Hi Guys,

With reference to FPC 2.2.4 Linux, can somebody please explain how to get the compiler to compile code that uses the Experimental and Unimplemented hint directives?

An expanation is given on their use on page 11 of the Reference Guide for Free Pascal, version 2.2.4, but I have no luck making use of them.

The compiler recognizes the Experimental directives as an identifier and the compilation fails with a syntax error. The Unimplemented directive does not seem to be recognized by the compiler.

I understand that these directive are for the output of hints only during the compile process, but it would be a good thing to have them work, (assuming that the programmer has hints on and reads/notices the hints).

Regards,
Nino

The Unimplemented directive is ignored if used in the interface section (as a global exported function/procedure). The directive only emits a hint if its used with a function/procedure within the implementation section and is not globally exported (i.e. function definition does not appear in the interface section).

Perhaps this is the intention of the directive designer? Would it be useful to have a globally exported Unimplemented function? Who am I to say no?
