Downloaded latest esp32 core and during compilation now getting an error saying to enable exception handling using -fexceptions. Is this a Visual Micro or compiler setting? Anybody know how to do this? sdconfig.h file has #define CONFIG_CXX_EXCEPTIONS 1 already enabled but I still get this error..

Thank for the quick reply. If I delete the espressif folder that will delete my entire esp32 core installation set of files and libraries? Is that what you really meant me to do?

Thanks! You pointed me in the right direction with the platform.txt file. I have been building on esp32 for over a year but the latest core I downloaded from GitHub for esp32 has in the platform.txt file -fno-exceptions and -fexceptions both flags set for the cpp compiler!. There is a comment in the GitHub about this. I just deleted the -fno-exceptions and restarted the ide and it works fine now. 

Cheers
