GLFW 库无法使用 bgfx 初始化

Question

我只是想用glfw学习bgfx，我的代码确实可以编译，但是当我尝试运行该程序时，我遇到了一些错误

#define WDW_WIDTH 1280
#define WDW_HEIGHT 720

#define GLFW_INCLUDE_NONE

#if defined (_WIN32)
#define GLFW_EXPOSE_NATIVE_WIN32
#elif defined (__linux__)
#define GLFW_EXPOSE_NATIVE_X11
#elif defined (__APPLE__)
#define GLFW_EXPOSE_NATIVE_COCOA
#endif

#include <iostream>

#include <GLFW/glfw3.h>
#include <GLFW/glfw3native.h>
#include <bgfx/bgfx.h>
#include <bgfx/platform.h>

auto GetNativeWindow(GLFWwindow* window) {
    #if defined (GLFW_EXPOSE_NATIVE_WIN32)
        return glfwGetWin32Window(window);
    #elif defined (GLFW_EXPOSE_NATIVE_X11)
        return (void*)(uintptr_t)glfwGetX11Window(window);
    #elif defined (GLFW_EXPOSE_NATIVE_COCOA)
        return glfwGetCocoaWindow(window);
    #else
        std::cout << "undefined platform\n";
    #endif
}

Display* GetNativeDisplay() {
    #if defined (GLFW_EXPOSE_NATIVE_WIN32)
        return NULL;
    #elif defined (GLFW_EXPOSE_NATIVE_X11)
        return glfwGetX11Display();
    #elif defined (GLFW_EXPOSE_NATIVE_COCOA)
        return NULL;
    #else
        std::cout << "undefined platform\n";
        return NULL;
    #endif
}

static void error_callback(int error, const char* description) {
    std::cout << "Error [" << error << "] : " << description << "\n";
}

int main() {

    glfwSetErrorCallback(error_callback);

    if (!glfwInit()) {
        error_callback(1, "failed to init glfw");
        glfwTerminate();
    }
    
    GLFWwindow* window = glfwCreateWindow(WDW_WIDTH, WDW_HEIGHT, "GAME", nullptr, nullptr);
    if (window == nullptr) {
        error_callback(2, "failed to create window");
        glfwTerminate();
    }

    glfwMakeContextCurrent(window);

    bgfx::Init bgfx_init;
    bgfx_init.type = bgfx::RendererType::Count; // Automatically choose a renderer.
    bgfx_init.vendorId = BGFX_PCI_ID_NONE;
    bgfx_init.resolution.width = WDW_WIDTH;
    bgfx_init.resolution.height = WDW_HEIGHT;
    bgfx_init.resolution.reset = BGFX_RESET_VSYNC;
    if (!bgfx::init(bgfx_init)) {
        error_callback(1, "failed to init bgfx");
        glfwTerminate();
    }
    
    bgfx::PlatformData pd;
    pd.ndt = GetNativeDisplay();
    pd.nwh = GetNativeWindow(window);
    bgfx::setPlatformData(pd);

    bgfx::setViewClear(0, BGFX_CLEAR_COLOR | BGFX_CLEAR_DEPTH, 0x443355FF, 1.0f, 0);
    bgfx::setViewRect(0, 0, 0, WDW_WIDTH, WDW_HEIGHT);
    

    while (!glfwWindowShouldClose(window)) {
        bgfx::frame();
        glfwPollEvents();
    }

    bgfx::shutdown();
    glfwDestroyWindow(window);
    glfwTerminate();    

    return 0;
}

错误：

Error [1] : failed to init bgfx
Error [65537] : The GLFW library is not initialized
Error [65537] : The GLFW library is not initialized
Segmentation fault (core dumped)

当我删除 bgfx 代码只留下 glfw 时，一切都正常工作，并且 glfw 初始化没有错误（也许）。

我也尝试过使用SDL2，但它也有相同的错误（分段错误（核心转储））。

glfw 和 bgfx 库与 vcpkg 一起安装 并使用 makefile 进行构建，我的操作系统是 Linux Ubuntu 22.04.3 LTS

我只是想学习bgfx。

修复方法是不使用

bgfx::setPlatformData(pd);

设置平台数据。 相反，我将平台数据设置到 bgfx_init 变量中

    bgfx::Init bgfx_init;
    bgfx_init.type = bgfx::RendererType::Count; // Automatically choose a renderer.
    bgfx_init.vendorId = BGFX_PCI_ID_NONE;
    bgfx_init.resolution.width = WDW_WIDTH;
    bgfx_init.resolution.height = WDW_HEIGHT;
    bgfx_init.resolution.reset = BGFX_RESET_VSYNC;
    bgfx_init.platformData = pd;
    if (!bgfx::init(bgfx_init)) {
        error_callback(1, "failed to init bgfx");
        glfwTerminate();
    }
