mdf_info_load() fails in C++

Postby LahiruLKR » Mon Nov 11, 2019 1:39 pm

Currently, I am using ESP MDF to build a firmware for esp32 in C++. When using the function mdf_info_load() with "mdf_info_store.h" included, I get the following error.

Code: Select all

The issue is with "__builtin_types_compatible_p" which only supports C. I found the following discussion regarding the same issue that has occured in "mwifi.h".

https://github.com/espressif/esp-mdf/issues/17

Seems like "mdf_info_store.h" in the MDF library should be modified in the way you (ESP developers) modified "mwifi.h".
Appreciate if you could resolve this issue asap.
