При запуске кода командой:

g++.exe App/main.cpp App/AppWindow.cpp GameEngine/WindowingSystem/Window.cpp GameEngine/GraphicsEngine/GraphicsEngine.cpp -o main.exe

Вылетает ошибка:

C:\Users\486B~1\AppData\Local\Temp\ccFUVirG.o:GraphicsEngine.cpp:(.text+0xae): undefined reference to `D3D11CreateDevice'
collect2.exe: error: ld returned 1 exit status

Почему возникает ошибка?

main, AppWindow, Window Я не привожу т. к. они не влияют на работу (я закомментировал кусочки где используется код GraphicsEngine)

Код GraphicsEngine.cpp:

#include "GraphicsEngine.h"

GraphicsEngine::GraphicsEngine()
{
}


bool GraphicsEngine::init()
{
    D3D_DRIVER_TYPE driver_types[]=
    {
        D3D_DRIVER_TYPE_HARDWARE,
        D3D_DRIVER_TYPE_WARP,
        D3D_DRIVER_TYPE_REFERENCE
    };
    UINT num_driver_types = ARRAYSIZE(driver_types);


D3D_FEATURE_LEVEL feature_levels[]=
{
    D3D_FEATURE_LEVEL_11_0
};
UINT num_feature_levels = ARRAYSIZE(feature_levels);

HRESULT res = 0;
for (UINT driver_type_index = 0; driver_type_index < num_driver_types;)
{
    res =D3D11CreateDevice(NULL, driver_types[driver_type_index], NULL, NULL, feature_levels,
        num_feature_levels, D3D11_SDK_VERSION, &m_d3d_device, &m_feature_level, &m_imm_context);
    if (SUCCEEDED(res))
        break;
        ++driver_type_index;
}
if (FAILED(res))
{
    return false;
}



return true;



}


bool GraphicsEngine::release()
{
    m_imm_context->Release();
    m_d3d_device->Release();
    return true;
}


GraphicsEngine::~GraphicsEngine()
{
}


GraphicsEngine * GraphicsEngine::get()
{
    static GraphicsEngine engine;
    return &engine;
}

Код GraphicsEngine.h:

#pragma once
#include <d3d11.h>

class SwapChain;
class DeviceContext;


class GraphicsEngine
{
public:
    GraphicsEngine();
    bool init();
    bool release();
    ~GraphicsEngine();
public:
    static GraphicsEngine* get();


private:
    ID3D11Device * m_d3d_device;
    D3D_FEATURE_LEVEL m_feature_level;
    ID3D11DeviceContext * m_imm_context;
};

Возможно, Вы не подключили библиотеку с этой функцией через -l? Тут пример подключения И конкретно по этой либе
