ESP-IDF CMake Error on ESP32C6 Board - Missing CJSON.c File
Hi everyone! I'm experiencing a build error with ESP-IDF on my ESP32C6 board and I'd appreciate some help. I'm trying to build the "blink" example in the get-started directory.
Error Message:
...
CMake Error at /home/vboxuser/esp/esp-1df/tools/cmake/component.cmake: 479 (add_library): Cannot find source file: /home/vboxuser/esp/esp-1df/components/json/cJSON/CJSON.c
...
CMake Generate step falled. Build files cannot be regenerated correctly.
...
Troubleshooting Steps:
Verified that ESP-IDF is installed correctly and the json component is included.
Double-checked that the file path /home/vboxuser/esp/esp-1df/components/json/cJSON/CJSON.c exists (although this likely won't be your actual path on an ESP32C6 project).
Ran idf.py clean and idf.py build, but the error remains.
Additional Information:
ESP-IDF version: (specify your version)
Operating system: (specify your OS)
ESP32C6 development board model: (specify your board model)
Any specific configurations or custom components in your project.
Steps you've taken to set up the ESP32C6 board and ESP-IDF environment.
Question:
Is there a specific configuration for building ESP-IDF projects on ESP32C6 boards that I might be missing?
Could the file path issue be related to differences in component structure for ESP32C6 compared to other ESP32 boards?
Thanks in advance for your assistance!

Have a look at this. You might want to include this manually in if not existing already.
Hi @Prachi Patil just make sure while installing Espressif IDE we've to manually checked the box
ESP32-C6 (ESP-IDF v5.1+) Please refer to the picture attached. I hope this may resolve linking and path related issues.
