FPC 3.0.2 (Linux x86_64)
Is Delphi SDK used? What version of Delphi? Did you setup .dcu a decompiler or just added SysUtils.pas to project paths?
No, this is not Delphi SDK, this is FPC 3.0.2 SDK. Example was from FreePascal wiki.
Is it still the case?
@argb32 yes. If open decompiled sysutils.dcu definition, here is the code:
procedure FreeAndNil( var obj: system.);
This shouldn't prevent finding FreeAndNil's declaration.
Does it highlight the procedure as undeclared identifier in your code?
Should be fixed now
