Lokale Kopie von System.Variants.pas einbinden und nutzen, geht das?

Zitat von Rollo62:

Immer mit dem Fehler
"[dcc32 Fatal Error] System.Variants.pas(1271): E2158 System.Variants unit out of date or corrupted: missing '@VarCast'"

VarCast is declared as _VarCast, so in theory to make it work you need to strip all the functions in System.Variants.pas from these and adjust the whole unit to call them stripped code, though there might be something hidden to surprise you, which need to adjust system.pas itself, that most likely impossible with Delphi compiler.

If rebuilding the whole RTL (after making changes) is possible then that is the right way, in my opinion.
In case you succeeded in rebuilding the RTL, then i suggest to add global hooks with minimum interaction with the current code and declarations, these hooks and callback can be used for logging, and the RTL might still be compatible with default RTL, just food for thought.
