Alexander I.

Here is the code: #include <REST.Json.hpp> ... TJson* formatter=new TJson(); Compilation successful, but linker says following: [ilink32 Error] Error: Unresolved external 'Rest::Json::TJson::' referenced from C:\USERS\ISKOR\DESKTOP\TJSONTEST\WIN32\DEBUG\UNIT1.OBJ How can that be? I use C++ Builder 10.1 Community Edition.

Thank you for the explanation!

That worked! Thank you! But why it does not work by default, that is the question.
