It is referenced and I still get undefined reference issue

class base_rec { 
    public: 
        base_rec():str(" "){}; 
        base_rec(string contentstr):str(contentstr){}; 
        void showme() const; 
    protected: 
        string str; 
    
};

class u_rec:public base_rec {
    public:
        u_rec():base_rec("undergraduate records"){};
        void showme() { cout << "showme() function of u_rec class\t"
            << str << endl;}
     
};
class g_rec:public base_rec {
    public:
        g_rec():base_rec("graduate records"){};
        void showme() { cout << "showme() function of g_rec class\t"
            << str << endl;}
};

int main() {
 base_rec *brp[2];
 brp[1] = new u_rec;
 brp[2] = new g_rec;
 for (int i=0; i<2; i++) {
 brp[i]->showme();
 }
}

Error Message:

main.cpp:(.text+0x58): undefined reference to `base_rec::showme() const' collect2: error: ld returned 1 exit status.

How can I fix it! the showme() is defined in base_rec
