Compiler Talk (Again)

1 min read

Talking to compiler is just like to human being, if you do not understand the dialect then you keep wondering what the other side is trying to say:

error C2663:  'QWidget::move': 1 overloads have no legal conversion for 
'this' pointer

That is from Microsoft VC++ compiler. If you are new, this message hardly tells you anything useful. So, open up MSDN help or fire Google.

But time is money:

error: passing `const Foo' as `this' argument of `void QWidget::move(int, int)' 
discards qualifiers

and the way how GCC spots the same mistakes easily sparks your brain cells and in matter of milliseconds, you know what you’ve done wrong.
