Code developed in ESP-IDF Version 4.0, does not compile in version 4.3.1

[prvermas]

Hi,

The code is compiled in esp-idf 4.0 but is not compiling in version 4.3.1, using fresh setup on a new m/c as per the directions for the windows installer. I would appreciate if someone can look into this. The errors reported are for blufi api(s) linking (PS if I try to create a new blufi example it compiles properly)

Best Regards,
Pradeep

[ESP_Sprite]

Could you try removing the build directory (or running idf.py fullclean) and retrying?

[prvermas]

Yes I did this exercise of deleting the build folder altogether & cleaning the project.

Also tried executing build directly from the command prompt

In menuconfig, did you enable CONFIG_BT_BLE_BLUFI_ENABLE ?
