esp32-s3 board compilation error #9
Description
I get a linker error on esp32-s3 board (arduino espressif 3.2.0, idf 5.4.0, cpp23)

// ArduinoLog.cpp
template<typename... Args> void Logging::writeLog(Args... args) {
for (int i = 0; i < _handlerCount; i++) {
if (_logOutputs[i]) {
_logOutputs[i]->print(args...);
}
}
}If I move the writeLog within the class in declaration file compilation works.
// ArduinoLog.h
// ...
private:
template<typename... Args>
void writeLog(Args... args) {
for (int i = 0; i < _handlerCount; i++) {
if (_logOutputs[i]) {
_logOutputs[i]->print(args...);
}
}
}
