i i tried to update framework with : https://docs.espressif.com/projects/esp ... index.html and still show same error, all other library work well

i i tried : idf.py clean, idf.py fullclean too but both did not help.

Hi mohasrj,

Which ESP-IDF version are you using?

If you have C++ exceptions disabled in the project config (disabled is the default), then this looks the same as these two issues: https://github.com/espressif/esp-idf/issues/5363 & https://github.com/espressif/esp-idf/issues/5224

There is a pull request here to fix the issue in master, and a patch here to fix the issue in v4.0.

If you have C++ exceptions enabled in the config then this may be something else, will need some more detail (such as the ESP-IDF version) to debug.

thanks, i thinks it work i when i install esp idf version : v4.0.1 ( https://docs.espressif.com/projects/esp ... index.html) and i didnt past those component in esp idf : https://github.com/UncleRus/esp-idf-lib and i dont think they not use c++ library but without it i dont have error, or maybe i cant put theme with components esp idf
