Unknown attribute

[Jacek Laskowski 57]

How to set Delphi compiler to stop with error on classes where unknown attributes were used (no appropriate units in the uses section)?

 

Delphi 10.3

[Der schöne Günther 316]

I don't have my RAD Studio in English, so the translation might be off:

 

Project options -> Delphi Compiler -> Hints and Warnings -> Not supported language Features

 

You can set this from "True" to "Error" so the compilation will stop.

In previous versions of delphi I did so, in 10.3 it doesn't work, that's why I asked a question.

Err... according to that there is supposed to be new warning so current behavior is fine, but I cannot see it nor turn it on. (except with compiler directives)

Yes, my comment to Marcos post remained unheard. We should create a separate QP entry for that.

There is no access to such a warning! In turn, the compiler directive does not work globally, but locally (per unit), so it is useless.

[Uwe Raabe 2057]

In Project Options - Delphi-Compiler - Compiling add the following value to Additional options to pass to the compiler: -W^UNKNOWN_CUSTOM_ATTRIBUTE

Reported as 

Unknown attribute can only be turned to error via compiler directive

Arghhhh... who designs this stuff? Some warnings can be setup at one place, other in another... it is a mess...

That is only a workaround until the dialog allows setting it directly. The mentioned option is a last resort to tweak the command line parameters given to the compiler.

If the things were done right in the first place we would not need workarounds.

If things were always done right in the first place neither the term bug nor the term workaround would exist.
