我已经起床了 10 个小时试图弄清楚这一点。我尝试了一堆不同的库来尝试让 ogg 或 mp3 文件与 allegro 4 一起播放。我下载了 DUMB 库并将包含和 lib 文件复制到 mingw 各自的位置（我使用代码块）。将库安装到我的编译器的正确方法是什么？到目前为止，这是我的代码..

#include <allegro.h>
#include <iostream>
#include <stdlib.h>
#include <aldumb.h>


#include "CUSTOM_FUNCTIONS_HEADER.h"
#include "status_screen_functions_header.h"

#define WHITE makecol(255,255,255)

//General Game Settings
int volume = 128;
int pan = 128;
int pitch = 1000;

#
int main(int argc, char *argv[]){


    allegro_init();
    atexit(&dumb_exit);//initialize dumb
    dumb_register_stdfiles(); //tELL DUMB HOW TO OPEN FILES

    install_keyboard();
    if(install_sound(DIGI_AUTODETECT, MIDI_NONE, "") != 0){

        allegro_message("error initializing the sound system");

    }

DUMB 要求您链接两个库，即核心 libdumb 和 aldumb “胶水”。看起来你只与后者链接。订单也很重要。

请注意，DUMB 用于播放 MOD 文件（以及各种变体）。如果你想要 ogg 支持，如果你安装了官方的 ogg 库，它会内置在 Allegro 4.4 中。

此外，如果您刚刚开始，那么您应该真正使用 Allegro 5。版本 4 不再受真正支持，并且在现代操作系统上也无法正常工作。
