woran erkenn ich fehler beim komplimieren wenn keine fehlermeldung kommt?
oder wenn ich was falsch gemacht habe beim mappen.

Alt+P in Hammer und überprüfen, oder den Compile-Log mit dem Analyser prüfen.

There is nothing wrong with high standards. It's your problem that you don't meet them.
If you think it's simple, then you have misunderstood the problem.
When a customer says "nothing has changed", assume they're lying.
