Creating a map of Mix_Music?

I need to create a map of Mix Music with integers to play certain clips when needed. Here's what I have

AudioHandler.cpp
Code:
#ifndef __RunnyMan__AudioHandler__
#define __RunnyMan__AudioHandler__

#include <iostream>
#include <SDL2/SDL.h>
#include <SDL2_mixer/SDL_mixer.h>
#include <map>

class AudioHandler {
private:
    std::map<int, Mix_Music* > clips;
public:
    bool init();
    bool addClip(const char *, int);
};

#endif /* defined(__RunnyMan__AudioHandler__) */


AudioHandler.h
Code:
#include "AudioHandler.h"

bool AudioHandler::init(){
    if (Mix_OpenAudio(22050, AUDIO_S16, 2, 4096) != 0){
        return 1;
    };
   
    return 0;
};

bool AudioHandler::addClip(const char * filename, int index){
    Mix_Music * music = nullptr;
    music = Mix_LoadMUS(filename);
    clips[index] = music;
   
    return true;
};


However, I keep getting

Code:
No viable overloaded '='

Shouldn't that be std::map<int, Mix_Music*>; ? I can't see the template args in your code.

Code looks good to me. What's your compiler ?

That's not how you use a templated type.

Quote:

std::map <key_type, data_type, [comparison_function]>

Quote:

std::map <string, char> grade_list;

Quote:

grade_list["John"] = 'B';
