Compiler doesn't throw warnings for a function not returning valid type #681
Description
For hours i was stuck when my mcu was going in an indefinite loop. Later i found that one of the function was being called continuous in loop, while i called that function only once.
Later i discovered that it was because the parent function which was calling this function had a syntax of return bool, but in code, i forgot to return anything.
void func1();
// Faulty Method
bool myfunction(){
func1();
// Forgot to return a boolean value.
}
void myMainFunction(){
int a = 0;
myfunction();
}
I was wondering if compiler can throw the error for such function.
I am not sure, i think maybe these compiler warnings could be out of scope from the arduino core. Or is there any option, to enable warning levels etc at the compilation time.
