I'm trying to add create a map with the string key and the abstract class value with this code
using Commands = = std::map<std::string, std::shared_ptr<spyCBlockRPC::IRPCCommand>>;
RPCCommandMediator {
public:
Commands commands = {
{"DECODE_SCRIPT_COMMAND", std::shared_ptr<IRPCCommand *>(new DecodeScriptCommand())},
};
}
How the abstract class is written by this code
class IRPCCommand
{
public:
virtual void doCommand(WrapperInformations &wrapper, BitcoinAPI &bitcoinApi) = 0;
};
The concrete class is written by this code
class DecodeScriptCommand : public IRPCCommand
{
public:
DecodeScriptCommand();
void doCommand(WrapperInformations &wrapper, BitcoinAPI &bitcoinApi) override;
};
and the file CPP is
DecodeScriptCommand::DecodeScriptCommand() : IRPCCommand(){}
void DecodeScriptCommand::doCommand(WrapperInformations &wrapper, BitcoinAPI &bitcoinApi)
{
//Operations
}
When compiling it, I have this error

Some information
I have read this and this but I don't fix my error (maybe I don't undestend it)
