I'm running into a problem when using the SDL2 Mixer library in my C++ project. As soon as I'm calling a function on a class that #includes SDL_mixer.h, the project will not run. When trying to Run it, I get the following message:
When debugging the project, the process finishes with exit code 0, but with an additional message:
and
As you might be able to deduce, adding breakpoints to the code does not provide any additional information as the project doesn't start at all.
Commenting out the lines that use the class that include mixer makes the project runnable again seemingly without issues. I've tried to google the error code, but I can't find any documentation on what it means.
Other, possibly relevant information: I'm using conan to install my libraries and have it set to auto-install any dependencies.
I'll post the header code of the class in question here, though I don't believe the problem lies here as the project won't run to even reach the code anyway.
#include <SDL.h>
#include <SDL_mixer.h>
#include <memory>
#include <string>
#include <map>
class SoundService {
public:
/*******************************************************************************

static std::unique_ptr<SoundService> &getInstance() {
if (instance == nullptr) {
if(Mix_OpenAudio(44100, MIX_DEFAULT_FORMAT, 2, 4096) < 0){
SDL_Log("Mixer Initialization Error: %s", Mix_GetError());
}
instance = std::unique_ptr<SoundService>(new SoundService());
}
return instance;
}

private:
SoundService() = default;
static std::unique_ptr<SoundService> instance;
std::map<std::string, Mix_Music *> musicMap;
std::map<std::string, Mix_Chunk *> sfxMap;
};
The function that I'm calling that breaks the project is just a simple line of testcode:
auto& soundService = SoundService::getInstance();
Here is the conanfile used to declare the required libraries:
from conans import ConanFile, CMake
from conans.tools import os_info
class ModularMagicConan(ConanFile):
name = "ModularMagic"
version = "0.1"
url = "edited out"
description = "A 2D game"
settings = "os", "compiler", "build_type", "arch"
generators = "cmake"

self.requires("sdl2_mixer/2.0.4@bincrafters/stable") # SDL2 mixer, sound library

self.requires("box2d/2.4.0") # Box2D, physics library
def build(self):
cmake = CMake(self)
cmake.configure()

Anyone familiar with this issue or has any idea what's causing it and how to resolve it?
