matter installed using the guide here and was able to successfully build and talk to the light app using rainmaker.

https://docs.espressif.com/projects/esp-matter/en/latest/esp32/developing.html#esp-matter-setup

`#include <stdio.h>
#include "esp_matter.h"
#include "esp_log.h"
const char *TAG = "main";

void app_main()
{
ESP_LOGI(TAG, "Hello, world!\n");
}
`
build_log.txt

Could you try add the property idf_build_set_property(CXX_COMPILE_OPTIONS "-std=gnu++17;-DCHIP_HAVE_CONFIG_H" APPEND) in the project's CmakeLists? And use extern "C" void app_main() in main.cpp.

That fixed it, thank you very much for the quick response.
