No pointer to error but not build

1

Hello,

I am new into the Arduino and Platformio so sorry if I do something in the wrong way… when I try to build the project - no error but build is FAILED, could the log below help resolve my problem? thanks in advance.

These errors from the linker indicate that at the call to those functions at line 862 of your main.cpp (in a function called handleNewMessages()?), the function declaration for those functions was found (the .h / myFunc(); lines) had been found, but not the function definition (the matching .cpp / actual body the the function). Same goes for StartTime()
