1 year ago Well, there certainly are a number of errors in the output.
error: 'ARDUINO_EVENT_WIFI_STA_DISCONNECTED' indicates that you're using the wrong version of arduino-esp32. You should be able to use the newest released version.
Then there are errors such as "error: enumeration value 'Off' not handled in switch" which is annoying. The value Off is not handled precisely because the desired effect is for nothing to happen in that case. The code probably should have an empty case block just for completeness but triggering an error on that is not something that should happen in C++ (now, Rust on the other hand will always do so). This is an easy fix in code but should have been, at most, a warning.
The error in Logger about too many arguments is strange. That code has compiled for years.
My guess is that VisualMicro is setting some extremely strict compile flags and the code is too sloppy to pass them. I always just used the Arduino IDE which also somewhat hid the avalanche of warnings. Well, I knew about some of them but none of them actually affect program performance and so fixing them has been a low priority.
