Problem porting from ESP8266 to ESP32

I have a program written for ESP8266. I would like to port it to ESP32.

All errors I understand have been solved. Now I end up with a list of errors referring to: filename_proto.h

What should I do?


It would still be good to get

It would still be good to get an idea of what the errors were though - in case there is a bug in UECIDE. There is one that I do know of and is cured in later versions whereby it doesn't like functions that return a pointer if the * is coupled to the function name (char *foo() {...} instead of char * foo() {...}).
