自去年 12 月以来，我曾问过这个问题，但到处都被忽略了，所以我想最后一次问这个问题。

我正在尝试加载音频文件（作为 Mix_Chunk），但收到以下错误消息：

“找不到 RIFF 或 WAVE 标识符（不是波形文件）”

我尝试了我所知道的 Audacity 中的所有导出设置，我在这里做错了什么？

我做的一切都是正确的，我什至使用十六进制编辑器进行了检查，并且标识符在那里。 十六进制编辑器中的文件

我尝试的任何文件格式都会出现此问题。FOpen 也能够完美地读取标识符字节，问题可能是什么？

我正在使用 gcc 在 Ubuntu 机器上编译。我使用包管理器来安装所有东西。

编码：

#include <SDL2/SDL.h>
#include <SDL2/SDL_mixer.h>
#include <string>
#include <iostream>
int main() {
    int Mixer = Mix_OpenAudio( 44100, MIX_DEFAULT_FORMAT, 2, 2048 );
    if(Mixer < 0)
    {
        std::cout << "Mixer wasn't initialized.";
        return 0;
    }
    if( SDL_Init( SDL_INIT_AUDIO ))
    {
        std::cout << "Sdl audio wasn't initialized.";
        return 0;
    }

    Mix_Chunk *mc = Mix_LoadWAV("YouGotMail.wav");
    
    if (!mc)
    {
        std::cout << std::string(std::string("Failed to load audio YouGotMail.wav.\n") + Mix_GetError()).c_str() << std::endl;
        return 0;
    }
    return 0;
}

在可执行文件上使用 ldd 会给我这个输出：

我遇到的问题是我正在链接旧的 sdl 混合器，它不适用于 SDL2，将 lSDL2_mixer 库添加到我的 make 文件中修复了错误，非常感谢 keltar 和 danadam 指出这一点。
