How can I achieve deletion of StringWriter objects?

Hey everyone, I am using avr-g++ compiler on Windows for an AVR chip . I need to delete a StringWriter object created from a pointer to PacketWriter. As I define a destructor for StringWriter wether virtual or not, it leads to this error and similar ones. What could cause the 'undefined reference' error?

Undefined reference to 'operator delete(void*)'

Undefined reference to 'operator delete(void*)'

My PacketWriter.h:

class PacketWriter {
public:
    virtual ~PacketWriter() {}
    virtual uint8_t nextByte() = 0;
}

class PacketWriter {
public:
    virtual ~PacketWriter() {}
    virtual uint8_t nextByte() = 0;
}

StringWriter.h:

class StringWriter : public PacketWriter {
public:
    StringWriter(const char* message);
    virtual uint8_t nextByte();
}

class StringWriter : public PacketWriter {
public:
    StringWriter(const char* message);
    virtual uint8_t nextByte();
}

How can I achieve deletion of StringWriter objects in this context? @Middleware & OS
